ABSTRACT:
An apparatus and a method for realizing OAM function interworking between an Ethernet network and an MPLS network in network communication field. The method meets the challenge in realizing OAM functions when MPLS serves as a bearer network to bear Ethernet services, provides processing modes for all kinds of OAM functions. Based on the Ethernet-MPLS service interworking function model defined in Y.1415, interworking of Ethernet OAM functions defined in Y.17 ethoam and MPLS OAM functions defined in Y.1711 on network layer is realized, ensuring an end-to-end OAM interworking mechanism between Ethernet and MPLS networks. Processing modes for all kinds of OAM functions on the basis of the Ethernet-MPLS service interworking model in Y.1415 are provided, implementing end-to-end OAM interworking and improving communication continuity and safety between the Ethernet network and the MPLS network.
