QoS约束下的两种多播路由协议比较

The Multicast Routing under QoS Constraints

具有QoS约束的多播路由协议是一种解决有QoS要求的多播应用的有效方式。本文主要介绍了QoS约束下的多播路由方式及所属的两种多播路由协议,从控制开销角度对YAM协议和QosMIC协议作了比较,并分析了各自的优缺点,在此基础上提出了对其进行改进的几点建议,并提出了QoS多播路由未来的研究方向。

QoS multicast routing is an efficient way to solve the problem of the multicast applications which require QoS constraints. This article mainly introduces multiple-path routing of the new joining ways into the multicast tree under QoS constraints. The agreement has assumed comparison from the angle controlling an expense to the YAM and QosMIC, which has analyzed the respective advantages and shortcomings, on its basis some suggestions are proposed to improve it. At last, the direction of the future development is pointed out.
