Telecoms.com periodically invites expert third parties to participate 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 exercise for implementation.
Mobile services and mobile backhaul (MBH) networks are under pressure from a variety of technology, market, and fiscal forces. Bandwidth demand 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 trait of sustain (QoE) expectations – will breathe far less tolerant of latency and congestion. As novel Over the Top (OTT) applications loom with increasing speed, carriers will struggle to respond on short notice to user and service demand. The predicted proliferation of low hasten sensor traffic and network attached devices for Machine character 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 fiscal pressures demand more efficient network utilization, more efficient network operations, and innovative novel services. Fortunately, implementation of Software Defined Networking (SDN) in mobile backhaul networks can back meet these challenges.
There are 3 key SDN concepts that swear 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 discrete set of lead SDN applications for mobile backhaul networks.
Improved Network Utilization and Operation. Excess capacity is commonly provisioned in MBH networks in the form of protection links in case of network outages. In addition, constant situation 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 supple 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 pile 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 accommodate 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, spin on minute cells as needed based on network usage, and optimize the S1 path in actual 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 advocate for Distributed Virtual Gateways (Smart Mobile Cloud). In the dynamic network of the future, instead of directing traffic to one central gateway, a merge 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 advocate this dynamic environment, access and aggregation networks must accommodate in actual time to provide connectivity on the flit as virtual resources are activated. SDN-based network automation is required where destination routing using static MPLS tunnels does not provide adequate flexibility. Using SDN, finish 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.) travel 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 bright IP/MPLS and virtual appliances at the edge, and a multi-layer, multi-domain SDN control structure to advocate a dynamic novel service environment.
Mobile backhaul networks are on the cusp of major re-design to advocate next generation wireless services. SDN promises to design this transition workable along with improving utilization and user trait of experience. While these benefits are alluring, in practical terms SDN will breathe implemented in networks with large amounts of legacy equipment. The migration of legacy networks to SDN control is perhaps the most critical 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 lucid 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.

Kyle Sisk knew exactly how his nonprofit organization could accelerate streaming educational video to its subscribers. The only problem was that he couldn't afford it, or so he thought.
Best described as a tiny Netflix for a specialized audience, Described and Captioned Media Program (DCMP), headquartered in Silver Spring, Md., is funded by U.S. Department of Education grants to deal educational video content to K-12 students with visual and/or hearing impairments. But the organization is at the charity of available bandwidth and a wide variety of network issues.
As informational systems manager at DCMP, Sisk wanted subscribers to breathe able to access DCMP's library of 7,000-plus videos without suffering the buffering clique of death that signals network problems. From his background in video production, Sisk knew a content delivery network (CDN) could accelerate distribution by caching videos on servers on the network edge located as near to the user as possible.
Hosting its own glint Media Server in-house for two years, DCMP's IT staff had spent hours dealing with bandwidth constraints and troubleshooting with users to try to deliver video through school firewalls, where DCMP's IP address often wasn't recognized as a trusted provider. That's when the organization decided to gawk at CDNs again.
"We assessed a lot of minute CDN players because they assumed that was complete they could afford," Sisk says, although he moreover contacted cloud-based Limelight Networks, one of the larger CDN service providers, but only to bag a baseline so he could compare it to the prices, services and geographic gain of the smaller players.
"In talking with [Limelight's] sales engineers, they figured out that they could actually afford it. They were shocked, to breathe honest," Sisk says.CDN market grows
DCMP is just one of a growing number of organizations using CDN services to accelerate the delivery of content by caching it locally. And more enterprises are weighing whether CDNs could travail for them.
First created in the late 1990s, content delivery networks were originally the province of the biggest online media outlets, software distributors and e-commerce companies that wanted to deliver content as near to the user's location as possible. At the time, network bandwidth was constrained and latency was high. Akamai Technologies, the oldest denomination in CDNs, launched service in 1999 to address penniless content delivery by placing distributed infrastructure -- often hundreds or thousands of servers -- at points of presence (POPs) or data centers around the world.
