Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for managing participant terminals in a network system, and more particularly to a distributed management method for performing distributed management and changing the distributed management form according to the increase or decrease of the participant terminals.
[0002]
[Prior art]
In the network connection, in order to perform mutual connection by connection using an IP address represented by an Internet telephone or the like, it is necessary that the partner computer is in a connectable state and the partner IP address is known. .
[0003]
Normally, the computer that provides the network system manages the ID, IP address, information indicating the connection status, and the like for identifying the participant terminals for performing the interconnection. At the time of registration for participation, the user was to register his / her own IP address in the computer that performs the above management.
[0004]
When a participant terminal of the network system connects to the other party, a unique name (ID) of the other party is searched from the managing computer, and the IP address of the ID of the search result is obtained, so that one-to-one connection is obtained. Or a one-to-many connection was made.
[0005]
FIG. 11 is a diagram showing a configuration of a conventional connection between networks.
[0006]
The network system 1101 is connected to participant terminals 1103A to 1103E representing a plurality of participant terminals and an administrator terminal 1102 for managing each participant terminal.
[0007]
From each of the participant terminals 1103A to 1103E to the administrator terminal 1102, an IP address allocated to each participant terminal when joining the network system 1101 and an ID for identifying a user who uses each participant terminal Are transmitted. The administrator terminal 1102 manages all the information of the participant terminals currently participating in the network system 1101, and introduces the currently participating participant terminals according to the contents of the inquiry from the participant terminals. Has functions.
[0008]
In the illustrated state, the information S1A sent from the participant terminal 1103A to the administrator terminal 1102 includes information sent when joining the network 1101 and an inquiry for searching for a partner. The administrator terminal 1102, which manages all the information of each participant terminal, sends the participant terminal 1103A information S2 that answers the participant terminal corresponding to the inquiry content included in the information S1A. The participant terminal 1103A interconnects with the participant terminal included in the information S2 by using the information S3.
[0009]
[Problems to be solved by the invention]
In the above-described conventional network system, information of all participant terminals is managed by the manager terminal. For example, if there are 100,000 participant terminals, it is necessary to process 100,000 participant terminal information at the manager terminal, which requires an extremely high-performance computer.
[0010]
The number of subscribers of the network system gradually increases from the start of the network system, and the number of participant terminals participating in the network simultaneously increases and decreases. For this reason, the performance required for the administrator terminal also varies.

On the other hand, in the case of distributed management using a plurality of small computers, the number of participant terminals to the network system increases and decreases as described above, and the scale of the participant terminal information is accordingly fluid. It is very difficult to manage the number of computers in a distributed manner. For example, when the number of participant terminals in the network system decreases, the number of computers becomes excessive in the initial number of computers, resulting in a total wasteful investment. Conversely, when the number of participant terminals in the network system increases, the capacity becomes insufficient with the initial number of computers.

【The invention's effect】
Since the present invention is configured as described above, it has the following effects.
[0132]
A network system is realized in which distributed management is performed according to the increase or decrease in participant terminal information. Even in a system having a large-scale participant terminal of about 1,000,000, the load on the system side is very small because the load is distributed to the participant terminals. When the number of participant terminals managed by each administrator terminal is set to be small, even if the participant terminals become administrator terminals, the load can be reduced.
[0133]
In addition, since a high-performance participant terminal is selected as the administrator terminal, a low-performance participant terminal does not need to execute the function of the administrator terminal, so that the load is small.
[0134]
Furthermore, since the administrator terminals are distributed, there is an effect that even if a failure occurs in several administrator terminals, the damage is reduced.
