摘要： A method according to one embodiment may include storing data in a send buffer. A transmission header may be created, in which the transmission header may include a pointer to the data in the send buffer. Packets may be transmitted, in which the packets include the transmission header and the data linked to the transmission header by the pointer, wherein the packets are transmitted without copying the data to create the packets. Of course, many alternatives, variations and modifications are possible without materially departing from this embodiment.

摘要： A method and apparatus for improving forwarding information base (FIB) lookup performance. An FIB is partitioned into a multiple portions that are distributed across segments of a multi-channel SRAM store to form a distributed FIB that is accessible to a network processor. Primary entries corresponding to a linked list of FIB entries are stored in a designated FIB portion. Secondary FIB entries are stored in other FIB portions (a portion of the secondary FIB entries may also be stored in the designated primary entry portion), enabling multiple FIB entries to be concurrently accessed via respective channels. A portion of the secondary FIB entries may also be stored in a secondary (e.g., DRAM) store. A depth level threshold is set to limit the number of accesses to a linked list of FIB entries by a network processor micro-engine thread, wherein an access depth that would exceed the threshold generates an exception that is handled by a separate execution thread to maintain line-rate throughput.
摘要翻译：一种用于改善转发信息库（FIB）查找性能的方法和装置。 FIB被分割成多个部分，分布在多通道SRAM存储器的段上，以形成可由网络处理器访问的分布式FIB。对应于FIB条目的链表的主条目存储在指定的FIB部分中。次FIB条目存储在其他FIB部分中（辅助FIB条目的一部分也可以存储在指定的主条目部分中），使得能够通过相应的信道同时访问多个FIB条目。辅助FIB条目的一部分也可以存储在次要（例如，DRAM）存储器中。设置深度级阈值以限制网络处理器微引擎线程对FIB条目的链接列表的访问次数，其中超过阈值的访问深度生成由单独的执行线程处理以维护的异常线速吞吐量。

摘要： Method and apparatus to support a large Internet Protocol Forwarding Information Base. A packet is received at a network device, the packet including a destination address. A table is indexed into using a portion of the destination address to locate an entry in the table associated with the portion of the destination address. A pool index is derived from the portion of the destination address and is used to identify a pool of data blocks from among a plurality of pools of data blocks. The entry and the pool of data blocks are navigated to find a next-hop for the packet.
