System for identifying new client and allocating bandwidth thereto by monitoring transmission of message received periodically from client computers informing of their current status

摘要

Client computers on a computer network send messages informing their management computer on the network of the status of transmissions such as those for conferences involving the client computers. Managers use the messages to maintain records of active transmissions to (1) discover transmissions that started without explicit authorization from the managers and (2) delete transmission records corresponding to transmissions that terminated without explicitly notifying the managers.
