Implementation of hierarchical QoS mechanism on PBB-TE system

Abstract

This work investigates how hierarchical quality of service (QoS) could be realized in PBB-TE networks. The QoS mechanism is implemented using two rate three color marker (trTCM) and weighted fair queuing (WFQ) algorithms. We verify the performance of the QoS mechanism by measuring policing accuracies for four hierarchical QoS levels.
