Quality of service in a heterogeneous network

摘要

A network device provides priority map storage configured to store one or more mapping data structures for mapping multiple priorities of a first priority scheme to multiple priorities of a second priority scheme. In addition, mapping logic of the network devices is coupled to the priority map storage and configured to translate a first priority of a first frame of the first priority scheme to a second priority of the second priority scheme and to assign the second priority to a second frame carrying payload of the first frame in preparation of transmission of the second frame in accordance with the second priority scheme.

主权项

1. A network device comprising:
a first port for receiving frames; a second port for transmitting frames; and mapping logic coupled to priority map storage and configured to translate a first priority of a first frame of a first priority scheme to a second priority of a second priority scheme based on flow information of the first frame, wherein the flow information includes at least one of a source address and a destination address, wherein the first priority scheme is supported by a first network protocol and the second priority scheme is supported by a second, different network protocol and the network device maps between the first and second priority schemes of each network protocol in a heterogeneous network.
