ABSTRACT
A large number of simultaneous connections can be supported in a link of an optical network, using the multiplexing technique. In an optical network, a route that communicates emitter/destination must use the same channel λ for all the links in the route. A generalized Multi-Protocol Label Switching (MPLS) is a set of technical specifications of how MPLS would work under different technologies in the network, for example, the optical networks. There are three types of optical fibers depending on the diameter of the core and its refraction index. They are step index multimode fiber, graded index multimode fiber and step index monomode fiber. The chapter presents a real multi-objective scheme to minimize the functions number of λ, attenuation, and delay for unicast and multicast transmissions.
