Study of Traffic Control and Congestion Control in Broadband ISDN

摘要

In Broadband Integrated Services Digital Network (B-ISDN), the AsynchronousTransfer Mode (ATM) network architecture has been adopted as the switching and multiplexing scheme. One of the important ATM architectural issues is the traffic/congestion control. Numerous schemes, algorithms and theories have been studied in the area of network flow control, congestion control, and traffic control in order to seek suitable techniques to manage network traffic 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 referred to as Generic Flow 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 traffic flow at the Broadband Terminal Equipment (B-TEs) at an early stage before the traffic is transmitted into the network. This will have a significant role in the overall performance of high speed network traffic management.
