ABSTRACT:
Methods and systems for caching packets to improve utilization of packet memory are disclosed. In one method, packets to be written to a packet memory are accumulated in write caches on an egress queue basis. That is, each write cache stores packets corresponding to an egress queue in the system. When one of the queues has a size that corresponds to a burst length of the packet memory, the packets are written from the queue to the packet memory. Packets are read from the packet memory to read caches. Subsequent accesses to packets stored in the read caches avoid the need to access the packet memory.
