US 7,733,801 B2 · Network device management apparatus, network device management program, and network device management method

Abstract

A network device management apparatus which generates distribution routes for transmitting distribution information via communication devices, in order to distribute information to plural communication devices connected to a network, and makes the distribution information be transmitted in accordance with the generated distribution routes. The apparatus comprises: a hierarchy structure creation section that creates, based on units and the number of communication devices to which the distribution information is to be distributed, a hierarchy structure constituted by the units of communication devices as constitutional elements; and a distribution control section that controls distribution of the distribution information, by use of the hierarchy structure created by the hierarchy structure creation section. Therefore, the network device management apparatus can reduce the total distribution time and distribute information efficiently when the information is distributed to a huge number of communication devices.

Dependent claims

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
Σxi(where i=1 to y−1)≦n<Σxi(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.
