SYSTEM AND METHOD FOR TRACKING ACTIVE CLIENTS IN WIRELESS MULTICAST NETWORK

摘要

A SYSTEM (100) AND METHOD (10) FOR TRACKING ACTIVE WIRELESS CLIENTS (160) IN A WIRELESS MULTICAST NETWORK, COMPRISING A WIRED INTERFACE (110) MEANS FOR ESTABLISHING NETWORK CONNECTIONS TO A PLURALITY OF EXTERNAL NETWORKS, A MULTICAST MODULE (120) MEANS FOR PROCESSING MULTICAST STREAM RECEIVED FROM THE WIRED INTERFACE (110), A MULTICAST TRANSLATION TABLE (130) MEANS FOR STORING THE ADDRESSES OF A PLURALITY OF ACTIVE WIRELESS CLIENTS (160) AND CONVERSION TABLE FOR CONVERTING INCOMING MULTICAST STREAM TO OUTGOING UNICAST STREAM, A RESPONSE-REQUEST GENERATOR MODULE (140) MEANS FOR PERIODICALLY TRANSMITTING A PLURALITY OF RESPONSE-REQUEST MESSAGES TO THE PLURALITY OF WIRELESS CLIENTS (160), AND A WIRELESS INTERFACE (150) MEANS FOR ESTABLISHING WIRELESS NETWORK CONNECTIONS WITH THE PLURALITY OF WIRELESS CLIENTS (160) AND TRANSMITTING UNICAST STREAM.
