Original Abstract

There is a trend that the integrated voice, real-time video and bulk data are together transported through the converged IP/MPLS (Internet Protocol/MultiProtocol Label Switching) core networks. The MPLS technology represents recent advanced way how to optimize and speed up the packet forwarding process in core networks. This paper introduces and evaluates the behaviour of MPLS technology in an experimental IP network with aim to find out the efficiency of the QoS (Quality of Service) mechanisms. The OPNET Modeler simulation environment is used to simulate the network scenario with QoS mechanisms implemented for voice traffic. This paper investigates the performance of the MPLS technology for traffic flows with varying QoS ratings.
