Dynamic grooming, is it really dynamic?

The aim of dynamic grooming solutions is the efficient use of optical and IP resources in a layered network, that supports dynamically arriving connection or flow requests. Although in the last decade several algorithms were proposed and studied, none of them were analyzed from an important point of view: are they really dynamic? In our paper we introduce some metrics that help to observe the changes of the resource usage in a network with dynamic grooming. Several previously introduced algorithm were taken under the scope and our simulation results show, that they work in really dynamic way only in the very low load case. We also compared their performance with solutions, where the IP topology is static and an adaptive routing is applied to route the user traffic.
