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 terminates frames received from a one of the frame relay communication network and the Ethernet communication network 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 include circuit configuration control plane information and data plane parameters corresponding to individual frames.
