摘要
在分析了组合输入输出排队结构的基础上,对传统CIOQ(CombinedInputOutputQueued)的输出队列进行扩展和在内部交换结构中采用并行传送的方式,实现了交换调度的分布式操作和内部无加速的CIOQ交换;又通过将输出队列的状态信息反压到输入端和在输出端采取基于整包调度的算法,实现了对变长分组的交换,减小了定长信元交换中分组切割和重组的开销。
By extending the output queue(OQ) in traditional Combined Input-Output Queued(CIOQ) and using parallel transmission method in the internal switching architecture, the switching fabric could work in non-speedup with distributed operation of scheduling. By feeding the OQ's state back into the input, the switching architecture was able to fit for variable packets, and the expenses caused by segmentation and reassembling the packets in cell-based switching fabric were decreased.
