  • Publication number: 20120300017
    Abstract: Media gateways (MGs), grouped into a hierarchy, are operable to provide a multiparty conferencing among client devices. Gateway resources such as processors, Codecs and network interfaces are aggregated at each MG to establish distributed connection sessions based on resource management metrics such as minimizing total network. The distributed connection sessions are utilized to provide the multiparty conferencing. Each MG may aggregate the gateway resources, which may be determined utilizing a look-up table, from other MGs for sharing among the MGs. Each MG may be activated to provide the media gateway controller (MGC) processing utilizing the shared aggregated gateway resources. A MG may be de-activated from the MGC processing when needed and the associated connection sessions may be subsequently released. Gateway resources are managed at each MG based on the resource management metrics in order to establish distributed connection sessions to support the multiparty conferencing among the client devices.
