Flow and Congestion Control

H. Jonathan Chao, Xiaolei Guo

Abstract

Heavy congestion leads to severe delay and loss problems in packet networks. The basic objective of flow or congestion control in a network is to efficiently regulate the transient streams of sessions, in a decentralized manner, in order to avoid congestion in the network. The term “session” is used somewhat loosely to refer to any communication process to which flow control is applied. Chapter 7 begins with a comprehensive survey of the flow control and congestion control algorithms used in most networks. Subsequent sections address flow and congestion control mechanisms for ATM and packet networks, respectively. A link-by-link rate-based flow control scheme called EASY is also introduced.
