Big Need for MPLS-TP?

August, 2014

At the service providers across the globe, the most widespread and native selection is MPLS and not MPLS-TP. The former has broader acceptance, superior interoperability, and operational intimacy for the engineering folks. In Asia, particularly China, MPLS-TP has taken off in a big way. While some industry observers view that part of the world as exceptionally unpredictable and may suggest that “TP” could even be replaced, it seems that at least one of the large Chinese operators has such a critical mass of deployment that such a move is not imaginable. On its face, one would think customers should want to go with MPLS-TP over MPLS because the former is a newer version. Ordinarily, any supplier that would happen to start product development from scratch would definitely be inclined to begin in the “TP” direction.

In a Light Reading post in June, Orange appears to be discussing “all-IP” in a marketing context, not in a technical one. It is almost as if the headline could have been, “Stop the Presses – Orange Discovers Massive Number of Synchronous Optical Elements in its Network.” Of course, even with past projections by service providers years ago about moving to “all-IP,” which turned out to be inaccurate, there were SDH and AT ...
