Abstract

In this paper we present a comparison among three different monitoring functions to be used in a dynamic bandwidth renegotiation scheme. These functions aim at detecting the amount of unused resources in the network, which can be allocated to low priority data flows. These applications are not delay-sensitive and can be admitted by the call admission control with a bandwidth smaller than the nominal one. Simulation results comparing the performance of the three monitoring functions are presented, as well as an overhead analysis. Finally, we discuss the performance/complexity trade-off considering the three functions and determine the most viable one.
