Higher-Speed Ethernet Required to Support IP Network Growth: A first-ever demonstration of 100 Gigabit Ethernet (100GbE) technology by a team of industry leaders, including Finisar, Infinera, Internet2, Level 3 Communications, and University of California at Santa Cruz, shows that 100GbE technology is viable and capable of implementation in existing optical networks with 10 Gigabit/second (Gb/s) wavelengths. This breakthrough trial also highlights how next-generation technology can address the emerging bandwidth needs of network providers and their users as advanced Internet-based applications continue to proliferate. The system successfully transmitted a 100GbE signal from Tampa, Florida to Houston, Texas, and back again, over ten 10 Gb/s channels through the Level 3 network. This is the first time a 100GbE signal has been successfully transmitted through a live production network. The 100GbE system will be on display from November 14th to the 16th at the Infinera booth (Booth no. 1157) at the SC06 International Conference in Tampa. The system will be transmitting a 100GbE signal to the Internet2 booth (Booth no. 1451) during the show. "This successful demonstration shows that this concept of 100GbE over 10x10 Gb/s DWDM works and provides a near future implementation path," said Dr. Daryl Inniss, vice president of Ovum-RHK's Communication Components research. "100 Gigabit Ethernet will be a critical technology to accommodate bandwidth growth, and this demonstration shows that we have the capability to implement this as a super-lambda service over today's networks," said Infinera co-founder and CTO Drew Perkins. "The Infinera DTN, which is the only DWDM system that supports 100 Gb/s on a line card, is capable today of handling 100GbE services simply and cost-effectively." "The research and education community continues to be the key driver for the development of extreme bandwidth services like 100GbE," said Steve Cotter, Internet2's director of network services. "We are very interested in investigating this breakthrough technology, in collaboration with our network partners, to ensure that our network not only keeps pace but also anticipates the future demands of our members as they pursue increasingly bandwidth-intensive applications, from telemedicine to high-energy physics to high-performance grid computing, among many others." "This new approach to providing 100 Gig Ethernet service over long distances enables LAN Ethernet protocols in the WAN environment," said Jack Waters, CTO of Level 3. "Compared to other methods that have been demonstrated, this is a practical, economical solution that operates over the wide area using existing DWDM technologies. We're pleased to have been involved with developing and testing this solution, and will be watching closely as it is commercialized." Super-Lambda Services The largest IP backbones are currently using multiple 10 Gb/s links between core sites, and will soon demand 100 Gb/s connections to increase their capacity to keep up with fast-growing bandwidth demand. Many service providers prefer to support 100 Gigabit Ethernet links using their current transport network infrastructures. This demonstration shows that today's 10 Gb/s transport networks can support 100GbE services. The system developed and displayed this week relies on a single-chip 100GbE network interface that implements a lane alignment and packet resequencing scheme to bond 10 parallel 10 Gb/s channels into one logical flow while maintaining packet ordering at the receiver. This eliminates the performance issues that can arise with the use of the existing link aggregation techniques for combining multiple data channels. Services that combine multiple wavelengths to offer a single service are referred to as super-lambda services. Finisar provided the optical transceivers for this demonstration, Infinera provided the DWDM system and project management, Internet2 was involved in developing the methodology and supporting the demonstration, Level 3 Communications provided the ten 10 Gb/s channels from Tampa to Houston, and UCSC designed and implemented the network interface including the packet resequencing scheme. Video: A High-Speed Application The research and education community is a leader in creating very large flows on the Internet, with some research institutions planning on flows in multiple hundreds of Gigabits/second or even Terabits/second. In a related demonstration at the Internet2 booth on the SC06 showfloor, Internet2 and Infinera will also showcase an advanced two-way videoconferencing application. Reliable, two-way video technology is quickly becoming a critical and necessary component of many important research and education initiatives including those in telemedicine, seismology and astronomy. 100GbE technology would enable more than 3000 DVTS (Digital Video Transport System) or more than 60 uncompressed High-definition TV (HDTV) video applications to operate simultaneously on a single interface. Industry Standard is a Priority The IEEE Higher Speed Study Group (HSSG) recently began working on specifications for higher speed Ethernet. The partners in this demonstration are actively supporting these efforts. The pre-standard specification used in this demonstration was jointly developed by Infinera and a UCSC team including Professor of Computer Engineering Anujan Varma and his Ph.D. student Arvinderpal S. Wander. The annual SC06 International Conference on High-Performance Computing, Networking, Storage, and Analysis will be held at the Tampa Convention Center in Tampa, Florida.
