摘　　要：通用多协议标签交换技术(GMPLS)在光交换网中具有广阔的应用前景,但对它的研究还不够深入。首先指出GMPLS与传统的标签交换技术(MPLS)在7个方面的区别,然后刻画GMPLS光网络的一般结构,对特点进行了分析,指出光IP包交换的实质是光标记的转发与交换。设计了GMPLS光网络的技术方案,对关键技术进行分析,提出了一种基于波长变换的光标记技术,以及通过MPLS标记栈实现LSP分级。采用这样的技术集成方案,能够充分发挥GMPLS的优势,实现IP与WAM的完美结合。Generalized multi-protocol label s witching（GMPLS） has a promising future in optical switching technology. However, there are only a few investigations on GMPLS. We pointed out the differences between GMPLS and traditional MPLS firstly, then depicted the principle structure of GMPLS, and identified that the transfer and switching of the optical label is essential to optical IP packet. We put forward a solution of GMPLS optical switching net, and proposed a optical labeling technology based on wave length transform and LSP with MPLS label stack. In this solution, the combination of IP and WAV is achieved with the advantage of GMPLS.
