  2. Outline • Network Overview • Layer 1/2 Peering - Update • GLIF/GOLE Activities/Infrastructure: • The WHREN-LILA project • AtlanticWave • Open Exchange Points in the Western Hemisphere 2 Quilt Peering Workshop, October 2006

  3. AMPATH International Exchange Point Characteristics • Current Technologies: • Various 10 GigE circuits currently in place to other networks include: • 10 GigE to FLR ( Florida’s RON ) • 10 GigE to UltraLight’s • 10 GigE to AtlanticWave ( Week ending Oct. 13th ) • 10 GigE to SC 06 SCInet - Delivering A-Wave to SC. • NRENs peer directly with AMPATH via international circuits. • NRENs peer with Abilene via multi-hop eBGP; however this will change with A-Wave implementation. • Direct peering to other NRENs available via AtlanticWave, WHREN-LILA circuit, FLR or UltraLight. • Located at Miami’s Tier-1 NAP: NAP of the Americas Quilt Peering Workshop, October 2006

  5. WHREN-LILA IRNC Award 0441095 • 5-year NSF Cooperative Agreement • Florida International University (IRNC awardee) • Corporation for Education Network Initiatives in California (CENIC) • Project support from the Academic Network of Sao Paulo ( ANSP ) • CLARA, Latin America • CUDI, Mexico • RNP, Brazil • REUNA, Chile • Links Interconnecting Latin America (LILA) aims to Improve connectivity in the Americas through the establishment of new inter-regional links • Western-Hemisphere Research and Education Networks (WHREN) serves as a coordinating body whose aim is to leverage participants’ network resources to foster collaborative research and advance education throughout the Western Hemisphere 5

  6. Links Interconnecting Latin America • Miami - Sao Paulo link: 1.2Gbps by year end, evolving to 2.5Gbps • Connects State of Sao Paulo academic network (ANSP) and Exchange Point, regional network (CLARA), Brazilian NREN (RNP), other international networks • San Diego - Tijuana link: operating at 2 x 1 Gbps, providing dedicated GigE links to regional network (CLARA) and Mexican NREN (CUDI) • East and west coast connectivity to I2 Abilene and other US and global R&E networks http://www.whren-lila.net

  7. Current RedCLARA topology • backbone ring: 155 Mbps(Global Crossing + Cisco) • Access links of 10 to 45 Mbps • Connection to Europe (GÉANT) at 622 Mbps from Brazil

  9. Sao Paulo Exchange Point Characteristics • Built using Cisco ONS 15454 SDH Chassis • STM circuit between Miami and Sao Paulo is configured currently as VC4-8c ( ~ 1.22 Gbps ) linear circuit • Drawback: Static Provisioning, tear-down required if peers require additional bandwidth • VCAT and sw-LCAS can be used to accommodate network dynamics ( SC ‘06 ) • STS-v ( VCAT ) circuits along with sw-LCAS allows network reconfiguration without service interruption and provides greater circuit granularity • Ethernet L2 End to End Service currently provided using ML-1000-2 cards installed on ONS • Currently 2 ML cards provide a total of 4 GigE ports ( can add more if needed ) • GigE ports can be configured with various 802.1Q VLANs as well as transport user-defined VLANs using QinQ mapping • Bridge groups provide the necessary mappings via internal ONS cross-connect fabric to previously provisioned SDH circuits • CoS/QoS and other policing methods can be applied to ML ports to conform to requirements as well as QinQ VLAN mappings Quilt Peering Workshop, October 2006

  11. Future Implementation Goals • Flexibility for end user requirements • ONS ML GigE ports assigned to individual end users to accommodate end2end flows ( LHC experiments, network research ) • To accommodate 2 x 1 Gbps flows and an additional 300 Mbps flow: • Circuit provisioned using 2 x STS-12c-2v (1 Gbps) VCAT groups, an additional STS-3c-2v ( 300 Mbps ) VCAT group and/or multiple STS-1c-2v circuits over the STM-16 circuit. • sw-LCAS can be used to accommodate network dynamics. This means bandwidth can be re-provisioned while not affecting data flows. • Achieves: Granularity to 51 Mbps ( I.e: efficient use of bandwidth ) • Traffic Engineering • Peers are can be guaranteed bandwidth at port speeds or given CoS via policing which ensures better than best effort availability for sensitive data flows • VLAN mappings can be preserved throughout; a combination of Ethernet Wire Services or Ethernet Relay Service can be implemented using ML card to ensure flow separation and data security/integrity 11 Quilt Peering Workshop, October 2006
