What’s different now?What’s different now?
•Over the last 5 years, the U.S. research universities have become wholesale customers of telecoms for raw assets & ancillary services•Upwards of 30,000 route-miles of inter-city dark fiber are held by this community• > 60% in the regionals
•More than 20 Regional Optical Networks (RONs) have emerged • mostly state based• many with strong gubernatorial support• often concurrent economic development objectives
• All at a time when carriers have not made major CapEx in new optical infrastructure

What’s different now?What’s different now?
• Increasing end-to-end network transparency• A high-end server is capable of transmitting aggregate flows of O(10) Gbps on the global scale• A well-tuned IP network can sustain this flow
•Grid computing wants to view the network as a schedulable resource•On par with CPU, memory, storage, and visualization capabilities
•Active examination of new network service models is underway•Moving beyond the common bearer service view of best-effort IP

Implications for campus networksImplications for campus networks
• We’ve spent a lot of time the last 4 years on national and regional networks
• But what about the campus?• Just ask Bill Decker and the CETF! (talk #3)• Emerging suite of differentiated services has
significant implications for the campus• Provisioning and support models• Campus colocation (‘co-generation’) facilities
• Fertile ground for hard work• Planning for workshop this fall

ConclusionConclusion
•Thanks to the relentless acquisition and innovative infrastructure development efforts of the last few years, we have the opportunity to build a new form of service-rich network from the ground up•Not just reinventing the telco way• The real work has just begun…•Critical: a commitment to open standards and interoperability as new services develop from the crucible of testbeds and advance capabilities
