TransitRail: National Commercial Peering Exchange Program
TransitRail: National Commodity Peering Program May 16, 2006 Quilt Minneapolis Copyright 2006 CENIC and PN WGP Premise Successful large-scale commodity Peering can... Decrease commodity costs and result in overall savings Reduce reliance on commercial vendors
Increase routing efficiency and flexibility Copyright 2006 CENIC and PNWGP TransitRail Is/Will Be... NATIONAL Multiple exchange locations around the US; COMMODITY packet-agnostic Connections at commercial peering exchange points; PEERING Direct network-to-network bilateral IP Packet exchange Copyright 2006 CENIC and PNWGP
TransitRail Goal Goal: create a network presence and infrastructure that will attract and retain TierOne type peering to the benefit of the R&E community Copyright 2006 CENIC and PNWGP What to Expect TransitRail participants are likely to experience anywhere from a 25% to 60+% reduction in the overall traffic that normally
goes over their commodity ISP circuits. Copyright 2006 CENIC and PNWGP CENIC Experience 9000 Commodity only - no R&E 8000 7000 6000 Peering Volume Transit Volume Aggregate

Copyright 2006 CENIC and PNWGP TransitRail is NOT R&E network peering Regional/local peering Many-to-many peering facility An alternative for 100% of all your commodity transit needs Pacific Wave Copyright 2006 CENIC and PNWGP Who CENIC and Pacific Northwest Gigapop are jointly proposing, developing, and implementing the TransitRail facility.
These groups have significant individual and joint experience with peering facilities and prospective peering partners Partnering with NLR who will provide the underlying network infrastructure as well as the relationship with the participants.

Peering node builds: LA, Sunnyvale, Seattle, Chicago, Washington DC. Location selection criteria: a) reasonable proximity, and access, to an NLR POP; b) dispersed east-west locations; c) highest peering potential based on fiscal investment for that location. Initial participants: PSC, FRGP, MATP, CENIC, PNWGP Interest expressed: LEARN, SOX Copyright 2006 CENIC and PNWGP Infrastructure Equipment (CISCO 7600s) Links (NLR Framenet), loops
