Enhancements for Connecting Remote Users and Networks in Windows 7

Windows 7 builds on the foundation of Windows Vista by adding new features and enhancing existing features used for connecting remote users and networks. These improvements include the following:

• Support for a new tunneling protocol called Internet Key Exchange version 2 (IKEv2)
• Support for Mobility and Multihoming Protocol for Internet Key Exchange (MOBIKE), an extension of IKEv2 that allows VPN connections to change their reachable addresses without reestablishing security associations (SAs)
• VPN Reconnect, a new feature of Windows 7 and Windows Server 2008 R2 that uses IKEv2 and MOBIKE to provide automatic and seamless switchover of an active VPN connection whenever the underlying Internet connection changes
• Automatic fallback to Secure Socket Tunneling Protocol (SSTP) when an IKEv2 connection is attempted and fails
• Integration of remote access and VPN connections into the View Available Networks user interface (UI) to provide an improved connection dialing experience
• Support for allowing administrators to select the certificate to use for server authentication in SSTP
• DirectAccess, a new feature of Windows 7 and Windows Server 2008 R2 that provides users with the experience of being seamlessly connected to the corporate network from any location where they have Internet access
• BranchCache, a new feature of Windows 7 and Windows Server 2008 R2 that allows content from file servers and Web servers at a central office to be cached on computers at a local branch office, thus improving application response time and reducing wide area network (WAN) traffic
• Enhancements to the Remote Desktop Protocol (RDP) that improve the performance and quality of user experience for Remote Desktop sessions
• Mobile Broadband, which makes it easy to connect Windows 7 computers to the Internet using a wireless data card regardless of the cellular provider being used.
