Telecoms.com periodically invites expert third parties to partake their views on the industry’s most pressing issues. In this post, Bill Kaufmann, Group Product Manager, SDN Planning at Coriant, explores the benefits of SDN to mobile backhaul networks and looks at best practice for implementation.
Mobile services and mobile backhaul (MBH) networks are under pressure from a variety of technology, market, and pecuniary forces. Bandwidth claim from mobile devices (smartphones, tablets) is exploding, driven by streaming media and real-time communications applications. With LTE-A and 5G mobile user throughputs rising to 1G and beyond, it is becoming increasingly costly to backhaul complete traffic to the network core.
A novel generation of services – and rising end-user property of suffer (QoE) expectations – will breathe far less tolerant of latency and congestion. As novel Over the Top (OTT) applications show with increasing speed, carriers will struggle to respond on short notice to user and service demand. The predicted proliferation of low hurry sensor traffic and network attached devices for Machine nature Communications (MTC) will require ultra-high reliability connectivity to private monitoring facilities rather than traditional mobility gateways.
These trends point to the need for a less hierarchical, more dynamic, and performance-aware mobile backhaul network at a time when pecuniary pressures claim more efficient network utilization, more efficient network operations, and innovative novel services. Fortunately, implementation of Software Defined Networking (SDN) in mobile backhaul networks can wait on meet these challenges.
There are 3 key SDN concepts that covenant substantial benefits in mobile backhaul networks:
Together, the introduction of an external control plane and programming APIs, on top of a robust network infrastructure, will enhance backhaul configurability and optimization to ameliorate flexibility and responsiveness of the mobile network.
These concepts point to a several set of lead SDN applications for mobile backhaul networks.
Improved Network Utilization and Operation. Excess capacity is commonly provisioned in MBH networks in the shape of protection links in case of network outages. In addition, equable condition network traffic usage is often capped at 60-70% of total link capacity to accommodate bursty traffic patterns. This combination of design criteria leads to networks operating at only 30-40% of potential capacity. With SDN, novel network optimization policies such as re-routing bursty traffic to alternate paths based on congestion, or making expend of protection paths to accommodate unpredicted bursts, can breathe enforced.
Today’s mobile networks were designed to direct complete traffic to a central core, but as traffic patterns change and pass between cell sites, and as virtualized services supersede static gateways, more efficient traffic distribution to local handoff points can reduce network load to the mobile packet core. Coriant analysis has estimated that more flexible bandwidth allocation in response to application-driven traffic requirements can generate total mobile backhaul capital expenditure savings of up to 35%. Moreover, by presenting a simplified network view to higher-level management tools, the operating cost and complexity of defining novel services and building connectivity to novel carrier services is significantly reduced.
Operating expense benefits from SDN will breathe achieved through a streamlined network management and control environment.
Automated S1 Interface Provisioning, Re-homing, and Optimization. The S1 interface from cell site to Evolved Packet Core (EPC) is the most fundamental LTE interface. Today, this link is typically configured once and left in place. Manual input by network administrators is generally required for novel service configuration or updates. Granular service configurations and circuit mappings must breathe input via cumbersome command line interface (CLI) or other legacy management protocols (e.g. SNMP). Processes involving multiple configuration and management systems are difficult to adapt to novel services, and impose long service activation cycles. Optimizing in-production services poses an even greater challenge.
With SDN, this static deployment model can change to streamline operations and accommodate future virtual network designs and IoT services. A dynamic path control plane can automate S1 activation to virtual gateways, revolve on diminutive cells as needed based on network usage, and optimize the S1 path in existent time based on network performance, alarms, or congestion from other sites and applications.
More broadly, SDN automation can ensure optimal routing to maintain QoE across mobile backhaul and fixed-mobile converged networks and can breathe linked to on-demand service delivery.
Network uphold for Distributed Virtual Gateways (Smart Mobile Cloud). In the dynamic network of the future, instead of directing traffic to one central gateway, a mingle of virtual resources (EPCs, ADCs, security gateways, etc.) will breathe available on demand, just as virtual servers are activated in data centers today. Virtual appliances will breathe distributed to more effectively cover urban metro areas, rural communities, enterprise customers, or dedicated IoT applications.
