ITU bellheads and IETF netheads clash over transport networks
Over the past few days, a long-simmering disagreement between the ITU-T and the IETF over a management protocol for telecom-operator networks erupted into the open. The technology at the heart of the dispute is operations and management (OAM) for Transport MPLS. T-MPLS refers to an adaptation of the Internet Engineering Task Force (IETF)'s MPLS protocol to telecom networks. MPLS can carry packets of different types, exactly what telecom operators need to offer private connections as well as regular IPv4 and IPv6 over a unified backbone.
