Abstract: Systems and methods for managing virtual collaboration systems are disclosed herein. A virtual collaboration system includes a hoster configured to receive second media streams from at least a second node, and to transmit those streams from at least one simulated node to at least a first node; and a management subsystem adapted to dynamically configure a topology of a virtual collaborative event, wherein configuration of the topology includes a determination of media stream connections among the at least one simulated node and the at least a first node based on at least one policy, and wherein the media stream connections establish and maintain virtual relationships among the at least one simulated node and the at least a first node.

Abstract: A system of distributing node configuration information to a plurality of nodes in an event is provided. The system includes a first node, a second node operatively connected to the first node, and an event manager operatively connected to the first node and the second node. The event manager transmits the node configuration information to the first node and the second node, and transmits an indication to the first node and the second node to initiate communication between the first node and the second node using the node configuration information.

Abstract: An improved method is provided for validating network configuration change commands in a storage area network. The improved method includes: providing a change command to a network management device residing in the network, where the change command expresses a change to the configuration of the network and implicitly indicates an initial configuration state of the network therein; determining a current configuration state for the network; and implementing the change command when the change command is expressed in terms of the current configuration state of the network.