To uphold this dynamic environment, access and aggregation networks must adapt in existent time to provide connectivity on the sail as virtual resources are activated. SDN-based network automation is required where destination routing using static MPLS tunnels does not provide sufficient flexibility. Using SDN, discontinue user traffic can breathe re-homed toward newly activated resources, or diverted to available capacity for load balancing.
As L4-7 functions (e.g. firewalls, NAT, DPI, load-balancing, etc.) drag to virtual platforms, SDN can activate connectivity on-demand to novel service instances. Ultimately, the growing distribution of services throughout metro networks will lead to smart IP/MPLS and virtual appliances at the edge, and a multi-layer, multi-domain SDN control structure to uphold a dynamic novel service environment.
Mobile backhaul networks are on the cusp of major re-design to uphold next generation wireless services. SDN promises to win this transition viable along with improving utilization and user property of experience. While these benefits are alluring, in practical terms SDN will breathe implemented in networks with great amounts of legacy equipment. The migration of legacy networks to SDN control is perhaps the most captious technical challenge for service providers.
With the significant capital investment and operational complexity ingrained in existing MBH networks, network planners must carefully evaluate different approaches to SDN as they undertake initial rollouts over the next 2-3 years. Having a pellucid understanding of the highest potential applications for SDN in MBH, as well as developing consistent criteria for solution evaluation, will breathe essential to gain maximum capitalize from these initial deployments.

The novel WCAU-WWSI facility, set for a stately opening sometime this fall, is IP-centric and is designed to not only give the two stations a more efficient space with a common technology infrastructure, but to give their personnel novel flexibility in creating content for today’s multiplatform world.by Glen Dickson October 11, 2018 11:23 EST
The first thing you notice when entering Studio A at the new, state-of-the-art facility where NBCUniversal Owned TV Stations Division’s WCAU Philadelphia newscasts will soon breathe produced is an gargantuan cityscape behind the anchor desk.
Measuring 20 feet across by 10 feet high, the image is not unlike those on many TV stations these days. Except that on this one, flags are poignant in a slight snap and the water of the Delaware River is flowing by on a gray, overcast day.
“It’s a 4K LED monitor which will broadcast 4K video from a 4K camera,” explains Ric Harris, president and common manager of NBC10 and sister station WWSI (Telemundo62). “It’s going to give us the best skyline shot of Philadelphia.”
The facility, likewise home to WWSI, offers Great views from any of its windows. It’s located on three floors (12-14) of the 60-floor, 1,121-foot Comcast Technology center in downtown Philadelphia.
Inward from Studio A, you can gape across a glass enclosed, two-story atrium to observe a similar studio — just steps away — where the WWSI anchors will sit in front of another, only slightly smaller, 4K monitor.
An open staircase just outside the entrance to Studio A descends to a large, open newsroom, flooded with daylight from the atrium’s main wall, where reporters and producers from both stations drudgery together.
But the existent marvel of the set may not breathe the architecture and interior design, but the cutting-edge fibered-linked IP infrastructure at its core.
The open newsroom
“I didn’t want to breathe restricted by traditional SDI routers, and I wanted the aptitude to retain video coming in and hold it fade anywhere else in the plant,” says Tony Plosz, WCAU-WWSI VP of engineering and operations.
“I likewise wanted the flexibility so that staff could expend any system, and drudgery anywhere across the floors, or even in the field. The ‘anywhere, anything’ philosophy was really huge in the design.”
Having originally planned to launch in late 2017, NBCU has been letting its 2018 launch date — now set for sometime this tumble — quietly slip as engineers drudgery to finalize software and staff gets up to hurry on updated platforms.
“We are using the latest versions of the technologies they hold installed, and they are working now to win sure everything works together as it should,” Harris says. “We will launch when they know it’s right.”
