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

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
