21 Agenda RedCLARA Connections Global Routing Policy Network Services

22 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

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

24 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

27 Services of the network Multicast IPv6 IPv6 Multicast Bandwidth Availability

28 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

29 Traffic Engineering Round-Trip Times of the links Tijuana Sao Paulo Buenos AiresSantiago Panama RTT 70 ms RTT 160 ms RTT 55 ms RTT 25 ms RTT 20 ms RTT ?? ms

30 Traffic Engineering Use of MPLS-TE Tijuana Sao Paulo Buenos AiresSantiago Panama traffic

31 Traffic Engineering Use of MPLS-TE Tijuana Sao Paulo Buenos AiresSantiago Panama MPLS-TE tunnels

32 Traffic Engineering Steps Tijuana Sao Paulo Buenos AiresSantiago Panama 1 – create the tunnel 2 – apply PBR 3 – marking and forwarding

33 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