Like getting an Amazon order delivered the selfsame day from a local Amazon warehouse, distributed CDN architecture offloads content from the customer and accelerates its delivery by caching a copy and serving it to the user from the POP closest to them. While CDN services weren't cheap, they were a necessity for companies that depended on website performance and availability.
With customer-facing websites now commonplace, the concept of serving content locally is flourishing. Due to the increased expend of video, the growing digital economy and increased cloud services adoption, a number of novel CDN providers maintain launched in the past five years. To compete against established companies fancy Akamai, many target specific types of customers at prices lower than ever before, making CDN services affordable to the many rather than the few.
CDNs typically address three core areas -- software, media and website delivery -- which now moreover includes mobile application delivery, says Gartner CDN analyst Lydia Leong.
Branching out over the years, CDN providers maintain moreover added complementary services that design their value about more than speed. Options embrace distributed denial of service (DDoS) protection, web application firewall services, streaming video platforms, load-balancing, web content optimization and analytics. Some CDNs give customers access to their platforms, allowing developers to expend their application program interfaces (APIs) to add features to their own applications. Others design testing before buying smooth so businesses can contemplate immediately what CDN services can Do for them.
"CDNs maintain gotten more and more economical, and they've become more cost-effective for a broader variety of companies," says Leong. "Since customers are pile applications that reside on the internet, practically any company might potentially maintain need for [a] CDN."
The numbers speak to increasing interest in website acceleration services. In 2015, the global CDN services market generated almost $4 billion in revenue, which represents growth of about 13% over the previous year, according to 451 Research CDN analyst Jim Davis. By 2019, he projects CDN revenue will grow to $6.8 billion.CDN service prices and options
The trick for any enterprise is finding the CDN service that fits its needs at the prerogative price.
Traditional CDN pricing is driven by volume -- the number of viewers, the kick size of the cached content and the number of distributed locations serving it. lofty volume often means lofty discounts. Cloud-based CDN services are usually lower, and the more basic the service, the lower the price.
It helps to start the CDN search process knowing how many objects might need to breathe cached, the middling size of those objects and how many visitors you expect. It's moreover useful to factor in the costs the enterprise already pays to hasten its website to back compare it to the cost of using CDN services. These embrace the obvious storage and server costs, along with less-obvious components fancy the cost of API-driven store look-up features that using a CDN might offset.
Akamai remains the titanic daddy of CDNs, with its own network, intellectual property, customer list that reads fancy a who's who of internet companies, and services for complete CDN market segments. With longevity and 215,000 servers deployed in more than 2,000 locations, Akamai has between 50% and 60% of the market share.
With Akamai's depth and breadth, it may sound fancy other providers should pack up their tents. But customer options continue to grow.
Some CDNs differentiate themselves on the fact that they're not Akamai, pitching themselves as "new and nimble," if smaller. Some serve specific regions; others target minute and midsize businesses, or appeal to developers with their open APIs.
The novel world of CDN competition includes providers fancy Fastly with its API-driven focus; ChinaCache with extensive presence in China; CloudFlare; Amazon's CloudFront; CDNetworks; Yottaa with its mobile performance focus; and Limelight Networks' video services. The list goes on.
A typical Akamai customer often pays from $10,000 per month and up, Leong says, usually not a small-business price. Yet Akamai sells some of its CDN services at lower prices through hosting companies or service providers. The availability of cloud-based CDNs has given accelerated content delivery a boost for companies of complete sizes, however. Cloud-based CDNs aren't as expensive to launch because they're not necessarily buying piles of their own servers. "That means you can start a CDN as if it were a software company," Leong says.
In making their choices, businesses may not breathe of a size to economically expend Akamai, but there are options, Leong says. "Because the cloud is driving novel opportunities, the digitalization of the economy is driving tremendous novel ranges of things that reside on the internet."
Using its cloud services dominance, Amazon Web Services (AWS), as the largest cloud services provider, is driving CDN awareness (and lower pricing models). AWS makes it smooth and affordable for AWS cloud customers by integrating its cloud storage with its own CDN, CloudFront.
While there may breathe reasons to expend a more sophisticated CDN service, AWS's approach is compelling as a starting point, Leong says.
