Routing in multilayer optical networks can be made efficient if label switched paths are searched in a wavelength graph that represents the state and the switching facilities of the network devices very accurately. Maintaining the wavelength graph by using the conventional link state advertisement control mechanism leads to scalability problem. Much of the link state information is, however, redundant...
In this paper we describe a framework for internetworking heterogeneous high-performance networks. We believe GMPLS and Web services will be the proper technologies in such internetworking while the latter will be more widely accepted. We describe Web services for multi-layer, multi-domain topology description and advertisement, routing, path computation, and signaling functionalities as inspired...
