代价自适应OSPF

Cost Adaptive OSPF

本文阐述了OSPF的基本特点 ,分析了由于业务会聚造成的网络局部拥塞问题。并对OSPF协议进行了改进 ,提出了代价自适应OSPF(CostAdaptiveOSPF ,CA_OSPF) ,CA_OSPF是对OSPF的兼容性扩展 ,运行CA_OSPF协议的路由器可以根据接口带宽的使用情况动态地调整接口的代价 ,从而实现网络负荷的均衡 ,提高网络的服务质量 (QoS)和资源利用率。文中详细阐述了CA_OSPF的基本思想 ,分析了仿真结果 ,并对CA_OSPF的性能进行了评价。

This paper expatiates on the basic characteristic of OSPF, and analyzes the local congestion issue of network owing to traffic aggregation. We improved OSPF and brought forward cost adaptive OSPF(CA_OSPF). CA_OSPF is a compatible expand of OSPF, a router running CA_OSPF may dynamically adjust its interface's cost according to the utilization ratio of the interface's bandwidth, as a result, the network's load is balanced, the network's QoS and resource utilization ratio are improved. This paper expatiates on the basic idea of CA_OSPF, analyzes the simulation result and appraises the performance of CA_OSPF.
