Abstract

DiffServ-aware MPLS-TE (DS-TE) significantly enhances the MPLS-TE architecture by enabling bandwidth reservation on a per-class basis. More specifically, to this aim, the so-called Bandwidth Constraint Models (BCMs) are introduced as a key architectural element. This paper describes a new NS2 module that offers a complete support for the DS-TE architecture including the standard BCMs (MAM and RDM) and a new BCM (G-RDM), recently proposed by the authors. Moreover, the paper shows the results of simulations carried out to evaluate the behaviour of the above mentioned BCMs in a real network scenario.
