MPLS Proposal Spawns IETF, ITU Turf War
Carolyn Duffy Marsan writes on NetworkWorld:
The Internet Engineering Task Force (IETF) is at odds with the International Telecommunication Union (ITU) over a special transport network architecture the ITU’s Telecommunication Standardization Sector (ITU-T) is developing to allow Multiprotocol Label Switching (MPLS) traffic to run over an Ethernet backbone. Among the network equipment vendors that have been contributing to the development are Alcatel-Lucent, Ericsson, Fujitsu and Tellabs.More here.
The problem, according to the IETF, is that the ITU’s Transport-MPLS (T-MPLS) specification will not work with the billions of dollars in routers and switches that carriers have installed in recent years based on the IETF’s MPLS standards.
"The situation is catastrophic," says Stewart Bryant, IETF liaison to the ITU-T on MPLS issues and a technical leader at Cisco. "There’s a fundamental opportunity for a major train wreck" between the IETF's MPLS and the ITU-T’s T-MPLS.
