An another model called hose model, in which there is no need for a complete traffic matrix. But only the total amount of traffic which a node exerts into the network and the total amount of traffic which it receives from the network need to be specified in the model.
The main contribution of this paper is that blocking probability is compared for different over provisioning factors. Blocking probability is a measure of network performance. Apart from these, security and web services are indispensable factors involved in this work.

A Virtual Private Network (VPN) allows the provisioning of private network services for an organization or organizations over a public or shared infrastructure such as the internet or service provider backbone. VPNs are provisioned using technologies such as Frame Relay and Asynchronous Transfer Mode (ATM) and virtual circuits have been available for a long time, but over the past few years IP and Multi Protocol Label Switching (MPLS) based VPNs have become more and more popular. A VPN is a cheap source of tunneling, encryption, authentication, and access control technologies and services used to carry traffic over the internet or a managed IP network, or a providers backbone. In VPN technologies, a tunnel allows streams of data and associated user information to be transmitted over a shared network within a virtual pipe model. This pipe model makes the routed network totally transparent to users. In the pipe model it is necessary to calculate traffic matrix.An another model called hose model, in which there is no need for a complete traffic matrix. But only the total amount of traffic which a node exerts into the network and the total amount of traffic which it receives from the network need to be specified in the model.
The main contribution of this paper is that blocking probability is compared for different over provisioning factors. Blocking probability is a measure of network performance. Apart from these, security and web services are indispensable factors involved in this work.
