In the case of making communication through a transmission line provided among the plural processing means by means of a packet, when a processing means whose processing is busy of a specific node with service requests concentrated thereto receives a service request packet, a station address of a service extension destination node is added to a reply packet with respect to the arrived packet and the result is sent to a transmission line to allow a service request source to re-request the service to the extension service node.
