+Network (VPN) technologies, such as Internet Protocol
+Security (IPSec), Layer Two Tunneling Protocol
+(L2TP), and Point to Point Tunneling Protocol (PPTP).
+Furthermore, the VPN solution of the Austrian
+company phion Information Technologies is presented.
+After a short introduction to the basics of each
+protocol, the strengths and weaknesses of each
+technology are outlined, as far as interoperability,
+manageability, and practical problems is concerned.
+This is done by means of a practical analysis and
+comparison of the results. The analysis includes
+performance measurement, link quality and stability
+analysis, feature comparison, interaction with TCP/IP
+protocols, and some basic security attacks. In order to
+provide comparable results, all technologies were
+tested in the same manner. However, this paper does
+not provide explicit recommendations which technology
+is to be preferred.},

   Abstract                 = {A virtual private network (VPN) can help resolve many of the issues associated with today's private networks. A VPN facilitates an agile IT infrastructure. Global VPNs enable connectivity to all locations anywhere in the world at a fraction of the cost of dedicated links. VPN services enable remote access to the intranet at significantly lower cost, thus enabling support for a mobile workforce. Additionally, the VPN architecture support a reliable authentication mechanism to provide easy access to the intranet from anywhere using any available access media including analog modems, ISDN, cable modems, DSL and wireless. There are primarily three types of VPN services: (1) local area network (LAN) interconnect VPN services, (2) dial-up VPN services, and (3) Ethernet VPN services},
