Objectives of the projects
Develop an advanced testbed for experiments and validation of an Advanced Terabit Router (ATR) : the A7770 RCPWP1 : Installation and integration of the NetworkWP2 : Conformance , Interoperability and Performance testing
Research, Design and experiment with a set of traffic management algorithms and protocolsWP3 : Intra-domain traffic engineering, use of QOS in LSP,
multicasting, use of MPLS resilienceWP4 : Inter domain traffic engineering, impact on BGP and RSVP-TE
Test the final version of the ATR with very high demanding applicationsWp5 : Demonstration and Experiments

In non-DiffServ networks:Non-DiffServ BE
Two queues are used: IP/MPLS and IP control trafficNon-DiffServ BBE
Three queues are used: IP, MPLS and IP control traffic
In DiffServ enabled networks:DiffServ IP
Twelve queues are defined: AF1-4, BE, EF, control trafficDiffServ IP/MPLS
Same as DiffServ IP, but for MPLS the EXP bits are interpreted
Sceduler is based onWeighted Fair QueuingStrict Priority Queuing ( for EF traffic ) -> available in April 02

Extra focus on
Workshop for TF-NGN and IST members in April
Extension to Poland, Barcelona and Italy ( Moicane ) under
discussion, interconnected via VTHD, Atrium or via GEANT
Tests with 10 Gb on interconnections in June
QOS : ATM-IP mediation using MPLS-TE
Interconnect A7670 to A7770
OPTIP : Include OPTIP program into Atrium
Experiments
Technology
IPv6 : Upgrade A7770 by end 2002 and demonstrate IPv6.
