Performance of Two Dimensional Tunneling for Secure Data Transmission in Vpn

Jayanthi Gokulakrishnan, V. Thulasi Bai

Abstract :

A VPN is a private network that uses a public network "usually the Internet" to connect remote sites or users together. VPNs provide the ability for two offices to communicate with each other in such a way that it looks like theyre directly connected over a private leased line Instead of using a dedicated line for the communication between two parties across the globe, a VPN uses "virtual" connections routed through the Internet from the companys private network to the remote site or employee. One of the most important solutions to viruses and hackers threats is VPN that makes the network between companies and users secured; it is also authenticated and encrypted for security. The communication between the end to end nodes takes place in three phases: tunneling phase, decryption phase and authentication phase. In the tunneling phase, the data is tunneled with a special identification code of nodes and sends to authenticated nodes. All the intermediate nodes once again tunnel the nodes and send towards the destination. The number of tunneling increases with the increase of point to point communication. Intermediate VPN allows decode the data structure to a certain range. Thus this technique efficiently allows the packet to be transmitted with ensured security. In this paper, the performance of secure tunneling is evaluated with certain attributes like block size, tunneling delay, throughput, packet loss etc. with respect to Border Gateway Protocol.
