STAR TAP ITNRouter and Routing Policy

• STAR TAP ITN is AUP Free– Accepts routes & traffic from any participating National

Research Network (NRN)

(does not include commercial/commodity traffic & routes)

– Configured to avoid accidental use of ST ITN for intra-continental/intra-regional routing (e.g. Singaren <–> APAN via ST ITN)

– Networks may opt out of exchanging routes with subset of participants (has not been requested to date but is an option)

Proposed Abilene Regional Aggregation Areas

SUMMARY• Problem:

– optimizing International Connectivity to North American National Research Networks

– not all peering points offer Layer 2 bilateral peering solutions from a single vendor

– ensuring International Networks get full connectivity

• Solution: – extend the STAR TAP International Transit Network

to other geographic locations
