Abstract

There has been a dramatic increase in interactive cloud based software applications.

Compared to classical real-time media applications

(voice over IP (VoIP)/conferencing) and non real-time file delivery,

these interactive software applications have unique characteristics:

  1. They are delay sensitive yet demand in order and reliable data delivery,

and 2) the traffic is usually bursty.

Traditional window based congestion control does not work well

for interactive applications because the bursty arrival of data leads to

bursty network traffic, which causes additional queuing delay and packet

loss in the network which reduces its delay performance.

In this paper, we propose a new hybrid window plus rate

based congestion control technique. This algorithm improves the delay

performance of interactive applications by preventing

congestion induced loss and minimizing queuing delay while still

fully utilizing network capacity and maintaining fairness across multiple flows.
