The MPLS Forum
An industry-wide association of networking and
telecommunication companies focused on advancing
the deployment of multi-vendor Multi-protocol
Label Switching (MPLS) networks and associated
applications

Why is this a good idea ?MPLS key concepts

• An architectural change to IP
• Greatly enhances IP routing
• Clean separation of forwarding, routing and
  control signaling
• Single simple forwarding paradigm (label
  switching)
• Multiple routing and signaling protocols
  appropriate to purpose
• Including connection establishment protocols for
  Explicit paths
• Packet Classification mapping to Forwarding
  Equivalent Class
• Very flexibly and only once at ingress,
• Forwarding hierarchy
• Multiple link realizations (ATM, POS, Ethernet,
  Frame relay)
• Mainly being developed within the IETF

Voice Over MPLS Implementation Agreement

• Published in July of 2001, the Implementation
  Agreement (IA 0001) is the first produced by the
  MPLS Forum.
• The MPLS Forum defines VoMPLS as voice traffic
  carried directly over MPLS without IP
  encapsulation of the voice packet
• Work submitted as a liaison to both SG 11 and SG
  13 of ITU-T

15
Applications and deployment group

• Extension to VoMPLS work
• AAL2 over MPLS
• Narrowband services over MPLS
• Carrying other services over MPLS
• Frame relay over MPLS joint project with Frame
  Relay Forum
• ATM over MPLS extensions joint projects with
  ATM Forum
• TDM over MPLS
• MPLS UNI
• PVC and SVC service interface definitions for CPE
  and CLE
• MPLS support of Class and Quality of service

16
Interoperability Group

• Interoperability specifications for all the major
  protocols
• LDP
• RSVP-TE
• CR-LDP
• Etc
• Being written in conjunction with most of the
  major testing labs and test equipment vendors

MPLS and the ITU-T

• Study Groups Involvement
• SG11 MPLS Signaling
• SG13 MPLS IP VPNs and IP over ATM
• SG15 IP and MPLS Equipment Requirements
• Key Initiatives Today in SG11
• TRQ.MSoMPLS Multi-service over MPLS Signalling
  Req.
• TRQ.BBSoMPLS Broadband Bearer Services over
  MPLS Signalling Req.
• TRQ.NBSoMPLS Narrowband Bearer Services over
  MPLS Signalling Req.

19
MPLS and the ITU-T

• Key Initiatives Today in SG13
• Approved Y.1310 for IP over ATM Public Data
  Networks (recommends the use of MPLS Networks)
• Draft Y.1311 IP VPNs Generic Architecture and
  Service Requirements
• Draft Y.1311.1 Network-Based IP VPN over MPLS
  Architecture
• Draft Y.1710 (former Y.17oam.1) Requirements for
  OAM Functionality for MPLS Network
• Draft Y.1711 (former Y.17oam.1) Mechanisms for
  OAM Functionality for MPLS Networks
• Draft Y.1720 (former Y.17ps) Protection
  Switching for MPLS Networks
• New SG 13 work item approved on VoMPLS
• Requirements, Service Definition, Framework
  Architecture, User Plane Protocol, and
  Interworking

20
MPLS Forum and the ITU-T

• The MPLS Forum board is delighted to have
  established a good working relationship with the
  ITU-T
• Established a relationship under ITU-T Rec A.4.
• Recently received confirmation of a relationship
  under ITU-T A.5 to allow referencing MPLS Forum
  documents

21
Areas for collaboration

• IP/MPLS technology is relevant to much wider
  deployment than simply in the Internet
• It is possibly the basis for communications
  infrastructures in general.
• ITU-T has a vital role in using its long
  experience to ensure the needs of multi-service
  providers are fully met by developments in this
  technology
• In doing so collaboration with SDOs and Forums
  with specific expertise will clearly help speed
  up this process
• Very clearly there is a role in achieving
  co-ordination and co-operation between SDOs and
  Forums.
