2. 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

3. 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

4. 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

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