Current State of Interoperability
Not fully tested yetImplementations are still proprietary to some extent
Traffic Engineering (RSVP-TE / CR-LDP)
Standards still under developmentLayer 2 VPNs
Only basic interoperability achieved; more implementations and protocol features become available
MPLS/BGP VPNs
Good interoperability achieved for basic protocol functions
Signalling protocols LDP and RSVP-TE
StatusArea
European Advanced Networking Test Center
Current State SummaryBasic Interoperability between different vendors -
demonstrated at several events! Basic interoperability tests necessary only to
guarantee that existing and new implementationswork 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?
European Advanced Networking Test Center
Deployment of MPLS NetworksRecent 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

Hot Topics and future test areas for the development of full interoperable multi vendor networks
European Advanced Networking Test Center
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)
European Advanced Networking Test Center
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?! 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?

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
European Advanced Networking Test Center
Examining the work of theEANTC interoperabilityinitiative! Goals! Benefits
European Advanced Networking Test Center
Goals of Standardized TestingStatus 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
European Advanced Networking Test Center
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
European Advanced Networking Test Center
Interoperability Initiatives EANTCEANTC 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
European Advanced Networking Test Center
Test Areas Being StandardizedInteroperability test areas
! Signalling Protocols! Rerouting Mechanisms! Virtual Private Networks
Joint Contribution of EANTC and the University of New HampshireInteroperability Lab (IOL)
European Advanced Networking Test Center
ConclusionStatus of MPLS implementations:
! Substantial number of large single-vendor BGP/MPLS VPNs in production use
! Interoperability of basic protocols achievedFuture 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