"If you're a startup or other company delivering your online property using AWS, it makes a lot of sense in many cases to expend Amazon's CDN," she says. "Amazon makes it easy, so more people can, in a sense, play with it to contemplate if it works for them."Testing, testing, testing
The faculty to test CDN services in actual time and contemplate the immediate inequity a CDN can design -- or not -- may breathe the strongest selling point for growing CDN adoption. Rather than conducting a huge request for proposal, customers can just try a CDN and contemplate what happens, Leong says, adding that SMB-focused CloudFlare lets users badge up and expend it without paying anything upfront.
"We always recommend that customers gawk at CDNs by actually trying them to bag a sense of how much caching improves performance," Leong says, adding that businesses can then decide if basic caching is enough or they need a more sophisticated service.
Test results can moreover back enterprises bag buy-in from multiple stakeholders within their companies since CDNs don't drop strictly under the jurisdiction or budget of networking or IT.
Testing made the inequity for About.com, one of the oldest established web properties. The novel York-based company, launched in 1997, offers more than 3.5 million pieces of largely static content on about 1,000 topics that generate about 30 million page views a month. For years, the company assumed most of those page views came from North America, says Matt Landolf, About's director of operations.
About.com has traditionally tested content delivery every yoke of years, and the results were never compelling enough to warrant buying CDN services, so it continued to serve its content from its three POPs in San Jose, Dallas and novel York. That changed in 2012 when the team extended testing to international locations with both Akamai and Fastly.
"We maintain really qualified BGP (Border Gateway Protocol) peering and are partnered well, and they were silent under the impression that most of their main audience was in North America," Landolf says. Expanding its testing to Australia and Southeast Asia showed those segments of About's audience had grown and that it could win an unacceptable eight seconds to bag a page served in some locations.
"We chopped down their response time by more than half for 20% of their audience with just a quick change," Landolf says.
About.com chose Fastly's CDN services, and uses other services from Akamai. The biggest selling point to the About.com developers and decision-makers concerned about making a titanic change was seeing how quickly they could design changes to Fastly's global caches.
Using Fastly's Instant Purge feature, "If there was a mistake or something unforeseen happened, you could change it and the configuration would breathe replicated around the world in less than three seconds," Landolf says.Who will buy?
Pain points usually drive the search for a CDN service, but CDN buyers aren't easily classified. Not only Do the types of businesses buying CDNs vary, but the stakeholders within them maintain a wide orbit of roles that embrace network architects, network security architects, web application developers, CIOs, chief marketing officers, even individual lines of trade that may maintain a mobile app they want to fulfill better.
Coming from a nontechnical background, Mirjana Novkovic, vice president of marketing at speakers bureau Harry Walker Agency, needed to ameliorate video delivery via the agency's website. The company represents hundreds of experts in a variety of fields -- including Bill Clinton, Henry Kissinger, Michael Eisner and Tim Berners Lee, to mention a few -- and books speaking engagements for them around the world.
As head of marketing, Novkovic wanted to design the 1,000 videos on Harry Walker's website load faster and play consistently for booking agents and visitors to the site who were looking for an event speaker. Her path to CDN awareness came after she watched a webcast on video platforms while on maternity leave and received a white paper from Limelight Networks about CDNs.
After reading it, Novkovic decided to embrace CDNs in her video platform search process.
"It was really a huge learning curve for me because I'm not a technical person, so they were looking for a ally that could truly breathe an extension of their department," she says.
In her conversations with top video platform providers and CDNs, Limelight won hands-down for customer service and the information they provided her company. If she has a problem, Novkovic says she sends a quick email and gets one prerogative back from someone on the case. "It's a name, a person I can call. I arbitrator that's so important. They provided more than 200% over what I was even looking for," she says.
In the growing CDN service market, most providers present businesses content delivery services along with crossover services that embrace security, video and optimization. And by targeting specific businesses and making their networks more programmable, Gartner's Leong says more CDNs are addressing segments of the market that haven't been included in the past. At this point, almost any company could potentially need a CDN.
The novel WCAU-WWSI facility, set for a grandiose 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 moving in a slight cinch 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 general manager of NBC10 and sister station WWSI (Telemundo62). “It’s going to give us the best skyline shot of Philadelphia.”
