چکیده

Avec l’augmentation du traffic dans les réseaux IP et les contraintes en termes de disponibilité imposées par les clients, les opérateurs de grands réseaux doivent utilisent des techniques d’ingénierie de traffic et de reroutage local. Nous proposons une méthode d’ingénierie de traffic par optimisation des poids des liens dans un réseau OSPF qui minimise la charge des liens et maximise les possibilités de reroutage local avec la technique des Loop-Free-Alternates. Notre méthode est implémentée en COMET et son évaluation montre qu’elle est aussi efficace qu’une implémentation optimisée de la méthode de Fortz & Thorup.

IP Fast ReRoute: Lightweight Not-Via

In order for IP to become a fulledged carrier-grade transport technology, a native IP failure-recovery scheme is necessary that can correct failures in the order of milliseconds. IP Fast ReRoute (IPFRR) intends to ll this gap, providing fast, local and proactive handling of failures right in the IP layer. Building on experiences and extensive measurement results collected with a prototype imple...

A Comparison between Two Post-Failure Load Distribution Techniques with Multiple Routing Configurations

When a link fails in an IP network, the network re-converges to redirect the traffic away from the failed link. IP fast reroute is used to minimize the time taken to redirect the traffic to an alternate path. Multiple routing configurations (MRC) is the IP fast reroute scheme under consideration. In this paper, we will discuss how to minimize the impact of the MRC recovery process on the post f...

10 Traffic Engineering

Traffic engineering and fast reroute are the two major applications of constraint based routing Traffic engineering is the process of controlling how traffic flows through a service provider’s network so as to optimize resource utilization and network performance[1]. Traffic engineering is needed in the Internet mainly because the shortest path is used in current intradomain routing protocols (...

Leveraging MPLS Fast ReRoute Paths for Distributed Green Traffic Engineering

This paper introduces a new scheme called Green MPLS Fast ReRoute (GMFRR) for enabling energy aware traffic engineering. The scheme intelligently exploits backup label switched paths, originally used for failure protection, in order to achieve energy saving during the normal failure-free operation period. GMFRR works in an online and distributed fashion where each router periodically monitors i...

Efficient Distributed Solution for MPLS Fast Reroute

As service providers move more applications to their IP/MPLS (Multiple Protocol Label Switching) networks, rapid restoration upon failure becomes more and more crucial. Recently MPLS fast reroute has attracted lots of attention as it was designed to meet the needs of real-time applications, such as voice over IP. MPLS fast reroute achieves rapid restoration by computing and signaling backup lab...
