Point to Multipoint ABR Service Congestion Control Mechanism
Department of Electronic Engineering, Shanghai Jiaotong University, China
In ATM networks, ABR service is mainly used for data communication, and it adopts rate based congestion control mechanism. Under the point to multipoint communication environment, the key problem is how to merge the feedback information from leaf points in order to control the source rate to the minimum rate indicated by all the leaf points. This paper discusses the problems that the ABR mechanism meets and proposes criteria of evaluating the algorithms. It also analyses the characteristics of some existing algorithms, and proposes a new one. The performances between them are compared in terms of implementation complexity, response speed, scalability and merging noise.
