中文摘要：
为了在智能光网络中应用预订机制,扩展了GMPLS相关协议。提出了最短路、链路权重变化和分层图三种路由波长分配算法,以及划分共享波长和非预订业务专有波长的机制。仿真表明,业务量较低时,分层图算法最优;为非预订业务保留专有波长可以在一定程度上改善其性能,但会较大程度地提高预订业务的阻塞率并降低资源利用率。
英文摘要：
To apply advance reservation in intelligent optical network, the related protocols of GMPLS were extended. Three routing and wavelength assignment algorithms, which were shortest path,link weight change and layered graph,were provided. Meanwhile a classification of shared wavelengths and dedicated wavelengths for non-advanced reservation was proposed. Simulations show layered graph is best with low traffic loads. Wavelength-dedicated mechanism can improve the performance of non-advance reservation to a certain degree,but it will cause the high block of advance reservation and inefficient resource utilization.
