Member information and history information of a user of a network computer terminal subscribed as a member are stored.

In the content server 10, the content driving engine 40 is to execute various web content services for a network computer terminal connected to the contents server 10 online. When the web content service is a network game service in which advertisement contents are displayed, a game execution application program mounted in each network computer terminal is operated to execute an operation for managing the game progress.

In addition, the distributed processing management program 50 of the content server 10 checks the line speed of a plurality of network computer terminals connected to the website 30 of the corresponding content server 10 through an internet communication network, By selecting a network computer terminal having a line speed of and registering as a sub server substituting the corresponding content server 10, the other network computer terminal is distributed to the network computer terminal registered as each sub server in a distributed manner. It functions to receive web content service through server.

Here, in the content server 10 equipped with the distributed processing management program 50, the line speed is increased for each setting area among a plurality of network computer terminals connected online in the predetermined setting areas A1 to An through an internet communication network. The network computer terminal (COMA1 to COMAn) checked at the fastest speed is selected and registered as a sub server. The circuit for the network computer terminal newly connected in each setting area is registered even when the sub server is registered. By continuously performing the speed check, if a network computer terminal having a faster line speed exists even if a predetermined network computer terminal is already registered as a sub server in each setting area, the network computer terminal is newly registered as a sub server. Instead, the network computer acting as the former subserver The computer terminal is processed to function as a sub server subordinate to a newly registered sub server.

In the figure, the setting areas A1 to An are virtual area limits arbitrarily determined by the distributed processing management program 50 of the content server 10, and each setting area is classified by region and by Internet service provider (ISP). For example, it is possible to classify variously such as by line service such as leased line or ADSL, by member profile information (ie, age, education, service usage history, etc. of members).

2 is a diagram schematically showing an example of distributed processing for a client network terminal on a communication network according to a preferred embodiment of the present invention.

As shown in Fig. 2, the content server 10 allows a maximum of 255 network computer terminals per unit server to be registered as a sub-stage in the first stage, and each network computer registered as the sub-stage in the first stage. The network computer terminals, which are slower in line speed than the terminal, are cascaded up to 5 units per unit sub-server in one stage, for example, so that a total of 1,275 network computer terminals can function as lower stage sub-servers in the second stage.

In addition, the content server 10 is connected to the other network computer terminal is slower than the network computer terminal that is applied as the lower sub-server of the second step, for example, by connecting subordinate sub-servers per unit, such as five units of a total of 6,375 It allows the network computer terminal to function as a subordinate sub-server in the third stage, while per subordinate sub-server per unit for other network computer terminals having a slower line speed than the network computer terminal applied as the subordinate sub-server in the third stage. For example, a total of 31,875 network computer terminals can function as four subordinate sub-servers by cascading five units.

In addition, in the content server 10, the remaining network computer terminals other than the network computer terminals that are applied as the sub-servers of the first to fourth stages are connected to the lower sub-servers of the four-stage subordinate servers, for example, by five units, for a total of 159,375 networks. Allows a computer terminal to provide web content services.

In other words, as shown in FIG. 2, the content server 10 provides 25 upper IP addresses, for example, to a maximum of 255 network computer terminals COMA1 to COMAn having the fastest line speed for each setting area A1 to An. For example, five lower IP addresses are allocated, and the web content service can be carried out through the information data received from the content server 10 as a sub-server in the first stage, and the information data of the web content service is transferred to the lower network. Transfer to computer terminals (COMB1 to COMBn) is possible.

In addition, in the network computer terminals COMB1 to COMBn registered as the lower sub-servers of the second stage, the upper sub-servers are assigned the 25 upper IP addresses and the five lower IP addresses, for example, received through the sub-server of the first stage. The server connection is performed in accordance with the connection state of the subordinate subordinate server and the lower subordinate server, and the web content service can be performed through the information data received from the upper subordinate server of the first step. The data is transmitted to the lower network computer terminals COMC1 to COMCn.

In addition, in the network computer terminals COMC1 to COMCn registered as the lower sub-servers in the third step, for example, 25 upper IP addresses and five lower IP addresses are assigned to the server through the lower sub-servers in the second step. It is possible to variably perform the web content service through the information data received from the lower sub-server in step 2 and to transmit the information data of the web content service to the lower network computer terminals COMD1 to COMDn. Done.

Subsequently, in the network computer terminals COMD1 to COMDn registered as the lower sub-servers in the fourth step, the 25 upper IP addresses and the five lower IP addresses are assigned through the lower sub-servers in the third step. It is possible to perform the connection variably, and to proceed with the web content service through the information data received from the lower sub-server in step 3, and to transmit the information data of the web content service to the lower network computer terminals COME1 to COMEn. Will be sent.

As a result, the web content services COME1 to COMEn in the last stage can proceed with the web content service based on the information data received from the lower sub-server in step 4.

