The Network API is implemented in the net.rim.device.api.io.transport and net.rim.device.api.io.transport.options packages. Most of the functionality is provided by the ConnectionFactory and TransportInfo classes. A ConnectionFactory object returns a ConnectionDescriptor object that contains a Connection object and information about the transport over which the connection was opened.
