For the clear description, the following description illustrates that the service server 151 comprises message module 1511, storage module 1512, authentication module 1513 and data generating module 1514.


The message module 1511 is used for sending service server data, receiving client device connection notification, and establishing connection between the client devices. The storage module 1512 saves the service server data, client device connection notification or the other data. The authentication module 1513 checks the client device connection notification between the client device which requests the connection is correct or not. The data generating module 1514 generates the service server data. The service server data may comprise the combinations of server ID, IP address, port, service type, geographical location, load, computational capability or network speed. Specifically, the time to trigger the data generating module 1514 to generate the service server data, comprising the certain period, certain time of a day or the renewal/changing of the service server.


Please see FIG. 2. FIG. 2 illustrates a flow chart of dynamic distribution service server of a preferable embodiment of the present invention. Please further refer to FIG. 1 and FIG. 2 simultaneously as follows. First of all, the step S01 sends a plurality of service server data which is related to a plurality of service servers 13 to index server 11. For example, when the data generating module 1514 of the service server 151 generates the service server data, the message module 1511 of the service server 151 instantly sends the service server data to the index server 11 and saves the service server data in the storage module 112 of the index server 11. The foregoing description should be realized as the service servers 152-156 are allowed to send the service server data per se to the index server 11. On the other hand, the data generating modules of the service servers 151-156 are allowed to generate the renewed service server data thereinafter. The renewal time comprises but not limited to certain period, certain time of a day or the renewal/changing of the service server. If there is any service server has been renewed and generates a new service server data, the renewed service server data is allowed to be sent to the index server 11.


In step S02, the client device data of the plurality of the client devices 12 are saved into the index server 11. The user of index server 11 may set/select the filter condition of the system distribution rule or insert the client device data based on the user interface provided by configuration module 114. In an embodiment of the present invention, the inserted client device data may be identification number, geographical location or etc. of each client device. On the other hand, the filter condition of the system distribution rule may be set to select a service server which performs the best computational capability. The other capable filter conditions of the system distribution rule have been described above, the repeated description is omitted herein.


In step S03, at least one client device of the plurality of client devices 12 sends a connection service request to index server 11. For instance, when the first client device 1212 of the plurality of client devices 12 needs to establish a connection with a service server therefore to acquire a service, the message module 1211 of the first client device 121 will send a connection service request to index server 11. The connection service request comprises but not limited to identification number and service needs of the client device. The service needs contain the requirements for index server 11 to provide the service server data which matches the conditions of geographical location, greater computational capability or network speed, but the present invention is not limited thereto.


In step S04, the connection service request triggers that the at least one service server data of the plurality of service server data of the index server 11 will be sent to the aforementioned at least one client device. When the message module 111 of the index server 11 receives the connection service request which is sent from the first client device 121, the authentication module 113 of the index server 11 recognize first client device 121 is an authorized client device or not based on the sent connection service request. For instance, the identification number of the client device in the connection service request is used for checking the client device data saved in the storage module 112. The client device is only allowed to send the service server data to the first client device 121 after the client device has been checked and being authorized. In the present step, the authentication module 113 of the index server 11 may execute calculation based on the system distribution rule of storage module 112, determining to send service server data which is from different groups to the different client devices 121-123. Moreover, the specific service server data which is selected as a recommended service server data and sending to certain client device based on the system distribution rule is also allowed.


For example, the first client device 121 of paying user A (Client A) is located in Taipei City and the requirement of the computational capability is high; The second client device 122 of paying user B (Client B) is located in Taichung City and the requirement of computational capability is low; the third client device 123 of free user C (Client C) is located in Taipei City and the requirement of computational capability is low; The service servers 151 and 152 are the service servers which only allow to serve the paying user (Client) from Taipei City. The service servers 154, 155 and 156 are the service servers which only allow serving the paying user (Client) from Taichung City. The service servers 153 is a service server which serves the paying/free users (Clients) form Taipei City. In addition, the computational capability of service servers 152, 153, 155 and 156 are low or limited, and the computational capability of service servers 151 and 154 performs well. In the first distribution embodiment of the present invention, the system distribution rule regards the geographical location and payment status as the distribution criteria. The message module 111 of the index server 11 will send the service server data of the service servers 131 of the first group to the first client device 121 (the distribution between the paid server and the paying user (client) located in Taipei City). The message module 111 of the index server 11 will send the service server data of the service servers 132 of the second group to the second client device 122 (the distribution between the paid server and the paying user (client) located in Taichung City), and the message module 111 of the index server 11 will send the service server data of the service servers 153 to the third client device 123 (the distribution between the paid/free server and the free user (client) located in Taipei City).


In the second distribution embodiment of the present application, the distribution criteria of the system distribution rule are geographical location and computational capability. Therefore, the message module 111 of index server 11 sends the service server data of service servers 151 to the first client device 121 (the distribution between the server having high computational capability and the user (client) who requests for high computational capability in Taipei City). The message module 111 of index server 11 sends the service server data of service servers 155 and 156 to the second client device 122 (the distribution between the server having low computational capability and the user (client) who requests low computational capability in Taichung City), and the message module 111 of index server 11 sends the service server data of service servers 152 and 153 to the third client device 123 (the distribution between the server having low computational capability and the user (client) who requests low computational capability in Taipei City).


