PROBLEM TO BE SOLVED: To solve the problem that there is a risk that the updating of a program can not be received in the case that network equipment performs important processing and in the case that equipment is not activated and the operation of the network equipment stops in the case that a failure occurs at the time of updating. SOLUTION: When the network equipment 1 requests the updating of the program to the network equipment 3, the network equipment 2 managing the network equipment 3 tentatively preserves the updating request and generates the updating request to the network equipment 3. At the time of receiving the updating request, the network equipment 3 stops the present equipment in the case that a task operated on the present equipment is not important and updates the program. Also, the network equipment 3 acquires the updating request tentatively held by the network equipment 2 at the time of power supply, determines whether or not itself is activated, and the program is requested to the network equipment 2 in the case that it can not be activated.
