Abstract
A network control system of one node of a communication network includes a data link stage and a session stage which provide a priority protocol. The network control system includes a storage and the data link stage stores received messages in the storage. When the number of stored messages reaches a predetermined limit, the data link stage limits the receipt of messages to priority messages. The session stage is arranged such that if it and a session stage of another node simultaneously initiate a session service, a connection is established, the session stage having a higher priority completes its session first, and the connection is maintained to permit the lower priority session stage to complete its session.
