Abstract: A method, system, and computer program product are disclosed to manage multiple operating modes in a video conferencing network under which different sets of policies can operate. The system is a network management server, also referred to herein as the ELASTIC GATEKEEPER™, that includes a Conference Management System, which selectively implements one or more different sets of operating policies. The Conference Management System is integrated and linked with a gatekeeper, which is responsible for setting up calls that are using end point alias addresses. The gatekeeper works with the Conference Management System to control access to network resources. Upon receiving a request to access a call, the gatekeeper passes the request to the Conference Management System for its approval.

Abstract: Method, system, and computer program product example embodiments of the invention are disclosed to manage multiple network zones interconnected over a wide area network for video conferencing. In one example embodiment of the invention, an interface of a zone controller is configured to receive a first user request to schedule local resources for a video conferencing session within a local network zone. The zone controller is configured to access local services in the zone to schedule the local resources for the video conferencing session. The interface of the zone controller is further configured to receive a second user request to schedule remote resources in a remote network zone for the video conferencing session. A local Network Zone Manager in the zone controller is configured to determine a remote Network Zone Manager responsible for the remote resources in the remote network zone in response to the second user request.
