Agenda
• RedCLARA Connections
• Global Routing Policy
• Network Services
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

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

Services of the network
• Multicast
• IPv6
• IPv6 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

1 – create the tunnel
2 – apply PBR
3 – marking and forwarding
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
