  14. Advanced services on Abilene • Multicast • IPv6 • Measurement • Quality of service (QoS) • IETF Differentiated Services model

  15. Advanced services - Multicast • Abilene is a leading backbone globally in aggressive protocol deployment (MBGP, MSDP, PIM-Sparse, SSM) • Early detection of the Ramen worm • Deployment • 72% of BGP peerings are multicast-enabled • Peering at MIX (NASA Ames) and soon elsewhere • However, multicast remains an experimental service

  16. Advanced services – IPv6 • Overlay network of Cisco 7206 routers • Collaboration between Abilene NOC and I2 v6 WG • Initial ARIN address allocation received • Planning for v6-only peering with WIDE (Sunnyvale) • Is v6’s time coming in the U.S.? • wireless, • End-to-End Architecture • International deployment efforts • Watch this space…

  17. Advanced services - Measurement • Open network measurement stance • Active measurement: Surveyor • Traffic characterization project: Ohio ITEC • Source/destination matrix, traffic types • Requested measurement services • Passive measurement (MOAT) • Off-net Netflow feeds • Will play a strategic role in End-to-End Performance Initiative • NOC and Measurement WG • DDoS detection testbed (Asta Networks)

  18. End-to-End (e2e) PerformanceInitiative • Human to Human Collaboration Experience • User perception EYEBALL • Application CORE APPLICATION • Operating system • Host IP stack STACK • Host network card • Local Area Network (LAN) JACK • Campus backbone network • Campus connection to regional network/GigaPoP • GigaPoP connection to Internet2 national backbone • International connections
