摘要

PURPOSE:To correct the entire node information in a network by a single time operation for correction. CONSTITUTION:This node communication state managing device is provided with a reception packet identification part 2 for detecting a connection setting request to the same node issued during the communication of the certain node, a timer 6 for measuring the length of a period without the connection setting request to the node and detecting that the length exceeds the period set beforehand and a transmission packet generation part 4 for generating information that the node is during the communication and informing the entire nodes in the network of the information when the reception packet identification part 2 detects the connection setting request to the same node during the communication of the node.
