Abstract

"SISTEMA, DISPOSITIVO E MéTODO PARA GERENCIAMENTO DE PARTICIPAçõES EM GRUPOS DE MULTIDIFUSãO EM UMA REDE DE MULTIDIFUSãO". Um sistema (300,400,500), dispositivo (1200) e método (600) para gerenciamento de participações em grupos de multidifusão em uma rede de multidifusão utiliza dissimulação das transmissões de IGMP para consolidar as participações em grupos de multidifusão de diversos computadores principais em um computador principal de IGMP único. O agente de dissimulação das transmissões de IGMP mantém uma lista de grupo que indica a condição de participação em grupos de multidifusão dos diversos computadores principais de multidifusão. O agente de dissimulação das transmissões de IGMP estabelece uma participação em grupos de multidifusão com um dispositivo de multidifusão remoto quando pelo menos um dos diversos computadores principais de multidifusão solicita participação no grupo de multidifusão. O agente de dissimulação das transmissões de IGMP cancela o grupo de multidifusão com o dispositivo de multidifusão remoto quando todos os computadores principais de multidifusão tiverem abandonado o grupo de multidifusão. O agente de dissimulação das transmissões de IGMP responde às consultas sobre condição provenientes do dispositivo de multidifusão remoto como substituto representando diversos computadores principais de multidifusão."SYSTEM, DEVICE AND METHOD FOR THE MANAGEMENT OF PARTICIPATIONS IN MULTIDIFUSION GROUPS IN A MULTIDIFUSION NETWORK". A system (300,400,500), device (1200) and method (600) for managing memberships in multicast groups in a multicast network uses concealment of IGMP broadcasts to consolidate memberships in multicast groups from several main computers on one main computer single IGMP. The IGMP broadcast masking agent maintains a group list that indicates the condition of membership in multicast groups of the different multicast main computers. The IGMP broadcast masking agent establishes participation in multicast groups with a remote multicast device when at least one of the various multicast main computers requests participation in the multicast group. The IGMP broadcast masking agent cancels the multicast group with the remote multicast device when all the main multicast computers have left the multicast group. The IGMP broadcast masking agent responds to condition queries from the remote multicast device as a surrogate representing multiple primary multicast computers.
