Agenda • Red. CLARA Connections • Global Routing Policy • Network Services
Red. CLARA Routing • Red. CLARA 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 Red. CLARA is geographic proximity – NRENs will preferentially use the nearest exit to exchange traffic with other networks
Red. CLARA Routing Pacific Wave 1. 0 Gbps GEANT 622 Mbps WHRENLILA TEP 2. 5 Gbps
Red. CLARA 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

Agenda • Red. CLARA Connections • Global Routing Policy • Network Services
Services of the network • • Multicast IPv 6 Multicast Bandwidth Availability
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
Traffic Engineering • Round-Trip Times of the links Tijuana RTT 70 ms Panama RTT 160 ms RTT ? ? ms RTT 55 ms Santiago Sao Paulo RTT 25 ms RTT 20 ms Buenos Aires
Traffic Engineering • Use of MPLS-TE Tijuana traffic Panama Santiago Sao Paulo Buenos Aires
Traffic Engineering • Use of MPLS-TE Tijuana Panama Santiago MPLS-TE tunnels Sao Paulo Buenos Aires
Traffic Engineering • Steps 1 – create the tunnel 2 – apply PBR Tijuana Panama Santiago 3 – marking and forwarding Sao Paulo Buenos Aires
Traffic Engineering and Qo. S • It is possible also to give preference to the marked traffic • Red. CLARA is investigating the proper tools to classify the traffic entering the network • MPLS-TE has embedded tools for delivering Qo. S to the applications
