Abstract: The article focused on the usage of Multiprotocol Label Switching (MPLS) over VOIP network. One of the features that MPLS has is Traffic Engineering (TE) which can help overcome potential pot holes in the network or to circumvent sub-optimal paths, especially in a network consisting of a diverse geographical terrain. The prevalence of MPLS IP VPN networks make them the de facto transport for inter-connecting IMS based VoIP devices. Inevitably, this creates the need for a fundamental set of guidelines, which can ensure that the quality of service for real time traffic is acceptable. To that end, a systematic approach was taken to implement traffic engineering LSPs which enabled the real time multimedia traffic to be delivered with highest priority and minimal loss and delay. This helped provide tangible network operations benefits such as, early detection of service disruption because of faults in the desired end to end label switched paths, reduction of the Mean Time to Resolve (MTTR) and lead to proposals for further improvements which could produce a more intelligent re-routing of the LSPs Keywords: Multiprotocol Label Switching (MPLS), Traffic Engineering (TE), Voice over Internet Protocol (VoIP), Internet Protocol (IP), Label Switched Path (LSP).
