Abstract
A node () for an MPLS telecommunications network has interfaces () for OAM information exchange relating to a path for data traffic, between first and second other nodes each operating according to different OAM state machines for OAM information exchange. An OAM state machine mapper () maps the states of either of the different OAM state machines of the first and second other nodes into states recognized by the other of the different OAM state machines. OAM information exchange is according to either the first or the second OAM state machine and according to states mapped from the other of the OAM state machines, to support the path for data traffic through the node. By such mapping of the different states OAM information can be exchanged across corresponding boundaries and so paths no longer need to be terminated at the boundary to enable end to end operations.
