A In-order Queuing Parallel Packet Switch Solution Based on CICQ

The operating mechanism of PPS make the sequence of packets or cells about the same class can not be guaranteed in the output port. A In-order Queuing PPS Solution Based on CICQ is proposed in this paper, the solution can ensure the packets sequence for each traffic stream and ensure the packets have upper delay bound. Compared to the current mainstream PPS design, the solution is simple and easily implemented in hardware.
