Patent ID: 8665900

Claim:
An interworking device for maintaining quality of service parameters for transmissions as an Ethernet service between a first network having a first communication protocol and a second network having a second communication protocol that is different from the first communication protocol, the interworking device including: a first network interface configured to communicate with the first communication network using the first communication protocol; a second network interface configured to communicate with the second communication network using the second communication protocol; and a processor in communication with the first network interface and the second network interface, the processor configured to: receive frames from the first network in the first communication protocol; map at least one parameter corresponding to a quality of service bandwidth mapping parameter in the first communication protocol to at least one quality of service parameter in the second communication protocol, the at least one quality of service parameter in the second communication protocol being selected from a group consisting of token bucket size and token rate, the mapping of at least one parameter being based at least in part on a specified Ethernet Virtual Connection (EVC) bandwidth; and assemble data packets in the second communication protocol, the assembled data packets comprising at least one mapped quality of service parameter.
