Abstract

The average queue delay of optical packet increases when the packets block in the virtual output queue header in the asynchronous optical packet switching. We analyze the character of variable length Internet packet and propose the preemptive short packets priority (PSPP) algorithm for reducing the total packet waiting time in the queue. In the PSPP algorithm, the short packet can preempt the transmission time of the long packet and can be served first. The analysis and the simulation shows the PSPP algorithm can make the average waiting time of the short packet decrease to zero almost and can decrease the total packet average waiting time largely when the traffic load is middle and low. The PSPP can guarantee the low average waiting delay for the real time TCP traffic implementation.
