光网络实时连接恢复中资源分配死锁解除方法

Elimination methods of resource allocation deadlock for optical networking real-time connection restoration

智能光网络的到来,使光网络资源分布式并行分配死锁问题异常突出,对连接恢复的性能影响非常大。针对连接需要快速建立和恢复的特性,提出一种基于连接地址优先级的光网络资源分布式并行分配死锁解除方法,能够降低连接的建立和连接恢复的阻塞率,在高负载下可以缩短连接恢复的时间。

The arrival of intelligent optical networking highlighted the unusual issue of distributed parallel deadlock in the allocation of resources and impacted on the performance of connection restoration. As the need for the properties of fast connection establishment and restoration, an elimination method of the resource parallel and distributed allocation deadlock was proposed for the optical networking real-time connection restoration based on a connection address priority, which reduces the blocking rate of connection establishment and restoration and shorten the connection recovery time in the high load.
