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.
