<p>PURPOSE:To constitute the system so that a repeating processing computer executes immediately a detour of a communication path at the time of fault occurrence by executing a communication path fault notice executed to one adjacent computer to the other adjacent computer. CONSTITUTION:A telegraphic message which a repeating processing computer 20 receives from an adjacent computer is delivered from a communication control means 21 to a path selecting means 28. When a destination computer number of the telegraphic message is that of the own repeating processing computer, a path managing means 23 delivers the telegraphic message to a telegraphic discriminating means 27. Unless the destination computer number of the telegraphic message is that of the own repeating processing computer, the path managing means 23 refers to destination path information 24 and selects a communication path of the highest priority being in a path useable state, and delivers the telegraphic message to the communication control means 21. In such a way, the repeating processing computer can send the telegraphic message to the adjacent computer of a communication path in which a fault is hot generated.</p> |
