Virtual Private Network (VPN) protects information systems in enterprise organizations by building a security tunnel between the headquarters and branches, or from the headquarters to suppliers and customers. Proper and effective implementation can be evaluated by considering organizational effects and enterprise objectives. In this paper a research model is proposed to evaluate the performance...

A VPN establishes a secure network using the insecure media of the Internet. However, before a VPN can be established keys must be exchanged between the communicating peers. In this paper, we present the implementation details of the Arcanum key exchange protocol along with its experimental analysis. We simulated a number of active and passive attacks in order to test the robustness and efficie...

This paper explores an Internet-based VPN solution, built upon IPSec, which combines tunneling with PKI authentication and encryption. To protect the valuable company resources, an efficient intrusion/misuse detection and response system was incorporated into deployed security solution. This approach enabled a large-scale customer provide their global e-business safely. As a result, an integrat...

The VPN Tree Routing Conjecture states that there always exists an optimal solution to the symmetric Virtual Private Network Design (sVPND) problem where the paths between all terminals form a tree. Only recently, Hurkens, Keijsper, and Stougie gave a proof of this conjecture for the special case of ring networks. Their proof is based on a dual pair of linear programs and is somewhat involved. ...

This work is resulted from the effort on incorporating IP VPN services into a 10G Ethernet product for an industry vendor.

This document describes procedures for BGP MPLS-based Ethernet VPNs (EVPN). The procedures described here meet the requirements specified in RFC 7209 -"Requirements for Ethernet VPN (EVPN)".
