Performance of traffic engineering in operational IP-networks: an experimental study
2005 (English)In: 5th IEEE International Workshop on IP Operations and Management, 2005, 202-211 p.Conference paper (Refereed)
Today, the main alternative for intra-domain traffic engineering in IP networks is to use different methods for setting the weights (and so decide upon the shortest-paths) in the routing protocols OSPF and IS-IS. In this paper we study how traffic engineering perform in real networks. We analyse different weight-setting methods and compare performance with the optimal solution given by a multi-commodity flow optimization problem. Further, we investigate their robustness in terms of how well they manage to cope with estimated traffic matrix data. For the evaluation we have access to net-work topology and traffic data from an operational IP network.
