Download optimization in the presence of multicast data

摘要

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.

1. A method for downloading data to an electronic data processing unit (EDPU) that is currently receiving multicast data through a router included in a network, the multicast data corresponding to at least one multicast data group, the method comprising:
determining that a download is to be received for use by the EDPU; sensing a receipt of multicast data so as to identify group numbers of the multicast data; recording in a list the multicast group number for each multicast data that is received; for each multicast group number in the list, sending an Internet Group Management Protocol (IGMP) Leave Group Messages on the network line; and ignoring IGMP Membership Queries issued by the router so as to cause the router to terminate a transmission of the multicast data to increase bandwidth for the download of the data.
