The influence of proportional jitter and delay on end to end delay in differentiated service network
Thu Ngo Quynh, Holger Karl, Adam Wolisz, Klaus Rebensburg · 2002
There exist some studies in proportional scheduling algorithms for differentiated service networks which schedule the packets between different classes proportionally based on certain metrics, such as bandwidth, loss and delay. In this paper, the behaviors of RJPS (Relative Jitter Packet Scheduler) and another proportional delay scheduler (WTP), as well as its influence on the playout buffer, which uses the Concord delay adjustment algorithm, are examined. Our simulations show that RJPS is more convergent and produces a 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.
