Traffic management and performance issues in asynchronous transmission mode (ATM) network

This paper discusses on performance issues of asynchronous transfer mode networks (ATM). in which conventional issues and new techniques have been studied and suggested. The whole discussion is based on improving the QoS, Quality of Service to increase the performance of ATM.QoS has been studied at connection-level, burst-level, cell-level. It discusses on congestion control. The approaches to QoS support of ATM networks are explained, several kinds of schemes such as CBR and ABR, weighted round robin and round robin, ERICA and EFCI are compared. Some simulation work is done and related results are shown and discussed.
