ITU’s recent announcement on an OAM standard for MPLS in transport networks has seen considerable interest, but not always for the right reasons with claims from the Internet Society that it will jeopardize the Internet.
Experts cast doubt on ISOC’s statement: “… ongoing evolution along this path will jeopardize the … Internet”.
They point to the fact that several interoperability tests have been successfully performed with no reported problems. In addition the solution being proposed by ITU conforms to the MPLS-TP architecture as defined by the IETF. When network equipment uses different protocols, interoperability of the functioning of that protocol, in this case OAM, may well be affected. However, since packets for different protocols are identified by pre-assigned different codepoints, protocols running behind these different codepoints will not interfere with each other. This means that the core functionality – in this case Internet traffic – will not be affected. Therefore various protocols can coexist without causing any confusion in the network.
