A system and method are provided wherein information is disseminated using a reliable IP multicast network implementation coupled with dynamically assigned proxy nodes serving as zonal aggregation points. These nodes share information with each other over the reliable IP multicast network, augmenting this function with a reliable point-to-point communication infrastructure between proxy nodes in those instances where IP multicast is not available or prone to error.

Method, apparatus, system, and article of manufacture for reliable low-bandwidth information delivery across mixed-mode unicast and multicast networks

Distributed convergence nodes referred to as 'Supernodes', embodied as a functional technology component within an end user application, automatically determine whether said component should become 'active' and assume the responsibility of forwarding IP multicast data present on a LAN (which supports IP multicast communication) to a &#x201c;Routing Supernode&#x201d; via a WAN (which does not support IP multicast communication). The Routing Supernode, in turn, is responsible for forwarding that traffic to other Supernodes present on other LANs. The traffic sent to and from the Routing Supernode is sent via unicast communication. All Supernodes are responsible for forwarding traffic on their respective LAN across the WAN to a Routing Supernode, and for forwarding traffic received over the WAN from the Routing Supernode onto their own respective LANs. An election process determines which device in a LAN is to operate as a SuperNode.

Method, apparatus, system, and article of manufacture for providing distributed convergence nodes in a communication network environment

A system, apparatus, article of manufacture, and method provides one or more distributed convergence nodes referred to as 'Supernodes', each of which is embodied as a functional technology component within an application that automatically determines whether said component should become 'active' and assume the responsibility of forwarding IP multicast data present on a LAN (which supports IP multicast communication) to a &#x201c;Routing Supernode&#x201d; via a WAN (which does not support IP multicast communication). The Routing Supernode, in turn, is responsible for forwarding that traffic to other Supernodes present on other LANs. The traffic sent to and from the Routing Supernode is sent via unicast communication. All Supernodes are responsible not only for forwarding traffic present on their respective LAN across the WAN to a Routing Supernode, but they are also responsible for forwarding traffic received over the WAN from the Routing Supernode onto their own respective LANs. An election process determines which device in a LAN is to operate as a SuperNode.

A system and method is described for establishing a homogenized communications infrastructure that enables a variety of disparate communication devices to communicate transparently with each other over a computer data network. The system and method allow for such communications to take place by converting all communications from all participants in the form of audio, video, textual, and binary data messages into discrete data units that are carried over a computer data network. These communications are propagated to other participants by relay to their particular devices in such a way that individual participants are insulated from the type and implementation of all other participants' devices.
