Patent ID: 7406088

Claim:
An interworking device for supporting service interworking between an Ethernet communication network and an ATM network, the service interworking device comprising: a first network interface operable to communicate with the Ethernet communication network using an Ethernet communication protocol; a second network interface operable to communicate with the ATM communication network using an ATM protocol; and a processing unit in communication with the first network interface and the second network interface, the processing unit: terminating frames received from a one of the ATM communication network and the Ethernet communication network; mapping parameters corresponding to the received one of the ATM and Ethernet frames into the other of the ATM and Ethernet frames, the mapped parameters including connection configuration control plane information and data plane parameters corresponding to individual frames, the connection configuration control plane information including at least one of connection mapping information, class of service mapping information, and traffic parameters information; determining a correction factor to map data rates between the Ethernet frames and the ATM frames; and using traffic parameters from one of the ATM and Ethernet networks to calculate traffic parameters for the other of the ATM and Ethernet networks.
