Novel schemes for traffic engineering in access domains

In this paper, our approach to tackling the problem of traffic engineering in access domains is discussed. The complete solution would take into account bandwidth management, allocation, de‐allocation, protection and restoration. In this work, we focus on one part of the problem, i.e. constrained routing in the MPLS access domains. We define all categories of traffic in an access domain and use CF (conjunction factor) as a figure of merit for performance evaluation of constrained routing schemes and present algorithms that control and limit CF value. The results of conducting simulations using various constrained routing algorithms are presented and conclusions are outlined. Copyright © 2006 John Wiley & Sons, Ltd.
