Flow and Congestion Control
H. Jonathan Chao, Xiaolei Guo · 2001
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.
