<p>PURPOSE:To reduce the synchronous updating processing of routing information, and to suppress the distribution of information to the necessary minimum by updating automatically the routing information required for a telegraphic message relay processing, by each node is accordance with the change of the constitution of a network. CONSTITUTION:When the general relay executing part 3a of a relay node 1 searches a routing information store part 2, and obtains an adjacent node corresponding to an address node contained in a relay telegraphic message, the telegraphic message is relayed to the adjacent node, and also, a control is delivered to a processing executing part 3b except a general relay. The executing part 3b refers to a transmission origin node, checks whether it exists as an address node in the store part or not, and when it does not exist, the transmission origin node is registered in the store part 2. On the other hand, when 'there is no address node' as the result of search to the store part 2, the executing part 3a reserves the relay telegraphic message, and delivers a control to the executing part 3b. In such a case, the executing part 3b sends out an inquiry telegraphic message to a constitution management node 1'. In the node 1', a retrieval/answer executing part 4 retrieves a constituting information management base 5, and the latest routing information is answered.</p> |
