ABSTRACT:
A system and method for implementing quality of service features in a packet switch calculates quality of service parameters, and inserts these parameters into the packet header before the packet reaches the switch fabric itself. When a packet is received, errorcode processing takes place and the no longer needed error code is discarded. Packet header information is used to determine, via lookup table or other means, the service class and loss priority to be assigned to the packet. These parameters are inserted in the errorcode field of the packet header before the packet is provided to the switch fabric itself.
