Performance of VoIP networks using MPLS traffic engineering

This conference paper was presented in the International Conference on Advanced Materials and Engineering Materials, ICAMEM2011; Shenyang, Liaoning; China; 22 November 2011 through 24 November 2011 [© 2012 Trans Tech Publications] The conference paper's definite version is available at: :http://dx.doi.org/10.4028/www.scientific.net/AMR.457-458.927The implementation of Voice over Internet Protocol (VoIP) technology is on the increase because of its ability to enhance operating efficiency and reduce infrastructure cost. Voice and data packets traverse over IP networks with fixed maximum capacity. But susceptibility to traffic congestion which results in delay and packet losses is still a major challenge of VoIP technology. Multiprotocol Label Switching Protocol (MPLS) with Traffic Engineering (TE) is an approved standard technology that has the capabilities to minimize network congestion and improve network performance by reducing delay and packet loss to yield a higher throughput. In this paper, we investigate how MPLS Traffic Engineering can be implemented to reduce traffic congestion on VoIP networks.Publishe
