Abstract
Preemption in Multiprotocol Label Switching (MPLS) is an optional traffic engineering technique used to create a new path of high priority when there is not enough bandwidth available. In such case the path is admitted by removing one or more previously allocated paths of lower priority. As there are usually many possible sets of low priority paths which can be selected, a preemption algorithm is being started to select the best possible combination to be removed. In this paper we investigate if there is any influence of network topology on the performance of two different preemption algorithms. We perform series of simulations to check the performance of two preemption methods in several models of real backbone telecommunication networks.
