The Influence of Proportional Jitter and Delay on End to End Delay in Differentiated Service Network

There exist some studies in Proportional Scheduling Algorithms for Differentiated Service Network which schedules the packets between different classes proportionally based on some metrics as bandwidth, loss, delay. In this paper, the behaviors of RJPS (Relative Jitter Packet Scheduler) and another proportional delay scheduler (WTP), as well as its influence at the Playout Buffer which uses Concord Delay Adjustment Algorithm are examined. Our simulations show that RJPS is more converging and produces smaller delay than WTP via the same network with the same loss rate. Finally, we propose a network using both RJPS and WTP for minimizing the network delay of each class.
