COMMUNICATION NETWORK CONTROL SYSTEM

摘要

PURPOSE:To attain efficiently the storage service of data by providing a file for transmission/reception in station unit and providing a common file having an overflow processing function to a network. CONSTITUTION:Transmission files 9a-9e and reception files 10a-10e provided in station unit are connected to nodes 3a-3e via control CPUs 8a-8e and the common file 7 having the overflow processing function is connected to a transmission line via managing CPU6 and a node 3f in the network where terminal devices 5a-5e are connected to the transmission line 1 via the nodes 3a-3e. Each station gets away from the state of overflow by reporting the presence of overflow to a destination terminal device of a received mail data and receives a data or the overflowed share again from the common file.
