NEC plots a 100 Gbps course
While the idea of bringing even multiple Kbps or even a megabit was once thought of as science fiction, today enterprises and consumers are getting multiple Mbps and even Gbps of bandwidth. Such traffic is driving service providers to consider migrating to 40 and even 100 Gbps backbones. In the following Audiocast, Sean Buckley, Editor in Chief of Telecommunications, talks to Rocky Kler, vice president and general manager, NEC Corporation of America, Optical Network Systems Division, about the potential of 100 Gbps networking.
Kler answers the following questions in this Audiocast:
At the recent FTTH Council Europe conference in Paris, France, one of the opening keynotes called Estimating the Exaflood: The Impact of video and rich media on the Internet by Bret Swanson of the Progress and Freedom Foundation talked about new video applications and one of the drivers to increase Internet traffic. Do you believe that Web-based consumer and business applications, not to mention increasing FTTH deployments, are driving service providers to upgrade their networks to support 40 and potentially 100 Gbps networking?
The notion of 40 and now 100 Gbps transmission has been talked about for a number of years. What is making 100 Gbps more of a reality today?
Late last year, Verizon Business conducted a 100 Gbps field trial carrying a FiOS TV feed in its Florida market, while Level 3 built a non-native 100 Gbps network for Internet2. Are these trials lending credence to the idea that 100 Gbps networks can work in an actual live network?
Let’s switch to NEC. Can you talk about some of the innovations you’re working on within NEC to drive the migration to 100 Gbps?
What are the components of NEC’s strategy?
Exalt takes the hybrid wireless backhaul route
When the wireless network was all about voice, simple E1/T1 circuits were sufficient, but the rise in all-you-can-eat voice minute plans and new data-driven devices like the iPhone are all putting new demands on a network that was basically designed for one thing: to talk.
As a result, wireless operators are having to rethink how they deploy their wireless backhaul network infrastructure. Amir Zoufonoun, Chief Executive Officer and founder of Exalt Communications talks about how operators can address working with today’s TDM reality despite the wireless IP future.
In this Audiocast, Zoufonoun addresses the following questions:
• When it comes to wireless backhaul, the two dominant forms have been either E1/T1 and TDM-based microwave solutions. Now, a recent report from Infonetics says that Ethernet/IP-based microwave backhaul is forecasted to be a US$1.8 billion market by 2010. What is driving this trend?
• While we all want to be all-IP, all of the time even with wireless, in the real world, there’s going to be (for quite a long time) a mix of TDM and IP. To address that need, Exalt has a vision of carrying IP and TDM in its native form. Talk about your approach and why you chose to go that route?
• What are the measurable benefits to the deployment of Ethernet solutions for backhaul applications?
• One issue that’s gaining momentum is dealing with clock synchronization when using Ethernet for wireless backhaul. How is Exalt addressing that issue?
Alcatel-Lucent brings IPTV to the next level
Already working with some of the largest service providers, including Telekom Austria, Alcatel-Lucent continues to make a name for itself in the burgeoning IPTV market. In this Audiocast, Sean Buckley talks with Jim Guillet, Assistant Vice President of Triple Play product marketing for Alcatel/Lucent, about how service providers can leverage their broadband network and IPTV network build outs to generate a sound return on this new investment.
In this Audiocast, Guillet addresses the following questions:
• IPTV, and really the whole idea of telco TV, has gone through various iterations, but from where you sit what’s your sense of the state of the market overall?
• To help service providers ramp up their IP video offerings, Alcatel/Lucent recently made a number of new enhancements to its Triple Play Service Delivery Architecture (TPSDA), already deployed by large operators such as Telekom Austria AG. What drove Alcatel/Lucent to make these new enhancements?
• One of the elements of TPSDA is its ability to deliver and enforce policy end to end. How has the role and advancement of policy management changed over the years and how will be it be applied in the telco video market?
• In addition to Policy Management, Deep Packet Inspection (DPI) continues to come up more and more recently with various DPI-centric vendors beefing up their wares. What’s ALU’s approach to DPI?
• Another concept to emerge in the telecom video age as providers ramp up their service rollouts is the notion of Quality of Experience (QoE). What’s your definition of QoE, and what steps can service providers take to be proactive about ensuring QoE in the home?
• While there’s a lot of talk about IPTV, Over the Top (OTT) video or online video continues to ramp up. How does that play into the overall telco video market?
Fujitsu takes the pain out of wireless backhaul
Offers simultaneous support for TDM and IP/Ethernet
When the wireless network’s main application was voice, a traditional T1 circuit in the backhaul network was sufficient.
However, the bursty nature of data-centric applications that will run over the CDMA and future LTE paths will require a flexible such as IP/Ethernet. Executive Editor Sean Buckley speaks to Jim Orr, principal network architect in the wireless market development group at Fujitsu.
In this Audiocast, Jim Orr answers the following questions:
• When it comes to wireless backhaul, the two dominant forms have been either E1/T1 and TDM-based microwave solutions, but now we’re hearing more about carriers adopting or considering using IP/Ethernet for wireless backhaul. What’s driving the migration from TDM to IP/Ethernet for wireless backhaul and what measurable benefits to the deployment of Ethernet-based solutions for backhaul applications?
• To help ease the migration pain for a wireless operator using Ethernet for backhaul, there’s been talk about maintaining TDM for voice and then Ethernet for data. Are you seeing a similar trend?
• One issue that’s gaining momentum is dealing with clock synchronization when using Ethernet for wireless backhaul. How is Fujitsu addressing that issue?
• As service providers — such as Verizon and AT&T with their FiOS and U- Verse last-mile strategies — pull fiber closer to residents, it’s likely that that same fiber could potentially be pulled into cell sites, which often run along similar paths. Do you believe that service providers will also leverage their fiber investments to the home and bring them to cell sites?
• Ultimately, fiber will be the dominant form for backhaul, but during last year’s CTIA show, one trend to come out of discussions was centered around Ethernet over Copper solutions for wireless backhaul. Are you seeing growing demand for such platforms?
