Abstract

A method and system for 'selective' tunneling of streaming data from a server to a client in a computer network having one or more network segments. The server has a tunneler utility, and the client has a receiver utility. The receiver utility first attempts to detect if a given data stream is available via IP multicast on the network segment supporting the client. If not, then the receiver utility issues a request for a IP unicast stream. This request is serviced by the tunneler utility. The tunneler utility re-broadcasts the IP multicast feed using IP unicast to send the data stream directly to the requesting user and/or to a repeater utility. The receiver utility then receives and processes the data stream for output to the end user. Alternatively, the receiver application, or a network administrator, launches the repeater utility, which then converts the IP unicast stream back to IP multicast format for re-broadcast over the network segment to other clients.
