It is widely recognized that Traffic engineering (TE)mechanisms have to be added to the IP transportfunctionalities to provide QoS guarantees whileensuring efficient use of network resources. Trafficengineering is a network management technique whichroutes traffic to where bandwidth is available in thenetwork to achieve QoS agreements between current andfuture demands and the available network resources.Multi-path routing has been proven to be a moreefficient TE mechanism than Shortest Path First (SPF)routing in terms of profit maximization and resourceusage optimization. However the identification of setof paths over which traffic is forwarded from sourceto the destination and the distribution of trafficamong these paths are two issues that have beenwidely addressed by the IP community but remain anopen issue for the emerging generation IP networks.Building upon different frameworks, this workrevisits the issue of multi-path routing to presentand evaluate the performance of different...
