Infonetics: MPLS-TP gaining carrier mindshare

At the end of a year in which transport-multiprotocol label switching (T-MPLS, known in standards circles as MPLS-TP for "transport profile), and provider backbone transport (PBT, otherwise known as PBB-TE, for provider backbone bridging-traffic engineering) battled for service provider dollars amid controversy, Infonetics Research has released what could be the definitive report on how carriers feel about these technology choices.

The report is called "MPLS-TP and PBB-TE Go Toe-to-Toe:Service Provider Survey," and comes after discussions with service provider decision makers between August and October of this year. The survey found that 80 percent of service providers are considering deploying MPLS-TP, even though the standard profile is not fully completed, while 53 percent are considering PBB-TE. Furthermore, about 32 percent of survey respondents said they will not consider-or have considered and rejected PBB-TE. Still, Michael Howard, principal analyst at Infonetics Research, said in the firm's press release announcing the survey results that PBB-TE is garnering enough interest that it has a "reasonable chance of being around for the long term."
