3 Abilene – July, 2001 Inflection point in network development OC-48c (2.5 Gbps) IP-over-SONET backbone 50 current and pending connections in 33 states –Three OC-48c connections: P/NW, SoX, and MAX –16 connections at OC-12c or higher (~50% by 12/01)  Strongly encouraging SONET at OC-12c 190+ participants in 50 states and D.C. –Puerto Rico soon Ongoing strong partnership Corporate: Cisco, Nortel, Qwest NOC: Indiana University ITECs: North Carolina and Ohio

7 Network of the Future: Context for the next backbone Computational science as an emerging interdisciplinary field Bandwidth as the fourth critical parameter –CPU, memory, storage Increasingly distributed data collection and storage NSF Distributed Terascale Facility solicitation Emergence of optical transport technologies Dense Wave Division Multiplexing (DWDM) Important distinction: transport vs. switching Much new transcontinental conduits and fiber in place; a lot of business plans abandoned… Important correction to NYT and WSJ articles (6/18/01): –Fiber/conduit – not bandwidth – glut

8 DWDM system components Multiplexing terminals ’s per fiber pair Amplifiers All optical (OO) Needed every ~100 km Regenerators OEO – electronic signal processing Long haul (LH): needed every ~500 km Ultra long haul (ULH): needed only every ~2500+ km Organizational scale correspondence (LH) Metro (campus): no amplifiers Regional (GigaPoP): no regenerators National (backbone): regenerators or ULH needed Ren

9 Network of the Future/Backbone Strategic goals Incorporate optical techologies into the core of the network Continue to work with regional GigaPoPs in a hierarchy High performance interconnection with international nets Emphasize advanced services –high-performance IPv6 –line-rate multicast (ASM, SSM) –enhanced, native measurement capabilities –make differentiated-services based QoS work –play our role in End-to-End Performance Initiative
