ASON中光路快速创建的方法

Method to Create Lightpath Fast in ASON

光路的快速创建在自动交换光网络(ASON)中具有重要意义,它有利于快速地提供业务和故障的快速恢复。从信令角度介绍了GMPLS在RSVP和CR-LDP基础上所做的一些扩展,包括上游建议标签和标签集,双向光路的创建,快速通告机制,波段交换,遇阻塞返回及反馈机制,给出了使用这些扩展建议来快速创建光路的方法。

To create light path fast is very important in ASON, it makes for fast service provision and fast restoration. From the signaling view, this paper introduces some extension of GMPLS based on RSVP and CR-LDP, including Suggested_Label and Label_Set objects, creation of bidirectional lightpath, fast notification mechanism, waveband switching, crankback and feedback mechanism, the paper gives the method to create lightpath fast to use these extension.
