基于延时抖动趋势的分层组播方案
Layered Multicast Based on Delay-Jitter Trend
摘要
Abstract
Layered multicast is a promising solution to address the problem of multicast congestion control in heterogeneity network. However, schemes using this solution suffer from slow response time and lack of fairness, and induce a lot of loss by slow response and failed join experiments. In this paper we propose a new layered multicast based on delay-jitter trend (LM-DJT). LM-DJT introduces the delay-jitter trend model into an amended TCP throughput equation to estimate the TCP-friendly transmission rate, and each receiver adjusts its subscription layers according to the estimated transmission rate. Our simulation results show LM-DJT converges fast to the optimal layer of subscription, induces less loss to track the available bandwidth, and has inter-session fairness and TCP-friendliness.关键词
