  1. Ameritech NAP Update NANOG Feb. 2, 1999 Andrew Schmidt andrew_schmidt@ameritech.net

  2. Chicago NAP’s Applications BBN, AboveNet, Sprint, AT&T, AGIS, C&W,... Internet Service Providers ~60 Michigan, Wisconsin, Illinois, Indiana, Ohio, Iowa, ND, Minn.,... ~14 Universities Norway, Japan, Singapore, Taiwan, Canada, Israel, France, Holland,... ~6 International ~4 U.S. Government Government: NASA, Energy, Defense

  3. 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

  4. 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

  5. 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)

  6. 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

  7. 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

  8. 500 500 New NAP Topology CBX-500 CBX-500 DS-1 DS-3 OC-12c trunk GX-550 DS-3 6 Mb IMA dual OC-12c trunks dual OC-12c trunks OC-12C OC-3c OC-3c

  9. 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
