摘要：GMPLS grew out of MPLS, a packet-switching technology designed to improve the efficiency of data networks. In this paper, we discuss the GMPLS technology, analyze its application. GMPLS is an advanced protocol which is essential for managing a diverse and complex network, because service deployment and service provisioning are manual, lengthy and costly processes. GMPLS has caused technical challenges in its deployment in optical networks. These challenges can be generalized into two areas: label assignment and wavelength conversion capability. In regard to wavelength conversion, which is correlated to routing problems. The inability of the optical switch to perform wavelength conversion has yielded a routing problem. The incompatibility of optical devices has violated the algorithms of path determination. It results in a high blocking factor call a long the path and high latency; these would eventually prejudice the performance of optical networks. ? 2010 IEEE.
