Network Diagnostics Framework (NDF)
The ability to assist the user in diagnosing a network problem is expected to be a major new networking feature. There is extensive support for runtime diagnostics for both wired and wireless networks, including support for TCP Management information base (MIB)-II and better system event logging and tracing. The Vista TCP/IP stack also supports ESTATS which defines extended performance statistics for TCP and can help in determining the cause of network performance bottlenecks. Windows Vista can inform the user of most causes of network transmission failure, such as incorrect IP address, incorrect DNS and default gateway settings, gateway failure, port in use or blocked, receiver not ready, DHCP service not running, NetBIOS over TCP/IP name resolution failure etc. Transmission errors are also exhaustively logged, which can be analyzed to better find the cause of error. Windows Vista has a greater awareness of the network topology the host computer is in, using technologies such as Universal Plug and Play. With this new network awareness technology, Windows Vista can provide help to the user in fixing network issues or simply provide a graphical view of the perceived network configuration.

Famous quotes containing the words network and/or framework:
“A culture may be conceived as a network of beliefs and purposes in which any string in the net pulls and is pulled by the others, thus perpetually changing the configuration of the whole. If the cultural element called morals takes on a new shape, we must ask what other strings have pulled it out of line. It cannot be one solitary string, nor even the strings nearby, for the network is three-dimensional at least.”
—Jacques Barzun (b. 1907)
“Seeing our common-sense conceptual framework for mental phenomena as a theory brings a simple and unifying organization to most of the major topics in the philosophy of mind.”
—Paul M. Churchland (b. 1942)
