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?

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

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

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

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
