Network device which intelligently filters redundant data streams within computer networks

An intermediate device, such as a router, can intelligently filter redundant data streams provided by one or more hosts. In the event of a network disturbance, the router may stop filtering one of the now needed redundant data streams in a manner that may reduce the consumption of network resources, such as bandwidth, without having to modify end-user applications residing on subscriber devices. Therefore, the router may transparently provide data streams to subscriber devices despite the occurrence of a network disturbance that may otherwise prevent the subscriber devices from receiving the data streams.
