Packet switching is a rapid store-and-forward networking design that divides messages into arbitrary packets. Using this, a Virtual Private Network (VPN) is a secured way of connecting a Local Area Network (LAN) to another at a remote location. The VPN uses authentication to deny access to unauthorized users, and encryption to prevent unauthorized users from reading the private network packets. Normal Restoration algorithm (ARA) provides protection on disjoined nodes or paths from the point of failure to the destination. Provisioning & Restoration Algorithm (PRA) combines & optimises the capacity allocation on an end-to-end basis, to satisfy the QoS constraints. Better quality of service is achieved by PRA algorithms. The primary bandwidth is the one on the path under the non-failure case. The additional bandwidth are needed on the alternative paths under the node or link failure case. It is called protected bandwidth. A 20 steps algorithm in this research proposes a combination of the provisioning and restoration to achieve better results than the ones obtained by independent methods. What is next? It is Electronic Telepathy . A practical model is designed and proposed !!!
