  20. Agenda • RedCLARA Connections • Global Routing Policy • Network Services

  21. RedCLARA Routing • RedCLARA is peering with several Regional Networks through its access links from ALICE and WHREN-LILA projects • Some of these peerings have multi-homed configuration (possibility to access the network through different connections) • The global policy adopted by RedCLARA is geographic proximity – NRENs will preferentially use the nearest exit to exchange traffic with other networks

  22. RedCLARA Routing Pacific Wave 1.0 Gbps GEANT 622 Mbps WHREN-LILA TEP 2.5 Gbps

  23. RedCLARA Communities • All internal and received prefixes will be marked to one or more BGP communities • There are 3 basic types of peerings: ITN (International Transit Network), Connector (regional network) and NREN • NREN receives all prefixes • ITNs and Connectors receive only NREN prefixes, unless there is a specific agreement for transit

  24. RedCLARA Communities Pacific Wave 1.0 Gbps GEANT 622 Mbps WHREN-LILA TEP 2.5 Gbps NREN set community 27750:64100 ITN set community 27750:64200 CONNECTOR set community 27750:64300

  25. Agenda • RedCLARA Connections • Global Routing Policy • Network Services

  26. Services of the network • Multicast • IPv6 • IPv6 Multicast • Bandwidth Availability

  27. Traffic Engineering • Use of MPLS Traffic Engineering in the backbone • Applications sensitive to delay could “indicate” to the network their requirement for a different path • Manually defined tunnels should prevail over the normal IGP routing decision process

  28. Traffic Engineering • Round-Trip Times of the links Tijuana RTT 70 ms RTT 160 ms RTT ?? ms Panama Sao Paulo RTT 55 ms RTT 25 ms RTT 20 ms Santiago Buenos Aires

  29. Traffic Engineering • Use of MPLS-TE Tijuana Panama Sao Paulo traffic Santiago Buenos Aires

  30. Traffic Engineering • Use of MPLS-TE Tijuana MPLS-TE tunnels Panama Sao Paulo Santiago Buenos Aires

  31. Traffic Engineering • Steps 1 – create the tunnel 2 – apply PBR 3 – marking and forwarding Tijuana Panama Sao Paulo Santiago Buenos Aires

  32. Traffic Engineering and QoS • It is possible also to give preference to the marked traffic • RedCLARA is investigating the proper tools to classify the traffic entering the network • MPLS-TE has embedded tools for delivering QoS to the applications
