Abstract:
1. A method for controlling a flow of packet data in a memory management unit of a network switch fabric, said method comprising: receiving a first portion of a data packet at a port on an ingress bus ring of the network switch fabric; determining a class of service for the data packet based on said first portion; storing said portion in a packer RAM of the port based on said class of service; storing subsequent portions of the data packet in the packer RAM; sending a predetermined number of portions to a packet pool RAM, once the predetermined number of portions have been received; sending, to a transaction queue, a reference pointer to a first predetermined number of portions to a transaction queue once an end of packet is detected; detecting a presence of a ready packet in the transaction queue by an egress scheduler and notifying an unpacker of the ready packet; putting the ready packet into a FIFO through the unpacker; and sending the ready packet to an ingress/egress module.
