Abstract

This paper proposes a new routing system for IP network traffic engineering. In this system, the link cost metrics are chosen to reflect the congestion level in terms of the number of flows traversing a given link as well as its residual bandwidth. This cost is used in the design of a dynamic routing for MPLS networks. At the same time, an optimal distribution of network flows is found, and used to impose a balanced traffic loading overall network links. This in turns, have led to a bounded network delay performance. Results have shown robustness of the proposed routing technique over networks with arbitrary topologies and heavy traffic demands.
