VoIP network administration With IBM | real Questions and Pass4sure dumps

IBM enterprise, headquartered in Armonk, ny, ranks among the many few businesses that has created computing and communications innovations for over a century.

incorporated in 1911 as the Computing-Tabulating-Recording enterprise (C-T-R), the firm's predecessors will also be traced to the Eighties with innovations equivalent to time clock to checklist a employee's arrival and departure time on paper tape, and the punched card system that become used to tabulate census information.

Thomas J. Watson, Sr., a former executive at national cash Register enterprise, joined C-T-R in 1914 and famously insisted on "well-groomed, darkish-perfect salesmen," and a company hub of attention on "big-scale, customized-constructed tabulating solutions for giant corporations".

His son, Thomas J. Watson, Jr., converted the business from maker of tabulating gadget and typewriters privilege into a pioneer of the computing business, introducing the system/360 mainframe in 1964.

these days, that focus has broadened extensively, with products that latitude from laptops to these tremendous mainframe systems, and an organization that serves both consumers and petite to tremendous corporations. IBM employs over 386,000 people worldwide, and, outright through 2007, recorded $ninety eight.6 Billion in income.

To boost their aid of the Token-Ring networking expertise, IBM delivered NetView/workstation in 1986, which accelerated the community management capabilities of IBM's methods network architecture.

IBM's network management assist travail become further improved in 1996 with the merger of IBM and Tivoli methods, Inc., a leading issuer of systems administration software for allotted client/server networks. IBM's acquisition of Tivoli prolonged its network administration capabilities beyond the mainframe to multi-platform, allotted systems. These initiatives bask in been extra reinforced with IBM's 2006 acquisition of Micromuse, Inc., and its Netcool line of business network management solutions.

The Tivoli software options provided integrated visibility, control, and automation throughout discrete enterprise and expertise property, accordingly maximizing those property in aid of community operations. These products tackle a wide selection of network management challenges, together with:

  • Asset management: presenting a comprehensive view of outright asset types throughout the commercial enterprise, including creation, amenities, transportation, and IT.
  • carrier management: permitting organizations to greater effortlessly and efficiently carry IT features including process and operational management items and premier practices consulting functions.
  • Server, community and machine management: enabling an conclusion-to-conclusion view of the IT infrastructure for resource allocation, monitoring, and provisioning.
  • Storage management: addressing the needs for obtainable and official guidance.
  • safety management: aiding the essential e-business challenges of automated identity administration and security event administration.
  • Mainframe management: monitoring the health and applications for IBM z/OS and OS/390 programs.
  • another distinguished enviornment it truly is supported by artery of the Tivoli suite of utility is the Netcool application for carrier providers, which gives actual-time efficiency and service management for service suppliers. IBM claims that over 1,000 carrier suppliers, together with the entire proper 20, import on this community management solution. This rig helps telecommunications, instant, cable, and web service suppliers in meeting both their latest and future service start challenges.

    Of particular interest is the provider VoIP service management solution, which is designed to assist outright layers within the network and outright links across it-from the core network to the client's premises-as a consequence simply managing VoIP features and maintaining a top trait of adventure (QoE) for the client.

    The system screens key performance and high-quality indicators in precise time, for metrics including utilization (busy-hour convene makes an attempt, minutes of use, and score in palpate with destinations); VoIP first-rate (MOS), cognomen readability index, and speech endeavor); cognomen signaling (name completion cost, grade of provider, and post-dial extend); provider first-rate (availability, reecho lengthen, and establish up-dial delay); and subscribers (normal earnings per person, condition of carrier events, and open tickets), as shown in determine 1.

    A 2d Tivoli answer, the Netcool commercial enterprise VoIP manager, consolidates the administration of VoIP applications, servers, and the underlying networking infrastructure, from PBXs to gateways. This gadget is designed to meet the necessities of each medium and massive firms-as well as managed provider providers.

    This providing is packaged with the Tivoli Netcool OMNIbus and Tivoli Monitoring products, and allows community managers to extend their existing monitoring capabilities to the administration of VoIP technologies. This respond can scale to assist business environments of as much as one hundred,000 IP endpoints, and offers out-of-the-container aid for each Cisco and Nortel VoIP environments.

    For Cisco environments, the commercial enterprise VoIP supervisor helps Cisco cognomen manager and Cisco cohesion, plus facet routers, gateways, and gatekeepers. For Nortel environments, the product supports communique servers, business communication managers, media gateways, faraway gateways, and signaling servers.

