CIOQ-based variable packet switches
Shuqi Zhang · Jisuanji gongcheng · 2005
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.
