The article presents a discussion on mobile virtual private networks (VPN). High-speed public internet access is starting to change the drill by offering opportunities to get and stay connected in more locations. Today, hotels that cater to business travelers frequently offer in-room high-speed internet access. Wireless LAN hotspots have surfaced in hotel lobbies, airport boarding areas, cafes and conference centers. Organizations often try to extend their existing remote aecess VPN solution to devices that connect over wireless. A number of wireless-aware products and features have come up. Some products focus on seamless roaming within privately-operated networks. On the other hand, mobile VPN products focus on roaming across diverse networks and managing differences in performance and cost associated with public networks. Mobile IP is just one approach used by some mobile VPN products. Detractors argue that Mobile IP is a high-overhead solution that adds to network infrastructure complexity. Proponents argue that Mobile IP is a standard that has undergone industry scrutiny and is well-positioned to leverage emerging IPv6 infrastructure. INSET: Executive Summary.
