Abstract

Load balancing in a multimedia conference is disclosed, involving one or more internal terminals and one or more internal nodes separated from one or more external terminals and one or more external nodes by a firewall. Media data is forwarded through the firewall to at least a second one of the nodes, and received media data at the at least a second one of said nodes are processed. At a first event, reconfiguration is performed of said first one of said nodes to process received media data and of said second one of said nodes to forward received media data to said first one of said nodes. At a second event, loading is done of at least a part of said received media data being processed at the first one or second one of said nodes to at least a third one of said nodes.

Claims18

Dependent claims

A method for load balancing in a multimedia conference involving at least one internal terminal and at least one internal node separated from at least one external terminal and at least one external node by a firewall, wherein media data from at least one of one of the at least on internal terminal and at least one external terminal received at at least a first one of one of the at least one internal node and the at least one external node are forwarded through the firewall to at least a second one of one of the at least one internal node and the at least one external node, and received media data at the at least the second one of one of the at least one internal node and the at least one external node are processed by said second one of one of the at least one internal node and the at least one external node, comprising:

at a first event, reconfiguring said first one of one of the at least one internal node and the at least one external node to process received media data, and reconfiguring said second one of one of the at least one internal node and the at least one external node to forward received media data to said first one of one of the at least one internal node and the at least one external node;
at a second event, loading at least a part of said received media data being processed at one of the first one and second one of one of the at least one internal node and the at least one external node to at least a third one of one of the at least one internal node and the at least one external node;
and
standardized communication sessions according to one of H.323, Session Initiation Protocol (SIP) and WebRTC are only established between the at least one internal terminal and at least one internal node, and between the at least one external terminal and at least one external node, respectively, and forwarding of media data between one of the at least one internal node and the at least one external node are depending on standardized communication sessions.

1 more element

A node for load balancing in a multimedia conference involving at least one internal terminal and at least one internal node separated from at least one external terminals and at least one external node by a firewall, wherein media data from at least one of one of the at least on internal terminal and at least one external terminal received at at least a first one of one of the at least one internal node and at least one external node are forwarded through the firewall to at least a second one of one of the at least one internal node and at least one external node, and received media data at the at least a second one of one of the at least one internal node and at least one external node are processed by said second one of one of the at least one internal node and at least one external node, the node comprising input/output circuitry, a processor and a memory, said memory containing instructions executable by said processor whereby said node is configured to:

at a first event, reconfigure said first one of one of the at least one internal node and at least one external node to process received media data, and reconfigure said second one of one of the at least one internal node and at least one external node to forward received media data to said first one of one of the at least one internal node and at least one external node,
at a second event, load at least a part of said received media data being processed at one of the first one and second one of one of the at least one internal node and at least one external node to at least a third one of one of the at least one internal node and at least one external node;
and
standardized communication sessions according to one of H.323, Session Initiation Protocol (SIP) and WebRTC are only established between the at least one internal terminal and at least one internal node, and between the at least one external terminal and at least one external node, respectively, and forwarding of media data between one of the at least one internal node and the at least one external node are depending on standardized communication sessions.

1 more element

A computer readable medium comprising instructions for load balancing in a multimedia conference involving at least one internal terminal and at least one internal node separated from at least one external terminals and at least one external node by a firewall, wherein media data from at least one of one of the at least on internal terminal and at least one external terminal received at at least a first one of one of the at least one internal node and at least one external node are forwarded through the firewall to at least a second one of one of the at least one internal node and at least one external node, and received media data at the at least a second one of one of the at least one internal node and at least one external node are processed by said second one of one of the at least one internal node and at least one external node, the instructions, when executed on at least one processor, cause the processor to:

at a first event, reconfigure said first one of one of the at least one internal node and the at least one external node to process received media data, and reconfigure said second one of one of the at least one internal node and the at least one external node to forward received media data to said first one of one of the at least one internal node and the at least one external node;
at a second event, load at least a part of said received media data being processed at one of the first one and second one of one of the at least one internal node and the at least one external node to at least a third one of one of the at least one internal node and the at least one external node;
and
standardized communication sessions according to one of H.323, Session Initiation Protocol (SIP) and WebRTC are only established between the at least one internal terminal and at least one internal node, and between the at least one external terminal and at least one external node, respectively, and forwarding of media data between one of the at least one internal node and the at least one external node are depending on standardized communication sessions.
