Performance evaluation of a novel redundancy method for videoconferencing traffic in MPLS networks

Abstract: Performance evaluation of computer networks using mathematical modelling is widely used in assessing the advantages and drawbacks of any new mechanism before its deployment. In this contribution, we introduce a new mechanism that aims at rerouting multi-point to multi-point (MP2MP) traffic such as videoconferencing in multi-protocol label switching-traffic engineering (MPLS-TE) networks. Then we develop a stochastic model in order to evaluate the amelioration incurred by our proposal compared to the existing approaches. In particular, we assess two criterions: the scalability and bandwidth efficiency. Our results show that our proposed method leads to better scalability while reducing the ratio of bandwidth wastage such as traffic duplication observed in the existing mechanisms. Our proposed rerouting mechanism contains two parts. First, we define the concept of MP2MP TE tunnel in MPLS as opposed to the existing MP2MP connectionless tunnel (i.e., without support of TE features such as bandwidth reservation and fast reroute in case of link and/or node failure). Second, we explain how to build a MP2MP TE bypass tunnel that is how to encapsulate a primary MP2MP TE tunnel into a backup MP2MP TE tunnel in order to provide the fast redundancy feature.
