Multimedia Traffic Routing in Multilayer WDM Networks

Angela Amphawan, Mohd Amirol Md Khair, Hassanuddin Hasan


The advent of real-time multimedia services over the Internet has stimulated new technologies for expanding the information carrying capacity of optical network backbones.  Multilayer wavelength division multiplexing (WDM) packet switching is an emerging technology for increasing the bandwidth of

optical networks.  Two algorithms for the routing of the multimedia traffic flows were applied:         (i) Capacitated Shortest Path First (CSPF) routing, which minimizes the distance of each flow linking the given source and destination nodes and satisfying capacity constraints; and (ii) Flow Deviation Algorithm (FDA) routing, which minimizes the network-wide average packet delay.
