基于占用率预测的QoS连接状态信息发布策略及其仿真研究

QoS link state advertisement policy and its simulation studies based on utilization prediction

提出了应用流量钳制方法,来控制网络内QoS路由的连接状态信息(LSA)发布量.仿真实验证明:在同样的LSA发布量情况下,与目前较为应用较为广泛的时间钳制方法相比,它可以获得更低的连结失败率和更高的资源利用率.根据流量钳制的特点,提出一种改进算法-占用率预测.实验证明该策略应用于流量钳制和时间钳制时,流量钳制获得了比后者更加明显的性能改善.

A clamp-down traffic method is proposed to control the volume of QoS link state advertisement （LSA）. The simulation results prove that by using the clamp-down traffic method, the higher network utilization efficiency and lower rate of link failures can be obtained comparing with the currently used clamp-down time method for the same LSA. Furthermore, a new method utilization prediction is proposed based on the characteristic of clamp-down traffic method. The results show that the clamp-down traffic method gets more characteristic improvements than the clamp-down timer method when using the utilization prediction.
