一种无连接QoS路由机制
A connectionless QoS routing mechanism
摘要
Abstract
In order to provide quality of service (QoS) routing for the next generation Internet (NGI), a connectionless QoS routing mechanism is proposed, which includes admission control, extended intra-domain and inter-domain protocols. Probe packets and feedback packets are devised to accomplish admission control. A historical information statistics-based prediction scheme and a network congestion state perception scheme are introduced to improve admission control correctness and accuracy. By extending the open shortest path first version 3 (OSPFv3) protocol, QoS information is acquired, spread, stored and updated. And an extended Dijkstra algorithm based on the weighted fitting metric is proposed. By extending BGP4 + (Border Gateway Protocol 4 + ), the QoS property is added for path, and the routing decision process is modified. Experimental results show that the proposed connectionless QoS routing mechanism is practical and effective with better extendibility.关键词
