This IETF RFC should delight all the people who complained that Frame Relay has no relevance to modern networking. I’ve always said that the point of frame relay in network studies is to tech the concepts of non-broadcast networking in point-to-point and point-to-multipoint configurations.
And, once again, RFC1925 Rule 11 is proven – “Every old idea will be proposed again with a different name and a different presentation, regardless of whether it works.”
The Multiprotocol Label Switching Transport Profile (MPLS-TP) is the common set of MPLS protocol functions defined to enable the construction and operation of packet transport networks. The MPLS-TP supports both point-to-point and point-to-multipoint transport paths. This document defines the elements and functions of the MPLS-TP architecture that are applicable specifically to supporting point-to-multipoint transport paths.
Like all MPLS-TP standards, this is RFC seems overly complex and doesn’t seem to explain why anyone would want to do this. I guess someone understands it, let me know if you know why this is relevant to networking.
