Quality of Service Performance Analysis of Voice over IP in Converged MPLS Networks

Abstract

The reliable delivery of packets is the major concern for the entire Internet service providers (ISPs) using Voice over internet protocols (VoIP). Therefore, quality of service (QoS) is a fundamental task for all VoIP using organizations. Unfortunately, there is no guaranteed way to ensure QoS, due to the fact that the QoS labels may be peeled off the packet while in the transition through various network elements. The performance of a network can be enhanced by Integrating QoS with internet protocol (IP) and multiprotocol label switching (MPLS) networks. In this paper we analyzed the QoS performance of VoIP in converged MPLS networks. Since IP systems are exceptionally dynamic, therefore progressive traffic monitoring and administration are needed before VoIP is even transmitted in a network infrastructure. This study provides a new configuration administration over an ISP network infrastructure comprised of converged networks carrying multiple VoIP instances. It is achieved using route reflectors and route redistribution at micro level to ensure a guaranteed threshold QoS at acceptance level in adverse circumstances.
