Research on Improved iSLIP Scheduling Algorithm Based on CIOQ Architecture
In order to improve the performance index and user service quality during data transmission,this paper studied the CIOQ architecture and the iSLIP scheduling algorithm,and proposed a PMQF_iSLIP scheduling algorithm that prioritized the number of matching queue cells to full load.The algorithm first judged whether the number of cells in the VOQ queue was equal to the set maximum capacity,and then executed different algorithm steps according to the judgment results.And finally we updated the priority of the matched ports that have been completed.In the next matc-hing,the port was given the priority matching authority.In the end,this paper simulated and analyzed the improved al-gorithm through the self-developed data exchange simulation platform.The simulation results show that:under the same traffic model,the improved algorithm reduces the packet loss rate and increases the throughput rate.
