光突发交换网络中带有可用性感知的快速恢复策略（英文）

Fast restoration strategy with availability aware in optical burst switching networks

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 congestion of backup path caused by the local deflection under the general restoration scheme,a fast restoration scheme based on availability of perception for optical burst switching networks is proposed. The proposed restoration scheme apperceive the availability of back link according to the feedback of the node status message,then the restoration nodes can make the retransmission of damaged service adjust the traffic according to the situation of link congestion. And it can effectively avoid the node congestion caused by simple retransmission. Through detailed descriptive analysis and a comprehensive simulation study,the scheme based on the availability of perception has better burst loss performance,a good service-distinction performance,and enhances the capabilities of high-priority service.
