Preferred technology to implement large IP-only networks Building Blocks to implement Service Level Agreements for IP Service Providers Easy implementation of IP VPNs Site 1 of business unit 1 Customer Edge (CE) Provider Edge (PE) Service Provider Network Site 2 of business unit 2 Site 2 of business unit 1 Site 1 of business unit 2 Site 3 of business unit 1

8 Current State of Interoperability Area Signalling protocols LDP and RSVP-TE Status Good interoperability achieved for basic protocol functions Traffic Engineering (RSVP-TE / CR-LDP) Not fully tested yet Implementations are still proprietary to some extent MPLS/BGP VPNs Layer 2 VPNs Only basic interoperability achieved; more implementations and protocol features become available Standards still under development

9 Current State Summary Basic Interoperability between different vendors - demonstrated at several events! Basic interoperability tests necessary only to guarantee that existing and new implementations work together How to realize services?! A lot of options in the MPLS standards Not all vendors support all of them! Which options and test scenarios are important for the users of MPLS?

10 Deployment of MPLS Networks Recent service provider deployments include AT&T, Equant / Global One, British Telecom and many other Service Provider Currently deployed MPLS networks are usually! Single-vendor networks! Sometimes dual-vendor (different core / edge products)! Using MPLS VPNs! Rarely implementing real MPLS Quality of Service throughout the core network

11 Hot Topics and future test areas for the development of full interoperable multi vendor networks

12 Hot Topics of MPLS Testing (1) Virtual Private Networks:! Build multi-vendor VPNs on IP layer! Focusing specifically on inter-carrier connections (Autonomous System Border Routers)! Establish interoperable Ethernet, FrameRelay, ATM tunnels (layer 2 VPNs)

13 Hot Topics of MPLS Testing (2) Traffic Engineering! Achieve multi-vendor agreement about traffic engineering goals! Preferred methods of fast rerouting! How will devices with ATM-QoS and Ethernet-CoS interoperate? IP Packet! Verify redundancy, rerouting, protection switching function and performance! Check traffic engineering at the edge: DiffServ interworking with MPLS! How to run VPNs together with traffic engineering? IP Packet IP Packet IP Packet MPLS Network IP Packet

14 Hot Topics in MPLS Testing (3) Generalized MPLS Signalling! Implement MPLS in TDM, Lambda and Fiber switching! Achieve interoperability for GMPLS signalling! Verify interworking with packet-based MPLS switches! Prove that hierarchical tunnel models are interoperable! Determine GMPLS scalability and performance

15 Examining the work of the EANTC interoperability initiative! Goals! Benefits

16 Goals of Standardized Testing Status today:! Different test plans and approaches! Results of current interoperability tests cannot be compared! Quality of results depends very much on test plan and test report We see the need for standardized interoperability test guidelines Benefit for! Users and manufacturers! Comparable results! Less testing is needed

17 Interoperability Initiative Benefits for participants! Tests against latest MPLS implementations of other vendors check readiness for heterogeneous environments! Allow manufacturers of network equipment to verify implementations against different flavors of MPLS implementations! Vendors demonstrate their commitment to product quality assurance for network operators (users)! Get an impression whether protocol implementations are mature! Receive information about readiness of different features! Gain confidence that products will work in heterogeneous environment

18 Interoperability Initiatives EANTC EANTC is member of the MPLS Forum is an international forum! Members: Service Providers, Manufacturers, Test labs! Advancing the successful deployment of multi-vendor MPLS networks! Works on a guideline for Interop Testing

19 Test Areas Being Standardized Interoperability test areas! Signalling Protocols! Rerouting Mechanisms! Virtual Private Networks Joint Contribution of EANTC and the University of New Hampshire Interoperability Lab (IOL)

20 Conclusion Status of MPLS implementations:! Substantial number of large single-vendor BGP/MPLS VPNs in production use! Interoperability of basic protocols achieved Future test areas:! Evaluate VPN and Traffic Engineering interoperability in detail! Focus on service / application view for all test areas!! Performance and robustness tests become more and more important! Coordinated interoperability test methods will improve the benefit of test events worldwide! We expect that MPLS interoperability of important services Layer 2 / 3 VPNs and TE will be improved a lot in 2002
