为了解决光突发交换网络中传统恢复机制简单转发造成备用路径拥塞的问题,提出了一种带有可用性感知的快速恢复策略。该策略根据反馈的节点状态信息感知链路的可用性,对转发的受损业务进行自适应调整,从而有效避免简单转发而导致的节点拥塞现象。仿真结果表明:带有可用性感知的快速恢复策略具有较好的丢包性能,很好地实现了业务区分,增强了网路对高优先级业务的恢复能力。
In order to solve the problem that the standby path is congested due to the simple forwarding of the traditional recovery mechanism in the optical burst switching network, a fast recovery strategy with usability awareness is proposed. The strategy perceives the link availability according to the fed-back node status information and adaptively adjusts the forwarded damaged traffic to avoid node congestion caused by simple forwarding. The simulation results show that the quick recovery strategy with usability awareness has good packet loss performance, well differentiated services and enhanced network resilience to high-priority services.