    The system comprises true-time shows with numerous charts that demonstrate community utilization, ability, availability, and performance metrics, plus customizable historical experiences. it's designed to operate with purple Hat enterprise Linux, Microsoft windows Server, or Microsoft home windows XP expert operating techniques.

    developing a VPN Gateway | real Questions and Pass4sure dumps

    A virtual inner most community (VPN) is a device that permits the relaxed transmission of facts over untrusted networks such as the web. VPNs commonly are used to relate local enviornment networks (LANs) into wide enviornment networks (WANs) using the web. possibly you necessity to build a VPN between two offices however don't seem to be certain if the substantial infrastructure fees linked to an enterprise-level VPN solution are justifiable. The efficiency of functions which are meant for utilize over LANs (as an specimen folks that utilize community file sharing) severely will also be degraded over WAN connections. Likewise, decrease bandwidth and longer latency in WAN connections can bask in an consequence on adversely the reliability and performance of groupware and skinny-customer purposes. perhaps you bask in got a house office and would relish to utilize your high-speed cyber web access to relate seamlessly and securely to your workplace LAN through an IPSec-competent router. Or possibly you are only interested in VPNs and IPSec in regular and want to test.

    The VPN firewall mentioned listed here will race on virtually any 486-or-more desirable workstation that has 16MB or extra leading reminiscence and two Linux-compatible Ethernet community playing cards. The thought is to provide a starting point from a single, self-contained package for you to permit you to create robust, cozy, scalable and extremely configurable VPNs that are also interoperable with many regular commercial VPN implementations. if you necessity to experiment on a low-renovation firewall-VPN gateway, then the rig discussed here should be would becould very well be ultimate for you.

    this article indicates you how to set up, at minimal rate, a working VPN gateway that makes utilize of the IETF's (web Engineering assignment drive) IPSec (information superhighway protocol safety) specification. IPSec is an open household and is supported via practically outright most distinguished firewall utility and hardware companies, such as Lucent, Cisco, Nortel and investigate factor. This kit will give you a commonly interoperable IPSec that makes utilize of the de facto accustomed 3DES encrypted, MD5-authenticated web page-to-website or factor-to-website VPN. be confident to be capable of accomplish that with out resorting to a full Linux distribution or recompiling a gauge Linux kernel with a kernel IPSec module.

    The VPN device they assess here is according to FreeS/WAN (, a conveyable, open-source implementation of the IPSec specification. FreeS/WAN has been confirmed to interoperate, to a number of levels, with Cisco IOS 12.0 and later routers, Nortel Contivity Switches, OpenBSD, Raptor Firewall, verify point FW-1, SSH Sentinel VPN 1.1, F-at ease VPN, Xedia entry element, PGP 6.5/PGPnet and later, IRE SafeNet/SoftPK, Freegate 1.three, Borderware 6.0, TimeStep permit/Gate 2520, Intel Shiva LanRover, sun Solaris and windows 2000. The reputable FreeS/WAN net site has a frequently updated compatibility list with the latest version of its online documentation. FreeS/WAN edition 1.5 is covered in this kit.

    I actually bask in created a single-diskette distribution that installs the basis configuration of a VPN firewall based on the Linux Router undertaking (LRP,, a compact Linux distribution that can well on a single, bootable floppy diskette. The distribution privilege here is pretty much Charles Steinkuehler's Eiger disk picture with Steinkuehler's IPSec-enabled kernel and LRP IPSec equipment. Firewalling is carried out through Linux ipchains. This selected edition is in accordance with the 2.2.16 kernel of Linux. This distribution is called DUCLING (Diskette-based mostly ultra Compact Linux IPSec community Gateway). Compact Linux distributions bask in a twisted history. LRP technically refers to Dave Cinege's compact distribution. there are lots of variations around, including Charles Steinkuehler's distribution (EigerStein) of Matthew grant's defunct Eiger version (lrp1.steinkuehler.internet). a different such distribution is David Douthitt's Oxygen ( home page?menu=900&page_id=1). also, there's LEAF (Linux Embedded appliance Firewall), a developer's umbrella that tries to coordinate releases and documentation, contour of relish a one-cease shop for compact Linux distributions (leaf.sourceforge.web). i buy advantage of the time epoch LRP to check with the compact Linux distribution offered here, however some may additionally consider this terminology wrong.

