What is the Chicago NAP • ATM based exchange point • Connection speeds of DS3, OC3c, and OC12c • Each customer gets a full mesh of PVCs • No ingress policing, i.e., UBR service • Little to no traffic loss due to congestion
General Status • Currently, there are approximately 85 connections with several additional pending • Big News: OC12c for both ISPs and R&E. First one implemented for ConXioN in December ‘98. • Five additional pending • Chicago NAP load is approaching MAE-EAST’s • OC-12’s should push load above MAEs in 1999 • Platform changes and renumbering also underway • Consensus from BOF is to utilize MERIT
STARTAP Status Connected / Pending Sites TANet (Taiwan) RENATER (France) SingREN (Singapore) CANARIE (Canada) MIRnet (Russia) TRANSPAC (Asian) NORDUnet (Norway) NACSIS (Japan) SURFnet (Netherlands) Q-MED (Israel) CERN (Switzerland)
Switch Migration:Existing switch platform • Lucent Technologies • Globeview (GCNS) 2000, Release 1.3 • Single switch design • 20 Gbits/sec shared memory fabric • Non-blocking path from fabric to each port • DS-3 and OC-3c interfaces available • Limitations • No OC12c, SVC’s, and EPD available in current release • New release is OK but requires forklift hardware upgrade
New switch platform • Ascend Communications CBX-500/GX-550 • Tiered structure • CBX-500 will service DS-3, DS-1 and DS-1 IMA • GX-550 will service OC-3c, OC-12c, and OC-48c • SVC support • UNI 3.0, 3.1, 4.0, IISP 3.0, 3.1, PNNI 1.0 • Integrated with AADS’ frame-relay network and management system

NAP Directions? • Traffic engineering capabilities • Various ATM traffic classes VBR, CBR,… • Inter-provider traffic management • Enhanced online reporting • WWW based reports • inter-provider capacity/utilization reports
