A study of encrypted, tunneling models in virtual private networks

The concept of virtual private networks offers a simple and cheap alternative to dedicated secure networks in corporate networks and Internet environments. The choice, however, of authentication and encryption techniques and protocols affect issues such as data throughput and performance throughout the network. This paper looks into two virtual private network models within a corporate network. Two operating system platforms are implemented in this investigation; Novell Netware and Windows 2000. Performance of the two arrangements is, subsequently, analyzed and evaluated.
