摘要： Techniques are described herein that may be used to invalidate all entries in a table. For example, the table may be a flow cache. For example, an expiry time may be associated with one or more entries in the table. The expiry time of an entry may be initially set to the sum of the system time, the expiry time of the protocol associated with the entry, and a global time variable. To check if the entry is expired at any time, the current system time may be added to the global time variable and if the result is greater than the expiry time in the entry, then the entry is expired. To invalidate all the entries, the global time variable may be incremented by a large amount which may equal the maximum expiry time of all protocols. This may cause all entries to expire. New entries may be added using the new incremented value of the global time variable and will hence not expire.

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.

摘要： A system and method to implement cell-based queue management in software. Packets are received from a packet-based medium. In response, packet pointers are enqueued into a virtual output queue (“VOQ”). When a dequeue request to dequeue a cell for the VOQ is received, one of the packet pointers is speculatively prefetched from the VOQ. A cell is then transmitted onto a cell-based fabric containing at least a portion of one of the packets received from the medium and designated by a current packet pointer from among the packet pointers of the VOQ.

摘要： Bandwidth is allocated by leveraging a bursty characteristic of data transmission signals to efficiently utilize network resources. Network performance is observed over a time period to identify patterns of data transmission rates as different signals are processed. To compensate for the fact that different jobs/tasks peak at different times, the total bandwidth limit may be increased by a scaling factor. The scaling factor is calculated using information obtained by observing network performance during the time period. The scaling factor is used to increase the total bandwidth available for all jobs/tasks executing during the time period without exceeding any bandwidth limits. The data transmission rate of each job/task may then be adjusted to utilize the newly available bandwidth.
摘要翻译：通过利用数据传输信号的突发特性来分配带宽以有效地利用网络资源。在一段时间内观察网络性能，以识别处理不同信号的数据传输速率的模式。为了补偿不同作业/任务在不同时间达到峰值的事实，可以通过缩放因子来增加总带宽限制。使用通过在该时间段期间观察网络性能获得的信息来计算缩放因子。缩放因子用于增加在该时间段内执行的所有作业/任务可用的总带宽，而不超过任何带宽限制。然后可以调整每个作业/任务的数据传输速率以利用新可用的带宽。

摘要： Techniques for optimizing queuing performance include passing, from a ring having M slots, one or more enqueue requests and one or more dequeue requests to a queue manager, and determining whether the ring is full, and if the ring is full, sending only an enqueue request to the queue manager when one of the M slots is next available, otherwise, sending both an enqueue request and a dequeue request to the queue manager.