    when you are operating MS home windows 9x, the distribution self-extracts and installs itself onto a gauge 3.5", high-density floppy diskette. You can also write the photograph to a boot floppy if you bask in a gadget working Linux. as soon as the extraction is done, you're going to should boot off the floppy disk you bask in got created, reproduction the network drivers in your community playing cards over and edit the arrogate configuration data. it is it—no growing and formatting disk partitions or messing with boot managers in your tough power. if you are not satisfied with the distribution, simply pop the diskette out, pitch it away (or reformat it) and reboot your computing device. examine the links on leaf.sourceforge.internet/devel/thc for more suggestions on these options.

    background on the Firewall and the VPN

    This distribution of LRP uses a gauge ipchains-based mostly firewall. ipchains (changed via iptables within the 2.four sequence kernels—see David A. Bandel's “Taming the Wild Netfilter”, LJ, September 2001) is a freely dispensed packet filter for Linux. It is awfully instructive to seem through the ipchains HOWTO if you don't seem to be household with this firewalling tool. This will also be discovered at

    The VPN is supplied by means of FreeS/WAN's implementation of IPSec. FreeS/WAN's IPSec implementation is compliant with the IETF's IPSec specification. IPSec is an extension to the internet Protocol (IP) that offers for authentication and encryption. Three protocols are used to wield encryption and authentication, namely ESP (Encapsulating security Payload), AH (Authentication Header) and IKE (the cyber web Key trade). outright these accessories are covered in the FreeS/WAN implementation of IPSec and usually are limpid to discontinuance clients. ESP and AH deal with encryption and authentication, while IKE negotiates the connection parameters, including the initialization, coping with and renewal of encryption keys. The simplest encryption scheme at present supported by FreeS/WAN is 3DES (the triple DES or statistics Encryption typical—the latest de facto common for IPSec encryption). Authentication is conducted the usage of MD5 digests of a so-called shared surreptitious (a shared key). The shared key generally is a jointly agreed-to personality string, RSA cryptographic key pairs or X.509 certificates. FreeS/WAN's KLIPS (kernel IPSec) part, which is compiled into the Linux kernel, implements AH, ESP and the managing of packets. IKE procedures wield key negotiation, and renewals are carried out in FreeS/WAN's standalone pluto dæmon.

    requirements and installation

    First, you're going to necessity a pc with a floppy disk power (I even bask in demonstrated simplest 3.5" disk drives) and two community cards in it. The calls for of LRP (the distribution) are minimal and don't require a powerful notebook. anything else that is Intel 486-type or better with greater than 8MB of RAM will do. You additionally will want two floppy disks. authentic, excessive-density three.5" floppy disks should soundless do, equivalent to promotional diskettes from AOL. I even bask in never had any issues with prevalent floppy disk drives, however I actually bask in establish some issues with writing the distribution to floppy disks with Imation USB U2 SuperDisk drives.

    you will deserve to down load the arrogate DUCLING.tgz/zip distribution from and extract the contents of the archive file. in case you bask in a static IP address, then download the static version, and when you are assigned a dynamic IP address, you are going to want the distribution with a DHCP customer. if you're operating home windows 9x, download or Extracting the .tgz file with Winzip ( will produce a file, ducling-dyn-1-0.exe or ducling-stat-1-0.exe and listing modules. The .exe file is a self-extracting photo that codecs a floppy disk and writes the photograph to that disk. race the ducling-stat-1-0.exe or ducling-dyn-1-0.exe file and plot a floppy disk into the floppy disk drive. notice that any facts on the disk will be overwritten.

    if you are the usage of MS-DOS or home windows 3.1, the TSR utility FDREAD.EXE must be loaded on the DOS plane first if you want to read and write to the 1,722KB structure disk. FDREAD.EXE is a freeware application from Christoph H. Hochstätter.

    if you are running Linux, down load ducling-dyn-1-0.tgz or ducling-stat-1-0.tgz, untar the photograph (the specimen here is for the DHCP-enabled dynamic IP tackle distribution):

    tar xvfz ducling-dyn-1-0.tgz

    and write the vivid file, ducling-1-0.img, to a formatted floppy the usage of the Linux fdformat and dd commands:

    fdformat /dev/fd0u1722 dd if=ducling-dyn-1-0.ima of=/dev/fd0u1722 as soon as the floppy disk picture is created as outlined above, you can bask in a bootable Linux floppy diskette.

