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

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

6. 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)

7. 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

8. 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

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

10. 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
