Patent ID: 7733801

Claim:
A medium that has recorded therein, readably by a computer, a network device management program that causes the computer to execute a process comprising: creating a hierarchy structure constituted by units of communication devices so that the hierarchy structure is constructed from an uppermost level in order to minimize a value of x×y which satisfies the expression Σx i (where i =1 to y−1)≦n<Σx i (where i= 1 to y), where n is the number of the units of communication devices, x is the identical number of other units of communication devices than one of the units of communication devices through which information is to be distributed to the other units, and y is the number of layers constituting the hierarchy structure, the communication devices being connected to a network; and controlling each of the communication devices so as to distribute the information in order from a higher communication device indicated in the hierarchy structure created in the creating to a lower communication device indicated in the hierarchy structure.
