MESSAGE ROUTE SETTING METHOD FOR DISTRIBUTED NETWORK, AND NETWORK COMMUNICATION STATION

摘要

PROBLEM TO BE SOLVED: To detect a route inside a network, to send the message of route change inside the network and to take them under consideration. SOLUTION: In the method of message routing between stations inside the network, all the stations under consideration execute below-mentioned operations. Data including at least a message identifier (ID, ISS), the identifier (TSS) of a message transmission station and a message transmission cost (CT) are stored (E202 and E204). At the time of confirming the reception of at least two messages for which the message identifier (ID, ISS) matches and the identifier (TSS) of the transmission station is different (NO in E203), to the message transmission of a lower message transmission cost, a specified message (901 including updated routing data is transmitted (E207). In the meantime, the specified message is transmitted to the message transmission station of a higher message transmission cost as reception informing. By this invention, the alternation of the route inside the network is retrieved and taken into consideration.
