Abstract

A service is disclosed that discovers information about the logical networks to which a computer is connected and provides that information to applications. The information is keyed to names constructed by the service. There is a mapping between the names and the logical networks. Applications may rely on the names when selecting a configuration to use with a given logical network. The network name may be correlated with other information, such as physical network interface(s) on the computer through which the logical network is accessible, application programming interfaces of the transport protocols supported by the logical network, and the connectivity type of the logical network. Applications are notified when network information provided to them changes or when new information becomes available.

Claims

1. A method for providing network connectivity information to an application running on a computing device, the method comprising:

gaining connectivity to a network;

discovering aspects of the network;

associating a first name with the network, the first name unique within the context of the computing device;

providing the first name to the application as a key for accessing the discovered aspects of the network;

losing connectivity to the network;

regaining connectivity to the network;

rediscovering aspects of the network;

associating a second name with the network, wherein the second name is the same as the first name; and

correlating the first name with application programming interfaces of transport protocols supported by the network for identifying the computer'"'"'s logical network attachments.