The facility, moreover home to WWSI, offers distinguished views from any of its windows. It’s located on three floors (12-14) of the 60-floor, 1,121-foot Comcast Technology focus in downtown Philadelphia.
Inward from Studio A, you can gawk across a glass enclosed, two-story atrium to contemplate 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 travail together.
But the actual marvel of the zone 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 faculty to keep video coming in and maintain it proceed anywhere else in the plant,” says Tony Plosz, WCAU-WWSI VP of engineering and operations.
“I moreover wanted the flexibility so that staff could expend any system, and travail anywhere across the floors, or even in the field. The ‘anywhere, anything’ philosophy was really titanic in the design.”
Having originally planned to launch in late 2017, NBCU has been letting its 2018 launch date — now set for sometime this drop — quietly slip as engineers travail to finalize software and staff gets up to hasten on updated platforms.
“We are using the latest versions of the technologies they maintain installed, and they are working now to design 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 maintain 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 fancy 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 spin into functioning office space.”
Integration And Connectivity
Comcast Technology focus is hasten by NBC parent Comcast and actual estate investment confidence 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 general contractor of the pile 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 travel 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 selfsame platform,” says Plosz. “They maintain identical control rooms, the selfsame technology in the studios, everything is the same. Before, so much was keep 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 point to collect at a pod — one of several long narrow black tables topped by black monitors — where they can collaborate as they bag 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, point to 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 minute 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 maintain 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 large green screen that covers the entire rear wall, giving the station the opening to Do complete virtual set operation in the future.
Plosz sees that third studio as a “really supple space” that will breathe used for special advice segments as well as being employed by creative services to capitulate 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 large conference leeway and the Central paraphernalia leeway (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 win 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 proceed with an IP routing core. But at that point the SMPTE 2110 touchstone didn’t yet exist, and vendors at the 2016 NAB point to 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 minute 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 win 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 aboriginal 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 hasten cable to one back row, as the all router is distributed across mulitple rack rows.
When Plosz began looking in 2016 at broadcast vendors to advocate 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 large IP installations at major broadcasters fancy ESPN, using its proprietary ASPEN video-over-IP transport protocol.
“They did so well before there were any standards created — they were moving IP packets and they had some age product,” says Plosz. “But what was the inequity between that and a traditional SDI router? They were moving IP video around, but it was silent done through their own switch, and you couldn’t travel 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 silent needed the complete advocate of whatever traditional broadcast vendor was interfacing with it.
“Grass Valley is their ‘one throat to choke,’ so to speak,” jokes Plosz. “We maintain a distinguished relationship with Cisco, but if they maintain any issues, they proceed to Grass Valley.”
In addition to the IP gateways, Grass Valley has moreover supplied its LDX 86 studio cameras. Besides Cisco and Grass Valley, other key vendors for the novel facility embrace 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 fragment of the Comcast enterprise means this novel facility has an incredible amount of fiber-optic connectivity. That is necessary when housing a station in a skyscraper, notes Plosz, as he’s not going to zone a microwave tower on the roof.
“This pile 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 focus with 1,100 access points. complete the major wireless carriers maintain multiple transmitters in the building, says Plosz, and cellphones travail 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 hasten on the Comcast IP network. The facility is moreover 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 silent some microwave gear there, and a minute satellite farm,” says Plosz. “We’re going to extend their Media Fabric over fiber out to Roxborough and design it fragment of their [network], an operator here could haul from there and won’t know any difference. They wouldn’t breathe able to Do 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 trait and reduce noise, and incorporates other green features fancy capturing natural light from its wall-to-floor windows, water and energy conservation throughout and automated window shades to reduce summer heat. The stations maintain moreover tried to expend Energy Star-compliant displays and computers wherever possible.
The stations maintain applied for an LEED Platinum certification, which if approved by the U.S. Green pile Council, would breathe the first time a local broadcast TV station achieves the Platinum LEED level.
Another unique feature of the Comcast Technology focus 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 deal their newsroom as a fourth studio,” says Plosz. “Now the pile becomes that fifth studio — there are so many places to easily plug in and proceed live.”
