Abstract: A SD-PRPS (distributed packet by packet rate proportional server for K channels based on signal) scheduling algorithm was proposed. It could load the input flow over the multiple channels averagely. It was proved that the scheme can provide end to end delay to conformant traffic as packet-based generalized processor sharing(PGPS) and PRPS. The performance of SD-PRPS was studied using simulations and compared to worst-case fair weighted fair queueing (WF2Q). The simulations show that the delay performance of SD-PRPS is better than WF2Q with decreasing flow rate.