As the foregoing description, the system distribution rule may select the data with optimized condition of the data of certain service server as the recommended service server data and provide the recommended service server data to the specific client devices. For example, in the third distribution embodiment, the message module 111 of index server 11 sends the service server data of service servers 151 to the first client device 121 (the distribution between the paid server having high computational capability and the paying user (client) who requests high computational capability in Taipei City). The message module 111 of index server 11 sends the service server data of one chosen server from a group consisting of service servers 155 and 156 (the service server 155 is selected here) to the second client device 122 (the distribution between the paid server having low computational capability and the paying user (client) who requests low computational capability in Taichung City), and the message module 111 of index server 11 sends the service server data of service servers 153 to the third client device 123 (the distribution between the paid/free server having low computational capability and the free user (client) who requests low computational capability in Taipei City). When the message module 111 of index server 11 sends the recommended service server data, it also sends the client device connection notification notify the certain service server that the certain client device request for establishing connection. As the described third distribution embodiment, the message module 111 of index server 11 sends the client device connection notification which is used for notifying the service servers 151 that the first client device 121 will request for establishing connection. The message module 111 of index server 11 sends the client device connection notification which is used for notifying the service servers 155 that a client device 122 of the second group will request for establishing connection. The message module 111 of index server 11 sends the client device connection notification which is used for notifying the service servers 153 that the third client device 123 will request for establishing connection.


Furthermore, the step S04 further comprises that if the index server 11 receives the renewal of service server data, the authentication module 113 is allowed determining whether to send different service server data to different client devices 121-123 again. For example, the service servers 151-156 would renew the service server data per se because of the offline of server, the increased number of the connected client devices, network speed getting slower or the other reasons. Therefore, the content of the re-sent service server data is also changed.


In step S05, the client device establishes the connection with the service server corresponding to the service server data. In current step S05, the message module of every client device of the plurality of client devices 12 receives a service server group data or at least one service server data which is sent from the index server 11, and saves the service server group data or at least one service server data in the storage module. Therefore, the authentication module may execute the calculation based on the client distribution rule, which is saved in the storage module, therefore to determine establishing the connection with one of the service servers of the received service server data. When the plurality of the client devices 12 receives the re-sent service server data, the plurality of the client devices 12 may determine whether to establish a connection with one of the service servers of the re-sent service server data. In this step, the user of the client device can further use the user interface which is provided by the configuration module to set the filter conditions of client distribution rule. Moreover, the user interface may display the service server data received by the client device and the user is allowed to choose the at least one service servers from the service server data, and establishing the connection.


For instance, as the first distribution embodiment, the index server 11 sends the service server data of the first group of service servers 131 to the first client device 121. The index server 11 sends the service server data of the second group of service servers 132 to the second client device 122, and sends the service server data of the third group of service servers 153 to the third client device 123. That is, in the first connection embodiment, the user interface provided by configuration module 1214 of the first client device 121 displays the service server data which is received by the first client device 121 form the first group of the service servers 131. Thereafter, the user of the first client device 121 selects the one of the service servers of the first group of service servers 131 and establishes the connection. In a second connection embodiment, the authentication module 1213 of the first client device 121 may execute the calculation based on the client distribution rule of the storage module 1212, determining whether to establish the connection with the service server 151 (After the first client device 121 receives the service server data of the first group of service servers 131, the priority performed by the client distribution rule preferably select the service server which performs greater computational capability). Nevertheless, the user of each client device is still able to select the preferred service server and establishes the connection based on the user interface per se. The client distribution rule can also be defined by the user, then the connection between the service server would be automatically established based on the self-defined client distribution rule.


In the other embodiment of the present invention, the service server 151 located in Taipei City is a video service server which has the best computational capability. The service server 152 located in Taichung City is a video service server which has the best computational capability. The service server 154 is a video service server located in Taipei City. The service servers 155 is an audio service server located in Taipei City. The service server 156 is a text service server located in Taipei City. When the first client device 121 sends a connection service request to the index server 11, the index server 11 may follow the instant system distribution rule and divides the service servers 154, 155, 156 into second service server group 132. The service server data of the second service server group 132 will be provided to first client device 121 because the second service server group 132 comprises the servers which provide video, audio, and text services, which satisfy the most service needs. On the other hand, the second client device 122 sends a connection service request to the index server 11, and the index server 11 may follow the noted service needs of the connection service request (the user notes that the video service, a service server having the best computational capability, and the location of the user may be at Taipei or Taichung City). Thus, the index server 11 further follows the system distribution rule and divides the service servers 151, 152 into the first service server group 131. The service server data of the first service server group 131 will be sent to the second client device 122, directly satisfying the needs of the user of the second client device 122.
