An increasing number of applications, such as audio and video conferencing, are using the internet as a communication backbone. In such applications it is important to minimize the latency of communication while extracting sufficient throughput. Existing applications tend to fill the internet with large amounts of data with the result that maximum throughput is achieved only at the cost of very high latency. In the case of packet switched networks there are large delays due to the presence of the routers in the path and due to the networks being shared. We have developed a protocol to control the latency for communications over the internet while holding throughput to an acceptable level and reducing jitter. The scheme is general and adaptive, so it can work with a variety of applications and protocols. An important aspect of our work is that it provides a possible solution for reducing latency in communications over the existing internet without using any additional hardware.