    The zipfile/directory named modules accommodate the required community driver modules as well as not obligatory modules for firewall masquerading. copy the contents of the module zipfile or directory onto a divide second MS-DOS-formatted floppy diskette for the configuration portion of this dialogue (below). In Linux, structure a 2d floppy disk by means of running

    fdformat /dev/fd0

    adopted through

    mkdosfs /dev/fd0 and mounting the floppy oblige and copying the modules over. examine the documentation included in the README data, with the intention to provide you with details on configuring your firewall/router.

    if you are unable to well the entire favored applications and modules onto a single floppy diskette, you are going to should verify choice setups that utilize dual floppy diskettes (see the covered README files with the DUCLING distribution), a bootable CD-ROM or even a petite complicated disk. parley with the on line sources of LRP documentation for further guidance.

    The LRP Boot Floppies—The magnificent actuality

    You can be stunned to discover that LRP uses DOS-formatted floppies. You can be much more stunned to find that the DUCLING distribution installs itself as a 1,722KB bootable disk image. The three.5" high-density floppy is technically a 2MB format medium, and you can espy these diskettes rated as 2MB “raw” or “unformatted” capability. The 1,440KB formatted potential is basically the consequence of a conventional structure that writes eighty tracks on the magnetic media with 18 sectors per track. With the arrogate equipment, which you can create diskettes which bask in 80 sectors and 24 tracks per sector, giving 1,920KB per floppy. Floppies having 1,680KB (eighty/21 sector/tracks per sector) are used constantly for LRP distributions and issue to bask in a legitimate track list; 1,722KB (eighty two/21), 1,743KB (eighty three/21) and 1,760KB (80/22) also are suggested to be in use. I bask in establish the 1,722KB structure floppy to be official enough for checking out and haven't any problems to report to date.

    I bask in created and used huge-structure floppies of up to 1,920KB. extremely giant-layout floppies are typically nonbootable, apparently as a result of a fight between pc BIOSes and the nonstandard sector dimension on the diskette. It has been said that gigantic-structure floppies higher than 1,680KB can suffer from floppy disk hardware dependability problems. windows NT and windows 2000 are reported to bask in reliability issues writing to massive-format floppies bigger than 1,680KB.

    MS windows 9x operating programs frequently read common in addition to giant-format floppy diskettes with no configuration adjustments. In Linux systems, it is frequently crucial to mount the floppy disk with the proper layout designated, i.e., /dev/fd0u1722, where fd0u1722 specifies floppy disk machine 0 (fd0) and the u1722 specifies a 1,722KB format. The commonplace floppy disk drive in Linux /dev/fd0 defaults to /dev/fd0u1440, the 1,440KB structure.

    For growing and manipulating large-structure floppies, talk to the LRP Boot Disk HOWTO by Paul Batozech. you are going to find this, and different valuable articles, in the supplies listed at leaf.sourceforge.web/devel/thc. For MS home windows, I actually bask in establish Gilles Vollant's WinImage ( to be specifically positive and user pleasant. however, it is in some ways extra constrained than the Linux equipment, akin to fdformat, mkdosfs and the greater fresh superformat application. The self-extracting 1,722KBps photographs for MS windows mentioned privilege here had been created the usage of WinImage.

    How the LRP Distribution masses

    earlier than you start to travail with LRP it is constructive to word how the distribution works. if you assess the bootable diskette, you're going to espy a sequence of files, together with ldlinux.sys, linux, syslinux.cfg, root.lrp, and so forth.lrp, modules.lrp and local.lrp.

    The file ldlinux.sys is the bootstrap loader that loads the kernel (the file named linux) and introductory root.lrp kit into reminiscence. The kernel begins and creates a RAM disk and extracts the basis.lrp kit. A RAM disk is a component of reminiscence it really is allocated as a partition. In different phrases, the kernel creates an zone in recollection and treats it relish a read/write disk. The kernel then mounts the boot gadget designated in syslinux.cfg. The closing .lrp packages on the boot disk are extracted as targeted in syslinux.cfg and loaded to the RAM disk. The .lrp programs are in simple terms common UNIX tarballs (tar-gzipped archives). once the .lrp programs are installed in the directory tree on the RAM disk, the system starts off a boot based on the common Linux rc file boot hierarchy.