The stations’ sales, traffic, finance and human resources departments have already moved in and news, creative services and engineering staff hold been splitting time between the novel space and the existing station in suburban Bala Cynwyd, which will eventually breathe vacated.
“It’s been a long road, and enjoy any other large-scale project, we’ve made changes along the way,” says Plosz. “It’s been a lot of fun, seeing a concrete slab revolve into functioning office space.”
Integration And Connectivity
Comcast Technology center is shun by NBC parent Comcast and existent estate investment faith Liberty Property Trust. Besides the stations, the other primary tenants are Comcast and a Four Seasons Hotel, which occupies the top of the building.
LF Driscoll is the common contractor of the building with Diversified handling the technical integration for the broadcast facility.
The broadcast facility will accommodate about 180 employees. An additional 60 employees, such as photographers and reporters, will mostly stick to the field.
The drag into the novel facility is allowing NBCU to further integrate WCAU with WWSI, which it acquired in 2013. “We’re taking it another step further here, and they are truly on the identical platform,” says Plosz. “They hold identical control rooms, the identical technology in the studios, everything is the same. Before, so much was retain together on the fly, while here they start from complete scratch.”
Another of the goals is to better integrate broadcast and digital production. Reporters, producers and anchors working on a exhibit collect at a pod — one of several long narrow black tables topped by black monitors — where they can collaborate as they come by closer to air. Steps away is the digital pod for both stations, and immediately behind that is the assignment desk.
“It’s complete connected,” Harris says. “Weather, exhibit pods, digital, assignment desk — all within steps of walking to one another.”
The open floor concept contrasts with the chopped-up configuration in Bala Cynwyd where Plosz says “everybody was in their own slight corner or section. There’s no hunting for someone, complete the core groups are on 12.”
Nestled next to Studio A — and a few feet away from a reception desk — is Harris’ office. “This is a microcosm of what the station is about,” he says. “There is a sense of connectivity. My office isn’t off in the hinterlands. I’m centrally located so I hold access to their folks and the team has access to me.”
There are three studios. The 2,600-square-foot Studio A for WCAU, a 2,400-square-foot studio for WWSI and a 1,500-square-foot auxiliary studio with a great green screen that covers the entire rear wall, giving the station the break to enact plenary virtual set operation in the future.
Plosz sees that third studio as a “really flexible space” that will breathe used for special intelligence segments as well as being employed by creative services to produce commercials for local advertisers.
The 13th floor houses back-office functions including sales and traffic as well as executive offices. The 14th floor contains the finance and human resources departments, a great conference scope and the Central paraphernalia scope (CER), which represents the technical guts of the facility.
IP At The Core
The routing core is a Cisco 100-gigabit Ethernet “Fabric for Media” architecture that links to Grass Valley IPG (IP gateway) cards, allowing the stations to purchase video and “route it via IP to wherever it needs to go,” says Engineering VP Tony Plosz.
When the stations did the technical design 2.5 years ago, Plosz opted to fade with an IP routing core. But at that point the SMPTE 2110 measure didn’t yet exist, and vendors at the 2016 NAB exhibit were mostly talking about supporting the IP transport of content instead of actually doing it.
“When they did the proof of concept with Diversified in Atlanta, it was slight different than traditional TV stations they had done,” says Plosz. “There were a lot of things that didn’t exist.”
Since he couldn’t design a completely IP operation in 2016, Plosz opted for an IP core, with no traditional SDI router, but “off-ramps to SDI” throughout the stations’ operations. The routing core is a Cisco 100-gigabit Ethernet “Fabric for Media” architecture that links to Grass Valley IPG (IP gateway) cards, allowing the stations to purchase video and “route it via IP to wherever it needs to go,” says Plosz.
“When they first started this endeavor, they didn’t know who was making what,” says Plosz. “There was [SMPTE] 2022-6, and 2022-7, but they didn’t know what would breathe compatible. Over the course of two years the design changed, as even more things went native IP.”
For example, in that time Ross Video’s graphics went from “SDI islands” to direct IP, he notes.
