Abstract
In a shared network such as the Internet, applications need to respond to network congestion indications to avoid congestion collapse, to improve network bandwidth utilization, and to share bandwidth fairly with competing applications. While TCP congestion control, the congestion control protocol in the current Internet, is appropriate for applications such as bulk data transfer, its rapid rate fluctuations do not work well with emerging applications such as streaming media applications.
In this talk, I will first present General AIMD congestion control (GAIMD), a congestion control scheme that allows an application to control both its long-term fairness behavior and its short-term transient behaviors. Then I will present a study of the transient behaviors of four TCP-friendly congestion control protocols. I will also discuss the issues of applying congestion control protocols to real-time applications and present algorithms to address the issues. At the end of my talk, I will also briefly summarize my work on multicast congestion control, and secure group key management.
