Currently Metropolitan Area Optical Networks are still based on SDH/SONET technologies. The disadvantages of such a rigid SDH/SONET rate hierarchy, especially when data applications such as Ethernet are considered, were soon realized. At the same time fast, link setup and release, and dynamic increase and decrease of the link bandwidth will be the scene of the future network. In order to meet the new requirements, the future network will combine with ASON/GMPLS, which is just the protocol to provide the basic function of topology and resource discovery and fast connection provision with intelligence. In this paper we discuss the new technologies and their combination in metropolitan area networks.