    LRP is effortlessly a stripped-down typical Linux kernel with loadable modules and different software contained in units of .lrp packages. LRP is basically Linux; commonly, anything with a view to race on a commonplace Linux distribution should soundless race off the LRP diskette. regularly the impediment to extending LRP's functions and capabilities is the zone constraint of a single diskette. in case you require additional capabilities, as an instance, remote administration through ssh, a DNS server and so on, you will necessity to study multidiskette, CD-ROM and even the entire disk drive distributions of LRP that can be found.

    birth up and Configuration of Router/Firewalling VPN

    as soon as the bootable floppy disk is created, contour confident the floppy is placed in the floppy disk drive of the computer on which you want to race the firewall/VPN. ensure that the BIOS is configured to boot from a floppy disk. Upon booting the firewall/VPN, you're going to espy the LRP splash monitor, messages from the Linux loader followed with the aid of a login on the spot.

    when you've got made it this some distance, congratulations! you bask in installed an LRP distribution efficaciously. Now which you can start to configure the firewall homes of the LRP as outlined within the bundled documentation.

    as soon as any firewalling tweaks are completed, the VPN must be configured. The bundled DUCLING documentation discusses the particulars for configuring a subnet-to-subnet setup. This comprises configuring IPSec's authentication mode (/etc/ipsec.secrets), the IPSec network configuration (/etc/ipsec.conf) as smartly as the firewalling rules to enable access to ports 500 (UDP), 50 and 51 (TCP).

    word that you needn't necessarily require a static IP tackle with the intention to race VPN hyperlinks. A “roadwarrior” configuration is described within the subsequent area, by which the one VPN customer has an undetermined static IP tackle. I bask in race VPNs between pairs of nodes with dynamically assigned IP addresses. The administration of VPN nodes with DHCP-assigned IP addresses becomes intricate if each IP address assignments trade generally. privilege here zone discusses a roadwarrior configuration the usage of DUCLING and a Microsoft-based mostly IPSec customer.

    Interoperability example

    This instance shows an MS windows 9x/2000 customer element-to-site using SSH Communications safety Sentinel 1.1 (Public Beta 3). FreeS/WAN is interoperable with a substantial orbit of IPSec implementations. the convenience of implementation and computability will orbit counting on the product. Many IPSec items that aid 3DES/MD5 encryption through IKE are interoperable with FreeS/WAN. despite the fact, I establish that legally acquiring entirely purposeful IPSec implementations that guide strong encryption can also be exhausting, especially in case you are animated backyard of the united states.

    Many companies offer best confined capabilities of their freely purchasable IPSec implementations. as an example, a product may additionally handiest advocate frail encryption (DES) or can also restrict VPN capabilities to transport mode only. it is vital to differentiate between the two VPN modes that are offered through IPSec: transport mode and tunnel mode. Transport mode encrypts and authenticates site visitors between two mounted discontinuance features. Tunnel mode is more beneficial for connecting subnets and allows for tunneling through firewall and router parameters into different subnets. in reality, transport mode restricts site visitors to factor-to-point verbal exchange. Tunnel mode additionally permits aspect-to-web site (aspect-to-subnet) or web site-to-web page communications. as a minimum one dealer doesn't issue to enable its implementation of IPSec to race over a connection the utilize of a static IP tackle.

    The SSH Communications protection Sentinel product ( does not issue to endure from any of these issues, probably due to the fact that the business is primarily based outside of the U.S.. I downloaded and confirmed the 30-day visitation beta three liberate of Sentinel 1.1 and located it to be very effortless to configure on a windows 98 desktop computing device. The Sentinel documentation offers configuration examples for interconnectivity with a FreeS/WAN VPN gateway.

    here is a summary of a roadwarrior configuration that allows for faraway clients with dynamically assigned IP addresses to relate transparently to a LAN behind a firewall. you are going to should open ports 50, fifty one (TCP) and port 500 (UDP) to the dynamic IP tackle or the ISP's DHCP tackle latitude. pattern 1 indicates the basic setup. you are going to necessity to edit /and so on/network.conf on the DUCLING FreeS/WAN firewall (go into lrcfg, choose 1), then 1) and set


    to disable the blocking off of tunneled packets. The bundled documentation includes the exact instructions on a artery to accomplish these initiatives.

    determine 1. A Roadwarrior-to-site Configuration

    The contents of the FreeS/WAN ipsec.conf file are given in list 1. The corresponding ipsec.secrets and techniques file consists of the entry

    1.2.three.4 PSK "Put your roadwarrior mysterystring privilege here"

    the plot the phrase in fees is a shared-secret string. The IP wield denotes any IP address, so recall to select a comfy shared-secret string. The rightsubnet and rightnexthop parameters are left antiseptic and imply that the connection is some extent-to-subnet connection.

    checklist 1. The FreeS/WAN conn listing for the Setup proven in pattern 1.

    To installation the Sentinel IPSec carrier:

  • down load SSH Sentinel from and installation, following the instructions.

