Non STAR TAP U.S./International Peering

• Abilene/SURFnet& NORDUnet– Ref: Guy Almes’ Slides

• CA*net2/3 and US Nets at Seattle

• US - Mexico UCAID/CENIC/CUDI– T1 between SDSU (San Diego) and CICESE (Ensenada)

• Non Backbone Inter Gigapop Links• both not for profit and commercial examples: NYSERNET,

Teleglobe

• STAR TAP is at the MREN Gigapop

STAR TAP

• STAR TAP has:

– Many U.S. and International Peers

– Persistence

– Dedicated AADS Infrastructure/ISP Access

– Value Added Services

– Enough Critical Mass to attract the contributions of many members of our community

– Cutting Edge projects e.g. Optical IX

STAR TAP- IPv4 Router - Benefits

• One stop shopping for most STAR TAP routes• 16 Networks and 15 MREN Universities now at STAR TAP

• More expected next year

• Full peering would require 31*30/2 = 465 sessions

• Complements layer 2 peering not meant to replace it!

• STAR TAP Router is AUP free • Tools will be made available to implement network and link AUPs

• Supports High Performance Multicast

• BFR coming end of 99

STAR TAP- IPv4 Router - Downside

• Extra Hop

• STAR TAP router is meant to complement layer 2 peering not replace it

• If an extra hop is a problem - direct peering is a quick fix

• STAR TAP router can can provide a backup route in case direct route goes down – not likely but a backup route never hurts

University of Illinois at Chicago

STAR TAP- IPv4 Router - Added Value

• Web Displays of Routing Tables

• Indiana University Weather MAP

• Measurement Statistics and Analysis from OC-3MON and Router SNMP MIB

• SNMP Proxy Server

• Internet2 Routing Registry

• Web Caches

• AMP
