Impact of different link cost metrics on the performance of routing algorithms for traffic-engineered MPLS networks

Abstract

Absslracr-This paper assesses the idueaee of different link cost metries on the overall performance of muting algorithms, which are suitable for realizing traffic engineering in IP networks by means of MPLS (Multipmtocol Label Switching). The performance evaluation is conducted by mesm of extensive network simulations for a partially meshed network and three distributed muting algorithms, while the average end-to-end delay, total network throughput, and the total packet dmp pmbabilily are taken as performance measures. It is shown that the link cast metric selection affects the performance of the considered muting algorithms in terms of the typical traffic engineering goals.

PDMR: priority‐based dynamic multi‐path routing algorithm for a software defined network

“…design a multipath planning based on each hop routing architecture for IoT (Internet‐of‐Things) multimedia sensing [14], which cannot achieve the monitoring information of the global network. Accordingly, we have to consider the classification of the link cost function, a prioritised flow and the aggregation of bandwidth network resources based on dynamic multi‐path provisioning over SDN networks, which can effectively improve the utilisation of network resources according to the demand of different flows in different scenarios [15].…”
