A system and method for storing data in a linked list memory architecture maintains several key list parameters. When data to be stored is received, a memory manager determines the list in which the data belongs and retrieves several of the parameters. The parameters retrieved indicate the address of the current location at which the received data is to be stored and the address of the next location that is to be linked to the current list. The memory manager writes the data to the current location pointed to by the first address and writes the second address into a pointer field in that current location. Because the address of the next location in the list is determined before data is written to the current location, this next address can be written in the same cycle in which the data is written.

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.