The Cisco routing switches are configured in a traditional spine-and-leaf architecture, says Plosz, with distributed routing across the entire central paraphernalia room. That allows the station to easily plug in novel paraphernalia to the top of a rack and cuts down on overall cabling. There is no need to shun cable to one back row, as the entire router is distributed across mulitple rack rows.
When Plosz began looking in 2016 at broadcast vendors to uphold the IP infrastructure, he quickly narrowed the choices to Grass Valley and Evertz and eventually settled on Grass Valley.
At that point Evertz already had some great IP installations at major broadcasters enjoy ESPN, using its proprietary ASPEN video-over-IP transport protocol.
“They did so well before there were any standards created — they were poignant IP packets and they had some age product,” says Plosz. “But what was the incompatibility between that and a traditional SDI router? They were poignant IP video around, but it was still done through their own switch, and you couldn’t drag other data through it. Did I really want to supersede one proprietary router with another?”
In the end, Plosz thought that Grass Valley had a more comprehensive long-term vision for IP routing and would “be better partners through the science project.”
One of his design criteria was that if the station was going to build its routing on a COTS (common off-the-shelf hardware) switch, it still needed the plenary uphold of whatever traditional broadcast vendor was interfacing with it.
“Grass Valley is their ‘one throat to choke,’ so to speak,” jokes Plosz. “We hold a Great relationship with Cisco, but if they hold any issues, they fade to Grass Valley.”
In addition to the IP gateways, Grass Valley has likewise supplied its LDX 86 studio cameras. Besides Cisco and Grass Valley, other key vendors for the novel facility include Dalet Galaxy asset management, Ross Overdrive production automation, Adobe Premiere nonlinear editing, Lawo audio processing and EMC Isilon solid-state storage.
Fiber, Fiber Everywhere
Being piece of the Comcast enterprise means this novel facility has an incredible amount of fiber-optic connectivity. That is vital when housing a station in a skyscraper, notes Plosz, as he’s not going to set a microwave tower on the roof.
“This building is extremely well connected, and the levels of redundancy here are nothing short of staggering,” says Plosz. “There’s half a terabit per second of I/O in and out of this place, with two complete diverse paths.”
WCAU-WWSI GM Ric Harris
In all, there are 60 miles of fiber in the Comcast Technology center with 1,100 access points. complete the major wireless carriers hold multiple transmitters in the building, says Plosz, and cellphones drudgery even in the “deepest, darkest corner” in the parking garage.
“It’s a phenomenal data system,” he says.
All of the beauty cameras the stations expend around Philadelphia now shun on the Comcast IP network. The facility is likewise converting its studio-to-transmitter link to IP with two physically diverse 100-gigabit fiber paths.
The transmitter site is in Roxborough, northwest of downtown.
“There’s still some microwave gear there, and a slight satellite farm,” says Plosz. “We’re going to extend their Media Fabric over fiber out to Roxborough and win it piece of their [network], an operator here could tug from there and won’t know any difference. They wouldn’t breathe able to enact that without the connectivity they have.”
The novel broadcast facility is designed to breathe one of the most energy-efficient TV operations in the country. It uses heating/cooling and ventilating systems that ameliorate indoor property and reduce noise, and incorporates other green features enjoy capturing natural light from its wall-to-floor windows, water and energy conservation throughout and automated window shades to reduce summer heat. The stations hold likewise tried to expend Energy Star-compliant displays and computers wherever possible.
The stations hold applied for an LEED Platinum certification, which if approved by the U.S. Green building Council, would breathe the first time a local broadcast TV station achieves the Platinum LEED level.
Another unique feature of the Comcast Technology center is the sheer volume of broadcast service panels located throughout the building, including in the lobby, outside on the street, in the cafeteria and the building’s “town hall space,” and in several locations within the Four Seasons Hotel including the ballroom and restaurants on the top two floors.
“We already handle their newsroom as a fourth studio,” says Plosz. “Now the building becomes that fifth studio — there are so many places to easily plug in and fade live.”
