摘　　要：LSP嵌套是ASON的一个重要特性,但GMPLS相关标准中缺乏对嵌套LSP的建立、拆除和维护过程的论述。首先分析了LSP嵌套关系模型,然后提出了一种用GMPLS RSVP-TE信令协议建立和删除嵌套LSP的方法,给出了详细的信令过程,并分析了删除嵌套LSP时屏蔽传送平面告警的方法。Nested LSP is an important characteristic in ASON, but there is no description of setting up, deleting and maintaining nested LSP in GMPLS related standards.Firstly, in this paper, a hierarchical relationship mod- el for nested LSP is analyzed.Then put forward a method of setting up and deleting nested LSP using GMPLS RSVP-TE signaling protocol.The detailed process of this method is given.A method of masking TP alarms during deleting nested LSP is also discussed.