Here, the client network computer terminals COMA1 to COMAn registered as the upper level subordinate servers of step 1, and the network computer terminals COMB1 to COMBn registered as the lower subordinate servers of steps 2 to 4 (COMC1 to COMCn) (COMD1). ~ COMDn), and the client network computer terminals COME1 to COMEn corresponding to the final stage in five steps, respectively, are assigned to the upper or lower network computer terminals through the assigned 25 upper IP addresses and 5 lower IP addresses, respectively. It checks whether the connection is disconnected, and attempts to reconnect with a network computer terminal of another upper IP address or lower IP address according to the disconnection state so that normal web content service can be performed.

That is, in the client network computer terminal registered as the sub server from the contents server 10, a maximum of 255, for example, is registered for one hardware server as an upper sub server, and for example, at each step from the 255 upper sub servers. If five network computer terminals are registered as subordinate servers and end terminals, a total of 199,155 client computers (ie, 255 + 1275 + 6375 + 31875 + 159,375) can be accommodated for one unit hardware server. do.

Next, the operation of the present invention made as described above will be described in detail with reference to the flowchart of FIG. 3.

First, when a plurality of client network computer terminals respectively existing in the plurality of setting areas A1 to An attempt to connect to the website 30 of the content server 10 via the Internet communication network (step S10), The content server 10 checks the line speeds of a plurality of network computer terminals attempting to connect to the website 30 by operating the distributed processing management program 50 (step S11).

In this state, the content server 10 determines whether or not the line speed checked for the network computer terminal is good under the operation of the distributed processing management program 50 (step S12), and sets each of the setting areas A1 to An. For example, 25 upper IP addresses and 5 lower IP addresses, for example, are assigned to the network computer terminals COMA1 to COMAn having the fastest line speeds, and registered as upper level sub-servers in each stage (step S13).

On the other hand, for a network computer terminal whose line speed checked by the distributed processing management program 50 is slower than the network computer terminals COMA1 to COMAn registered as the upper sub server, for example, it is dependent on the upper sub server in the first step. 5 upper IP addresses and 5 lower IP addresses, for example, are allocated and connected, respectively, and are registered as lower sub servers in two stages (step S14).

Here, the content server 10 checks the line speed of the network computer terminal registered as the lower sub-server in step 2 (step S15), while the network computer terminal on which the line speed is checked is the final terminal in step 5. It is judged whether or not it is a terminal according to the method (step S16).

As a result of the determination in step S16, if it is determined that the network computer terminal on which the line speed is checked is not the terminal according to the last stage of step 5, the process from step S12 to step S15 is repeated, thereby performing steps 2 to 4 As the subordinate subservers are registered, the subordinate subservers are allocated as subordinate servers connected to subordinate subordinate servers of 25 subordinate IP addresses, for example, 25 subordinate IP addresses and 5 subordinate IP addresses.

On the other hand, in the network computer terminals COMA1 to COMAn registered as the upper sub server of step 1 in step S13, the connection IP address information is registered by the assigned 25 upper IP addresses and 5 lower IP addresses, for example. The information on the registered connection IP address is transmitted to the content server 10 (step S17).

If the content server 10 determines that the network computer terminal of the target line speed is checked in step 5 according to the determination result of step S16, the sub-servers of steps 2 to 4 are respectively determined. In step S17, the information on the connection IP address is registered in the network computer terminals COMB1 to COMBn (COMC1 to COMCn) (COMD1 to COMDn) and the network computer terminals COME1 to COMEn registered as the final terminal in step 5. In addition to registering the information of the connection IP address is transmitted to the content server (10).

Next, the network computer terminals (COME1 to COMEn) registered as the lower sub-servers of the fourth stage and the final terminal of the fifth stage, distributedly cascaded from the upper sub-server of the first stage and the sub-server of the first stage. In step S18, predetermined web content services such as e-commerce, network games, internet broadcasting, database searching, and the like are performed through the information data provided from the content server 10 (step S18).

On the other hand, the network computer terminal of each of the lower sub-servers and the end terminal determines whether the upper sub-server or the lower sub-server registered as the upper IP disconnects the connection based on the pre-assigned upper IP and lower IP addresses. (Step S19).

As a result of the determination, if it is determined that the upper sub server or the lower sub server is disconnected, the lower sub server or the last terminal which is connected to the lower sub server or the lower sub server which is disconnected from the upper sub server or the lower terminal is pre-assigned the upper IP The operation of reconnecting to another upper sub server or lower sub server is performed by the address and the lower IP address (step S20).

When the reconnection of the server as described above is completed, the lower sub-server or the end terminal that has been reconnected proceeds to re-register the information of the connection IP address by the pre-allocated upper IP address and lower IP address. The information of the re-registered connection IP address is transmitted to the content server 10 side (step S21).

It is a matter of course that the present invention having the above-described embodiments can be variously modified and implemented without departing from the spirit and scope of the embodiments.

As described above, according to the present invention, the sub server is configured by checking the line speed of the client network computer terminal connected to the hardware server providing the predetermined web content service, and configuring the sub server in the order of the highest line rates. By distributing the information of the web content service through it, it is possible to fully accommodate a large number of client computer terminals even with a few hardware servers.
