This paper attempts to develop a data transfer scheme with a view to sufficiently provision the hose model of the Virtual Private Network (VPN) and accomplish the desired degree of performance. The basic idea is to extract a service comparable to that of a private dedicated network with leased lines for the endpoints of the VPN. The service providers are expected to guarantee the required bandwidth, in order to address Quality of Service (QoS) issues while employing a VPN over a shared network. Thus a tree based mechanism is generated through which well defined resource management procedures are devised to optimize the available bandwidth. The data packets forwarded through such predetermined paths serve to ensure secure communication between customer sites.
