| 摘 要： | 在动态、复杂的光网络传输系统中,提前预留作为保证网络服务质量的重要手段而被广泛应用。通过分析光网络环境下现有提前预留机制对生存性的影响因素,结合光网络中存在的脆弱链路问题,提出了一种基于生存性的资源提前预留机制及其模型。仿真结果表明,该机制可在保证资源利用率的情况下降低网络阻塞率,提高网络生存性。

| Abstract: | In the dynamic and complex optical network transmission system,resources advance reservation is an important means to ensure network quality of service which has been widely used.Through analyzing the factor that influences on the survivability existing resources advance reservation in the dynamic and complex optical network and combining with the fragile link,a resource reservation mechanism and model based on survivability was proposed.Simulation result shows that this mechanism can decline call blocking ... |
