78 IETF, Maastricht, Netherlands MPLS-TP Use Case and Design Considerations draft-fang-mpls-tp-use-cases-and-design-01.txt Luyuan Fang lufang@cisco.com Nabil Bitar nabil.bitar@verizon.co Raymond Zhang raymond.zhang@bt.com Masahiro DAIKOKU ms-daikoku@kddi.com July 28, 2010 78 IETF, Maastricht, Netherlands

Objectives and Status Objectives: Provide MPLS-TP use case studies Serve as best practice guide with network design considerations Intended category: Informational Status: 00 and 01 draft issued before IETF 78 Plan to issue 02 draft right after IETF 78 Present in IETF 78 MPLS WG

Draft Outline Overview of MPLS-TP base functions MPLS-TP development principles Data Plane Control Plane OAM Survivability MPLS-TP Use Case Studies Mobile Backhaul Metro Access and Aggregation Packet Optical Transport Network Design Considerations IP/MPLS vs. MPLS-TP Standards compliance Delay and delay variation General network design considerations

Key points for design considerations MPLS-TP is part of MPLS With subset of existing features and extended to new features Unified MPLS solutions MPLS-TP extensions address transport specific needs Flexibility to combine IP/MPLS with MPLS-TP MPLS-TP and MPLS inter-operability Data plane: same as MPLS today OAM: using MPLS OAM as foundation General design considerations Operational experience Multi-service support? LTE consideration Network Inter-connections Network evolution path Performance management

Next Steps Call for volunteers to work together Collect comments/input from WGs Issue 02 draft after IETF 78 5
