Abstract
A method and system for interworking between an Ethernet communication network and a frame relay network, in which a first network interface is operable to communicate with the Ethernet communication network using an Ethernet communication protocol. A second network interface is operable to communicate with the frame relay communication network using a frame relay protocol. A processing unit is in communication with the first network interface and the second network interface, in which the processing unit encapsulates frames received from the Ethernet network into frame relay frames, decapsulates frames received from the frame relay network to recover Ethernet frames and maps parameters corresponding to the received one of the frame relay and Ethernet frames into the other of the frame relay and Ethernet frames, the mapped parameters including connection configuration control plane information and data plane parameters corresponding to individual frames.
