A feedback mechanism based on randomly suppressed timer for ForCES protocol

Abstract

As the shortcomings of closed networks are high lightened, the requirements of next generation network for openness are becoming increasingly intense. Based on the fact that reliable multicast of ForCES protocol plays a significant role in improving the performance of ForCES router, this paper researches the congestion control within the reliable multicast process, and analyzes scalability issues of reliable multicast based on ForCES protocol. Also, this paper proposes a feedback mechanism based on randomly suppressed timer which effectively avoids the ack-implosion problem via analyzing a mathematical model of randomized procedure of multicast feedback process. According to the results of the test, this mechanism enables reliable multicast to better adapt to the instability of network environment.
