  1. ATRIUM SEQUIN workshop

  2. Objectives of the projects • Develop an advanced testbed for experiments and validation of an Advanced Terabit Router (ATR) : the A7770 RCP • WP1 : Installation and integration of the Network • WP2 : Conformance , Interoperability and Performance testing • Research, Design and experiment with a set of traffic management algorithms and protocols • WP3 : Intra-domain traffic engineering, use of QOS in LSP, multicasting, use of MPLS resilience • WP4 : Inter domain traffic engineering, impact on BGP and RSVP-TE • Test the final version of the ATR with very high demanding applications • Wp5 : Demonstration and Experiments

  3. Partners and contributions

  6. A7770 : Design and architecture Alcatel 7770 RCP: Designed to Excel in New Generation IP Networks High Performance and Scalability Easy and Effective Management Non-StopNetworking Optical IP Internetworking Guaranteed Service Level Agreements

  7. Guaranteed Service Level Agreements Working modes of the Alcatel 7770 RCP • In non-DiffServ networks: • Non-DiffServ BE • Two queues are used: IP/MPLS and IP control traffic • Non-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 traffic • DiffServ IP/MPLS • Same as DiffServ IP, but for MPLS the EXP bits are interpreted • Sceduler is based on • Weighted Fair Queuing • Strict Priority Queuing ( for EF traffic ) -> available in April 02

  8. Guaranteed Service Level Agreements Powerful DiffServ Implementation • E-LSP (EXP-bit inferred LSP) • multi QoS LSP with or without bandwidth reservation • carries up to eight Behavior Aggregates • EXP field encodes DSCP • Pro: less LSPs • Con: more complex network design • L-LSP (Label inferred LSP) • single QoS LSP with or without bandwidth reservation • EXP field encodes Drop Precedence • Pro: simpler network design • Con: more LSPs EF AF1 E-LSP A AF2 BE AS EF L-LSP B L-LSP C AF1

  9. WP2 : Conformance , Interoperability and Performance testing • E-LSP, DiffServ QOS tests ongoing

  10. WP2 : Traffic Engineering Platform tests • Off line Traffic Engineering • Discovery of network • Visualization of • network • Routers and interfaces • capacity • LSPs • primary • backup LSPs

  11. VTHD IP TV Server WP5:Experiments 7770 RCP Liege OC-48 OC-48 n x GE SmartBits GE Congestion ! n x GE QA-Robot FE SmartBits OC-48 FE OC-3 OC-12 7770 RCP Antwerpen 7770 RCP Paris FE FE Netmeeting IP mux OC-12 FE FE AVA Traffic Engineering IP mux 2Mbps Netmeeting & Video client = Connection to the 7770 RCP outband management port

  12. 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.

  13. Core Node 1: Network Dynamic through Management Alcatel 5620 Data Network Management Traffic Management AVA-TE Alcatel 1355 BOND Alcatel 1354, 1353 Transport Management AVA Traffic Engineering • Cross-Domain TE (MPLS and Transport) 1355BOND Bandwidth-on-demand application O-SLA for O-VPN support GMPLS@ OIF UNI protocol Other client’s applications GMPLS@OIF UNI 7770 7670 Any Alcatel Transport network SONET/SDH 7770 RCP

  14. QoS for Mediated Traffic ATM VC/VP ATM VC/VP ATM Traffic Generator ATM Traffic Generator 7670 RSP 7670 RSP IP Traffic Generator IP Traffic Generator 7770 RCP 7770 RCP • Mediation of ATM traffic over a pure IP/MPLS core. • Overload IP/MPLS Core with BE IP traffic. • Show that mediated ATM traffic is not impacted.

  15. Co-operation with SEQUIN • Set the test bed available to the Sequin group • All DSCPs and associated queues are available • Testbed can be loaded, links can be disabled/interrupted • Configure the routers to allow • Premium service • BE Set the testbed under load conditions • Scavenger service ? • AF classes ? • measure • Delay • Loss • Delay Variation • Via a local workshop or via the interconnection with GEANT
