Ahmed A. Method of optimization of Flows distribution in computer networks with technology of MPLS

The dissertation is dedicated to distribution and investigation of methods and algorithms of optimal flows distribution in computer network with MPLS (multi-protocol label switching). This main goal is to raise the efficiency of the utilization of communication resources.The problem of flows distribution in MPLS networks is formulated and mathematical model is constructed. The method of optimal flows distribution in MPLS networks is elaborated which enables to choose routes and find flows distribution of different classes under the constraints in the given values of QoS (quality of service) – mean packet delay and ratio of lost packets. The problem of capacities assignment and optimal flows distribution in MPLS networks is formulated and the corresponding algorithm was suggested which enables simultaneously to choose channels capacities and to distribute the flows of different classes under the constraints on QoS – mean packets delay and packet loss ratio. The experimental investigations of the suggested methods and algorithms were carried out, and the comparison with known methods of flows distribution, elaborated for ATM networks, was performed.
