1 March 2016 Extreme Networking – Experimental Ultra-High Speed Networks Rick Summerhill - Moderator Director, Network Research, Architecture, and Technologies, Internet2 Fall Member Meeting Austin, TX

Ultra-High Speed Networking  In previous upgrades of R&E networks, the pipes were simply made larger Occurred during the NSF backbone days First upgrade of Abilene went from 2.5 Gbps to 10 Gbps –Same basic design of the network, however. The architecture remained basically the same  Is that the path to the next generation network? Perhaps parallelization is the next step? Or a completely new architecture utilizing ideas from the circuit switched world?

Ultra-High Speed Networking  40 Gbps is available on some platforms today At least one OC-768 router blade is available Waves can be supported by remodulating 10G waves  Technically not difficult to deploy, but the economic incentive has not been there to this point Commodity providers can parallelize easily – they deal mostly with small flows Commodity providers have almost no applications that require this type of bandwidth There are applications in the R&E world that could use these high bandwidths  What does the future hold for capacity? 100 Gbps? 1000 Gbps? Etc?

Ultra-High Speed Networking  We’ve asked two industry leaders deploying 40 Gbps to comment on further evolution of ultra-high speed networking in the wide area  Both currently have 40 Gbps under development
