摘要： In a method for storing packets in a network device, a memory space spanning a plurality of external memory devices is partitioned into a plurality of multi-buffers. Each multi-buffer spans multiple memory devices in the plurality of external memory devices. Each multi-buffer is partitioned into a plurality of buffer chunks and the plurality of buffer chunks are distributed among the multiple memory devices Further, a packet is divided into one or more packet chunks including at least a first packet chunk. The one or more packet chunks are stored in one or more consecutive buffer chunks of at least a first multi-buffer of the plurality of multi-buffers.

摘要： An embodiment of the present invention reduces certain memory bandwidth requirements when sending a multicast message from a network device such as a router, bridge or switch. Separate output buffers are provided for different groups of egress ports, and incoming messages are written to some or all of the output buffers. A processing determination is made as to which egress ports will forward the message. Buffers associated with non-forwarding ports are released and the message is queued at the forwarding egress ports. When the message is forwarded, data is read from the output buffers associated with the forwarding egress ports.

摘要： Resources allocated to a group of ports include a plurality of storage regions. Each storage region includes a committed area and a shared area. A destination storage region is identified for a packet. A packet queuing engine stores the packet in the committed area of the determined destination storage region if it has a first drop precedence value, and if available storage space in the committed area exceeds a first threshold. The packet queuing engine stores the packet in the shared area of the determined destination storage region if the packet is not stored in the committed area, and if available storage space exceeds a second threshold defined by the packet's drop precedence value. If the packet is not stored either in the committed or shared area, it may be dropped.

摘要： A flow classifier for a network device that processes packets including packet headers includes a hash generator that generates hash index values from search keys derived from the packet headers. A hash table receives the hash index values and outputs pointers. A flow table includes flow keys and corresponding actions. A variable length (VL) trie data structure uses the pointers to locate the flow keys for the search keys. The VL trie data structure selects different flow keys for the search keys that share a common hash index value. The pointers include node, NIL and leaf pointers. The flow classifier performs a default action for the NIL pointers. A pointer calculator accesses a VL trie table using the pointers.