  • Go into the Sentinel coverage supervisor (determine 2).

    determine 2. Sentinel coverage supervisor

  • select the distinguished thing management tab, Authentication Keys and choose Add (determine 3).

    figure three. including a brand new Key

  • opt for Create a brand new preshared key then next (determine 4).

    determine 4. Configuring Preshared Key

  • type on your preshared key. It bask in to be identical to the shared-secret string you bask in inserted in /and so on/ipsec.conf (devoid of the charges). (See pattern 5.)

    determine 5. Typing in Shared Secret

  • Press conclude.

  • On the leading console of SSH Sentinel policy supervisor, within the security policy pane, select VPN connections®Add.

  • Enter in the IP/hostname of the faraway VPN gateway; for their illustration, it's 1.2.three.4, and choose the preshared surreptitious that you created in step 5 because the Authentication key (determine 6).

    figure 6. entering Key and UP information

  • choose 3DES encryption, main Mode and MODP 1024 for IKE Mode and IKE group, respectively. The superior pane generally will also be left with the defaults.

  • Set the IKE SA lifetime (i.e., the interval between rekeying) to the identical cost as within the ipsec.conf file, customarily 480 minutes (eight hours).

  • save outright settings and try to ping an internal node at the back of the firewall (try the inside interface, 192.168.x.254). you'll want to be related. try working Sentinel's diagnostics to contour certain you are linked. I even bask in discovered that Sentinel's diagnostic mode can dangle the FreeS/WAN-home windows connections sometimes. If this occurs, bound to the FreeS/WAN gateway and accomplish a restart of IPSec after which bring up the numerous connections.

    determine 7. The VPN Connection homes Tab

    once once more, if you deserve to restart the connection, log in to the LRP container and type

    #/and many others/initd.d/ipsec restart

    to restart the IPSec components.

    I also establish in home windows 2000 knowledgeable (however no longer home windows 98) that I needed to add the routing manually to the shared subnet from the DOS console:

    route ADD mask 1.2.three.4

    (consult with the documentation for the Microsoft route command).


    this article outlines the skill to establish in oblige a firewalling VPN gateway from a single 3.5" floppy diskette. With a single floppy diskette, you should definitely be able to connect hosts and networks of a lot of topologies securely the utilize of the information superhighway. The DUCLING distribution is a bare-bones distribution. when you are convinced that a FreeS/WAN VPN can fulfill your wants, you can examine either going to a greater full-featured LRP distribution or even a full-blown Linux gadget, implementing such things as far flung entry (by means of the relaxed shell, ssh, for instance) or a DNS server.

    AMD's Ryzen Embedded R1000 train SoC brings Zen performance to low-power market | real questions and Pass4sure dumps

    AMD's newest embedded SoC competes with Arm-based systems for digital signage, microconsole, and other low-end platforms.

    AMD is taking a second shot at the embedded market with this week's introduction of the Ryzen Embedded R1000 SoC (system-on-a-chip) series, which are touted as being compatible with AMD's existing (and comparatively higher-power) V1000 train platform. The Ryzen Embedded R1000 train are built on 14nm Zen and Vega cores, targeted for a TDP of 15-25W.

    Two variants of the R1000 train were announced, both with a two-core, four-thread design—the key differentiator here being clock speeds. The R1505G runs at 2.4 GHz basis / 3.3 GHz turbo speed, while the higher-power R1606G runs at 2.6 GHz basis / 3.5 GHz turbo speed. The Vega GPU cores race at 1 GHz on the R1505G, and 1.2 GHz on the R1606G. full benchmarks are available at 3DMark—oddly, from October 2018.

    AMD is positioning the pair as having "3x generational performance improvement per watt, and 4x better CPU and graphics performance per dollar than the competition," which in this case is an Intel Core i3-7100U.

    SEE: Hybrid cloud: A guide for IT pros (free PDF) (TechRepublic)

    The R1000 train advocate up to 4K displays at 60 FPS, via DisplayPort 1.4 connections, with hardware-accelerated H.265 encode/decode and decode for VP9. The duo also integrate two 10GbE connections, and advocate the same security extensions establish on server-targeted EPYC CPUs, making the duo attractive for NAS and digital signage utilize cases.

    Atari is planning to utilize the new CPUs for the Linux-powered Atari VCS microconsole, in plot of the originally announced (and lower-power) AMD APU, and they are expected to issue in other (not necessarily consumer-facing) embedded systems for digital signage and embedded systems in the near future. The R1000 would be an attractive option for a higher-end single board enthusiast computer, as the x86-64 architecture and UEFI advocate allows for easier deployment than Arm-powered devices.

