Transport Profile MPLS-TP Who can benefit?
Some Service Providers are focusing on transporting data (wholesale, SDH migration etc).
Flows are well defined and predictable
IP/MPLS is very flexible – Traffic Engineering could be used.
How it could be done simpler? MPLS-TP is the answer
Network and Service Management
