【摘要】 针对IP网络庞大复杂且资源信息频繁动态变化的事实,提出了一种扩展OSPF路由协议以支持QoS路由的算法。该算法根据用户需求资源的不同,在OSPF域中预先计算出到达各目的节点的最优路径,同时生成一个新的路由表,并通过链路状态广播机制,动态更新该路由表,以达到在对现有OSPF协议影响最小的情况下,引入QoS机制的目的。更多还原

【Abstract】 Considering the enormousness and complexity of IP networks and the frequently and dynamically changing of their resource information, this paper puts forward an algorithm extended from OSPF routing protocol to support QoS. According to the different resource requirement of users this algorithm pre-computes the most optimized path to each destination node in OSPF field, then builds a new route table. After that it updates that route table by link state broadcasting mechanism so as to introduce mechanism of QoS while minimizing the impact to current OSPF protocol.更多还原
