The Impact Of Using Security Protocols In Dedicated Private Network And Virtual Private Network

Abstract With the development of computer networks techniques and the increased use of private networks the intrusion and attack on these networks also increased so the use of the protection protocols became necessary but using these protocols will reduce the quality of the performance of these networks. This research highlights the impact of using security protocols on two types of private networks. The OPNET version 14.0 has been used to simulate the two networks and to apply the different types of security protocols such as L2TPPPTP and IPsec.
