12. University of Illinois at Chicago 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

13. University of Illinois at Chicago 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
