And Control

Congestion is an un-avoiding issue of networking, and many attempts and mechanisms have been devised to avoid and control congestion in diverse ways. Random Early Discard (RED) is one of such type of algorithm that applies the techniques of Active Queue Management (AQM) to prevent and control congestion and to provide a range of Internet performance facilities. In this chapter, performance of RED algorithm has been measured from different point of views. RED works with Transmission Control Protocol (TCP), and since TCP has several variants, the authors investigated which versions of TCP behave well with RED in terms of few network parameters. Also, performance of RED has been compared with its counterpart Drop Tail algorithm. These statistics are immensely necessary to select the best protocol for Internet performance optimization.

This paper first introduces definition and cause for congestion control as well as TCP/IP congestion control mechanism, focusing on introducing active queue management arithmetic in IP congestion control mechanism, and points out its important function in congestion control. The method of active queue management arithmetic which solves full queue of routers is dropping arrived data packets before the queue is full so that end-note is able to respond before the queue overflows, avoiding the actual occurrence of congestion. RED arithmetic is a famous AQM arithmetic and congestion control based on control theory has become a new research focus.