    Improving Server Performance | real questions and Pass4sure dumps

    Looking to help the performance on your high-end Linux server? Is your Linux system connected to a high-speed network? Are your servers spending too much of their resources on processing the TCP/IP stack and Ethernet frames? These are just some of the problems in today's network environment. These problems arise because TCP/IP traffic on the Internet and on private enterprise networks has been growing dramatically for the past decade, and there is no mark that growth will be slowing down any time soon. The widespread global adoption of the Internet and the evolution of new networking storage technologies such as iSCSI are driving networking speeds even faster. Although the processors being manufactured today are gaining accelerate at an astonishing pace, it is likely that network-related growth will continue to outpace the increasing processor speeds, slowing servers from their primary tasks to process network packets.

    Intel has developed a prototype that offloads an entire TCP/IP stack from a Linux-based operating system onto an intellectual network interface card (iNIC).

    The iNIC Design

    The iNIC contains a real-time operating system (RTOS) and an entire TCP/IP version 4 stack. An I/O processor (IOP) on the iNIC processes outright of the network packets allowing the host processor to process other tasks. To accomplish this division of labor, a thin layer of logic is needed on the host side to route outright the network traffic through the iNIC.

    Socket Offload

    This technology is based on the intellectual I/O (I2O) architecture, which is already incorporated into the Linux 2.4.x kernel. pattern 1 is an I2O primer for those who are not familiar with I2O. The I2O specification is a message-based communication mechanism between a host operating system (OS) and I/O devices that are sitting on an IOP. The IOP runs an intellectual RTOS (IRTOS), which contains device-driver modules (DDMs) for each connected device. To obtain portability, I2O uses a split-driver model. The specification defines a set of abstract messages for each supported device class (i.e., LAN, tape, disk). The host OS uses the distraught message layer to communicate with DDMs running on an IOP. The DDM translates these I2O messages to hardware-specific commands. To communicate with an I2O device, the host OS must bask in a driver that knows how to translate OS device commands to I2O device class commands. This module in the host OS is referred to as operating system module (OSM).

    Figure 1. I2O Architecture

    The solution is based on an extension of this architecture with the creation of the socket class. Changes were made to the I2O architecture to extend performance and minimize latencies usually associated with a split-driver model.

    Figure 2. Socket Offload Architecture

    The socket class defines messages needed for communication between the host OS and the DDM. The two drivers, OSM and DDM, communicate over a two-layer communication system. The message layer sets up the communication session, and the transport layer defines how information will be shared. The DDM is composed of two modules: intermediate service module (ISM) and hardware device module (HDM). The ISM provides the full functionality of the TCP/IP version 4 stack. The HDM is the device driver for the iNIC. The socket OSM is unlike any other network device in Linux. household network card drivers are protocol-independent and interface with the Linux kernel at the network application program interface (API). The socket OSM, on the other hand, will interface directly below the socket API. This allows the necessary socket services to be offloaded onto the IOP running the socket class ISM. The socket OSM replaces the services that the TCP/IP stack provided to the kernel, thereby providing necessary interfaces to the Linux kernel. It also transmits and converts socket requests and data in the socket offload format to the iNIC running the TCP/IP offload stack.

    Socket OSM

    The OSM is divided into the following subsystems: user interface, message interface, kernel interface and recollection management.

    The user interface replaces the af_inet socket layer in the kernel. It provides feedback to the users' programs exactly as the autochthonous (non-TCP/IP offloaded) kernel would provide.

    The message interface provides the initialization and control of the socket offload system. It translates the user socket requests to the socket messages.

    The kernel interface provides kernel services to the OSM. This is the point at which the OSM provides any services normally provided to the kernel by the TCP/IP stack. This subsystem was designed to minimize the modifications needed for the Linux kernel.

    The recollection management module provides the buffer pools needed for data transfer to and from the user-space applications. recollection management was designed to 1) minimize the number of data copies and DMA requests, 2) minimize the host interrupts, 3) avoid requiring costly physical-virtual address mappings and 4) avoid overhead of dynamic-memory allocation at runtime. Two pools of DMA-capable data buffers are maintained in the OSM. The transmit buffer contains the data headed for the iNIC; the receive buffer receives the data into the kernel from the socket device.

