A method for generating and maintaining a pruned broadcast tree for a network of switches operating multiple simultaneously active paths between devices with a load balancing family of protocols. The pruned broadcast tree is preferably generated as a by product of cost propagation aspects of the load balancing protocols exchanged among cooperating network switches. The load balance protocols operable within the network switches in association with the present invention permit multiple simultaneously active paths to be utilized among the network devices. The pruned broadcast tree is therefore used to reduce the latency of broadcast messages propagated within the network switches to reach all devices in the network. The broadcast tree defines a minimized set of devices to which a broadcast message need be forward to assure transmission to all network devices. The pruned broadcast tree, once established, is updated only in response to failure of a link and recovery of a failed link. A separate protocol of the present invention enables such pruned broadcast tree modifications and restoration.

A collaboration network is defined by creating a virtual meeting room on a central server. The central server negotiates with one or more edge servers for remote management of selected collaboration parameters, which control such things as shared objects, group connections, streaming video, and video on-demand. Using the selected collaboration parameters, the edge servers manage the meeting participation of the network clients connected to the virtual meeting room through the individual edge servers. When management of the meeting participation requires either parameters that the edge server does not have or when the parameters of the edge server are out of date, the management responsibility is transferred to the central server for that request.

A real-time collaborative graphics application and method (such as Microsoft® Visio®) that runs on top of a collaborative networking platform (such as Microsoft® ConferenceXP) and provides real-time collaboration. The real-time collaborative graphics application and method personalizes local objects created by a local to readily distinguish them from remote objects created by remote users. Identifiers are used to allow the authorship of an object to be easily determined by all users. Local objects, remote objects, and a combination of the two can be moved and manipulated by any users. A local user may avoid sharing his local objects with remote users. Moreover, a local user can decide to hide remote objects created by remote users. If at a later time the local user decides to once again view the hidden remote objects, all updates since the remote shapes were hidden are automatically updated at the local user's document.

A system and method for distributing streaming content data from a server to multiple clients enables the server to handle transient surges of requests by having the clients cooperate with the server and other clients to distribute content, thereby alleviating the load on the server. The server divides the streaming content into multiple sub-streams (e.g., by using multiple description coding), and constructs multiple distribution trees with itself at the root and each client as a node in each of the trees. Each sub-stream is transmitted down a corresponding one of the distribution trees. Clients that receive sub-streams from its parent nodes in the distribution trees in turn forward the sub-streams to their child nodes in the trees.

Only participants that have the session identifier respond to the inquiring participant. Finally, communication is established between the participants that responded to the message and the inquiring participant. In this regard, a collaborative network is formed including the inquiring participant.

The present invention teaches a system and method for improved signal recovery for range and coverage extension in a heterogeneous cooperative network of digital chaos transmissions with OFDM component signal transmission. The invention improves upon the state of art in side channel information from the transmit side containing information on the clipped amplitude. In-band transmission of the side information is achieved by exploiting the sparsity of the resulting clip amplitude position with improved levels of compression over the prior art using Gabor Transform Multiple Symbol Encoding transmitter. The information rate of the clipped amplitude is sub-Nyquist relative to the original OFDM component signal transmission, which allows very low power spreading by a cooperative digital chaos sequences at a transmit side and recovery of the clipped amplitude at a receive side. Further, an improved noise resistance side channel performance is achieved by decoding Gabor Transform symbols for symbol recovery.
