Abstract: The paper embarks a retrieval methodology on the occurrence of a contingency to support a continuous transfer of data in the wired infrastructure of a virtual private network (VPN). The scheme envisages a new route between the source and destination in the architecture of a shared provider network to augment the disruption in the flow of traffic. It ensembles the minimum use of bandwidth in its formulation with a view to effectively avail the services and ensure a reliable delivery procedure. The philosophy bestows the creation of a viable alternate path in the form of a tree to carry forth the stream of data and acquire the best performance in terms of measurable indices. The results obtained through NS2 simulation illustrate the merits of the proposed strategy and emphasize its suitability for large scale transmission to meet the emerging needs.
Keywords: Bandwidth, Performance metrics, Tree routing, VPN.
