Almost all service providers world wide have now deployed some MPLS service. And following in their footsteps, now many enterprises are also deploying MPLS. These deployment services range from IP+ATM, Layer 3 VPN - often with QoS, Traffic Engineering, TE Fast Reroute to Layer 2 VPN. This presentation will provide an overview of some service provider and enterprise deployments.

Cisco Systems, Inc. has played a large role in the success of MPLS enhancements to IP. Cisco was the first vendor to supply MPLS in Q2 1998 and now has over 250 customer deployments worldwide. A customer deployment profile by service will also be provided.

The first deployments were for the IP+ATM service. That service enabled service providers with ATM switches running IOS or some other operating system to forward IP packets via MPLS labels using the vpi/vci field.

The IP+ATM deployments were soon followed by TE and then L3VPN deployments, using BGP. And today, L3VPN is present in most of our customer deployments. Further, a large number of our L3VPN customers, also run MPLS QoS.

Following these MPLS capabilities, TE Fast Reroute (FRR) for link, node and shared risk link group (SRLG) protection have been released. Several customers have deployed TE to mange their bandwidth and several have deployed TE FRR link and SRLG to provide bandwidth protection. In some cases FRR has been used to replace 50 ms Sonet APS.

Most recently, we've released AToM (Any Transport over MPLS), an L2VPN capability. AToM customer deployment are also growing.

The purpose of this presentation, is to provide customer deployment examples of the above MPLS capabilities, demonstrating the many different ways MPLS improves IP today. Of course, there are many MPLS inventions underway and yet to be done. These will yield even more deployments for applications such as voice over IP, video conferencing, video multicast.
