Study of traffic control and congestion control in broadband ISDN
1992
In Broadband Integrated Services Digital Network (B-ISDN), the Asynchronous Transfer Mode (ATM) network architecture has been adopted as the switching and multiplexing scheme.One of the important ATM architectural issues is trafBc and congestion control.Many schemes, algorithms and theories have been studied for network flow control, congestion control, and trafBc control in order to find suitable techniques to manage network trafBc effectively to meet the quality of service requirement for network users.Among B-ISDN terminals in a Customer Premises Network (CPN) domain, a new flow control concept refered to as Generic Row Control (GFC), has been adopted and its protocol standardization is under study.The main purpose of GFC is to control and to schedule the local trafBc flow at the Broadband Terminal Equipment (B-TEs) at an early stage before the traffic is transmitted into the netwoiic.This will have a significant role in the overall performance of high speed network trafBc management.This paper presents a general overview of trafBc control as well as congestion control, related topics and issues currently under study.It is also a survey of publicly addressed techniques and algorithms used in B-ISDN networics, and report on status of the ANSI Accredited Standards Committee TlSl and CCITT standardization activities.The objective of this paper is to provide concrete concepts of ATM layer traffic/congestion control and to contribute technical studies to the standardization efforts in the traffic control and congestion control areas, particularly in ATM layer trafBc and congestion control issues in B-ISDN.•'<