    Figure 3. Linux TCP/IP Stack

    As shown in pattern 3, Linux network components consist of a layered structure. User-space programmers access network services via sockets, using the functions provided by the Linux socket layer. The socket structure defined in include/linux/net.h forms the basis for the implementation of the socket interface. Below the user layer is the INET socket layer. It manages the communication discontinuance points for the IP-based protocols, such as TCP and UDP. This layer is represented by the data structure sock defined in include/net/sock.h. The layer underneath the INET socket layer is determined by the sort of socket and may be the UDP or TCP layer or the IP layer directly. Below the IP layer are the network devices, which receive the final packets from the IP layer.

    The socket OSM replaces the INET socket layer. outright socket-related requests passed from the socket layer are converted into I2O messages, which are passed to the ISM on the IOP.

    Embedded Target

    The embedded system software consists of the messaging layer, TCP/IP stack, device driver and RTOS.

    The messaging layer is the portion of the software that takes messages from the OSM, parses them and makes the socket convene into the TCP/IP stack. This layer also takes replies from the network stack and sends the arrogate reply to the OSM. To help performance and minimize the effects of latency inherent in split-driver systems, the messaging layer batches, replies and pipelines requests.

    The embedded TCP/IP stack is a zero copy implementation of the BSD 4.2 stack. It provides outright of the functionality of a networking stack to the messaging layer. relish outright the software that runs on the IOP, the stack has been optimized for running on the Intel 80310 I/O processor chipset with Intel XScale microarchitecture (ARM-architecture compliant). Benchmarks were performed on the TCP/IP stack during optimization to ensure that it would fulfill well across outright sizes of data traffic.

    The HDM was written to buy advantage of outright the offloading capabilities of the NIC hardware. This includes TCP and IP checksums on transmit and receive, segmentation of great TCP packets (larger than 1,500 bytes) and interrupt batching supported by the chip. The NIC silicon chips supported were the Intel 82550 rapid Ethernet Mu.pngunction PCI/CardBus Controller and the Intel 82543GC Gigabit Ethernet Controller.

    The RTOS is a proprietary OS that has been designed for the demands of complicated I/O operations. This OS is fully I2O-compliant. It was chosen in piece because of the willingness of the designers to contour modifications to the OS for the prototyping efforts.

    As described before, the socket calls made by the application layer are converted into messages that are sent across the PCI bus and to the I/O processor. This embedded system is a complete computer for performing I/O transactions. It consists of a processor, memory, RTOS and a PCI bus. Because it is designed for I/O, it will minimize the effects of context switching. Once a message reaches the IOP, it is parsed. The socket convene that was requested by the application is then called on the embedded network stack. A reply message is sent to the OSM once the socket operation is completed.

    Benchmark Results

    The benchmark tests that were race using the prototype showed that the offloading of the TCP/IP stack significantly reduced both CPU utilization and the number of interrupts to the host processor. With a heavily loaded machine, the offloaded stack was able to maintain overall network performance and host CPU cycles were able to remain dedicated to the workload applications. In a autochthonous machine, the host processors were interrupted far more frequently, and the network application suffered from CPU resource starvation resulting in the network performance degradation.

    Figure 4. Benchmark Results

    Future Direction

    As the topic of iSCSI (storage over IP by encapsulating SCSI in a TCP/IP packet) starts to heat up, desire for minimizing network overhead will continue to grow. Efforts used in touching the TCP/IP stack to an IOP quickly could shift to providing a full-featured TCP/IP stack at the back discontinuance of an intellectual iSCSI adaptor. This would minimize the repercussion of iSCSI to a Linux platform by making it available via the household SCSI API. To compete with Fibre Channel, iSCSI must provide comparable performance.

    Another future enhancement is that embedded Linux will be used for the RTOS. At the start of this prototyping effort, an Intel i960 RM/RN processor was used, and embedded Linux was not available. Since then, the Intel XScale microarchitecture has been introduced, enabling the adoption of the embedded Linux that is available for Intel StrongARM core. Porting of Linux-based StrongARM Linux to the XScale microarchitecture will be completed by the discontinuance of the year.

    There were several goals behind this prototype effort: 1) to demonstrate that the enhanced performance achieved by offloading network tasks from the host processor reduces the host processor cycles otherwise consumed by processing of network data, 2) to note that the utilize of specialized software on the iNIC performs the same networking tasks while maintaining overall network performance and 3) to enable the utilize of I/O processors to travail in conjunction with the host processors to wield the network traffic, thereby maximizing performance of a Linux-based server at minimal cost.

    Offloading the TCP/IP protocol to a specialized networking software environment using embedded processors is an effective artery of improving system performance. With the advancement of high-speed network deployments and adoption of network storage, TCP/IP will inevitably play an distinguished role.
