Abstract:
There is provided a method for optimizing a download of requested data to an electronic data processing unit that is currently receiving unrequested multicast data through a router included in a network. The unrequested multicast data corresponds to at least one multicast data group. Internet Group Management Protocol (IGMP) V2 Leave Messages are sent to the router for the at least one multicast data group. IGMP Membership Queries issued by the router for the at least one multicast data group are ignored, so as to cause the router to terminate a transmission of the unrequested multicast data to free up available bandwidth for the download of the requested data.
