detailed description

In order to solve the problem that the state information of the website user is queried in the prior art, the response speed is slow, and the state server is overloaded with excessive load pressure. The present invention synchronizes the user state information on the state server to the search engine server, the search engine server. When the discovered information is included in the searched information, the user's status information is directly queried locally and provided to the user who needs the information.

Referring to FIG. 1A, the communication system in this embodiment mainly includes a status server, and a search engine server connected to the status server, and the search engine server may be multiple. The status server For saving state information of all websites (including instant messaging users), the search engine server is used to search for information related to the keyword from the network according to the keyword provided by the user, and obtain user status information from the status server, and the status server Keep user status information synchronized. When the search engine server finds that the returned webpage contains the user identifier, the user status information is locally queried according to the user identifier and provided to the user requesting the search information.

To ensure information security, the search engine server registers with the status server before obtaining user status information from the status server. The status information of the user includes at least a user identifier and an identifier of whether the user is online.

For state information synchronization, the preferred way is to use incremental synchronization, that is, only transmit user state information that has changed. In the synchronization time, real-time synchronization can be used, that is, the state server actively informs the search engine server when the state of the user changes; or the periodic synchronization can be used, that is, the state server periodically sends the state information to the search engine server, or searches by the state server. The engine server periodically requests the user status information from the status server. When synchronizing the status information between the search engine server and the status server, it is preferable that the status server sends the status information to the search engine in a multicast manner.

The system shown in Figure 1A requires a state server to provide user state information directly to each search engine server, which is primarily suitable for scenarios where the number of search engine servers is small. In the case of a large number of search engine servers, in order to further reduce the load pressure on the state server, a background server (or search engine background server) is added between the search engine server and the state server.

As shown in FIG. 1B, the background server is connected between the state server and the search engine server, and there may be multiple back-end servers, and each back-end server can connect to multiple search engine servers. The background server is used to obtain user status information from the status server and is responsible for providing all user status information to each search engine server. The user state information is synchronized between each backend server and the state server, and each backend server is synchronized with the user state information on each search engine server under its jurisdiction. The synchronization mode can use real-time synchronization or periodic synchronization. For details, refer to the previous description, and details are not described here.

When synchronizing the status information, the preferred method is that the status server sends the user status information to each backend server by using a multicast mode, and each backend server uses the multicast mode to send the user status information to each search engine server.

The structure of a search engine server in this embodiment may be as shown in FIG. 2, including a storage list. a unit, a communication unit, a synchronization unit, a search unit, and a query unit; wherein: the storage unit is configured to store status information of the instant communication user and other related information; the communication unit is configured to connect to other communication devices to receive and send information; The synchronization unit is connected to the storage unit and the communication unit through an interface, and is configured to synchronize user state information in the storage unit with user state information on a state server providing the information through the communication unit; the searching The unit is connected to the communication unit and the storage unit through an interface, and is configured to search for related information including the keyword from the network according to the keyword provided by the user, and the searched information may be cached in the storage unit; The query unit is connected to the storage unit and the search unit through an interface, and is configured to query and obtain user state information from the storage unit when the user identifier is included in the related information searched by the search unit; Relevant information to the user and the user name queried by the query unit Via the communication unit transmits information to the requester. The interface can be an internal communication interface. The synchronization unit, the search unit and the query unit may be set independently of each other, or may be partially or completely integrated.

In order to reduce the amount of data transmission as much as possible in the process of transmitting user state information, in this embodiment, the state server first converts the user ID to compress the number of bytes of the user identifier, and the user identifier is in the background server and the search engine server. Save it in the converted format. Correspondingly, the search engine converts the user ID in the same way as the status server before querying, and then queries the user status information. For example, for a 20-byte user ID, use a hash algorithm (which can also use other algorithms) to convert it to an 8-byte integer data (or an 8-byte number in the database for unique identification). The ID number is used instead, and one bit is used to indicate whether a user is online, such as "0," indicating that the user is not online, "Γ, indicating that the user is online. Therefore, for a registered user of 100 million, the occupied memory is 100M*8+100M*1/8=812.5M, which is sufficient for a 32-bit machine with a 4G memory configuration.

The following mainly describes the system structure shown in FIG. 2 as an example.

Referring to FIG. 3A, the background server obtains user state information from the state server, and the state server actively sends the changed user state information to the background server to keep the synchronization process as follows:

Step 300: The background server sends a registration request message to the status server.

Step 301: The status server authenticates the background server and returns a registration response message to it. The message indicates whether the registration was successful. Step 302: After the registration is successful, the background server sends a user status information request message to the status server.

Step 303: The status server confirms that the background server is a registered user, and transmits all user status information to the background server, where the user identifier in the user status information is compressed in the foregoing manner.

Step 304: The background server saves user status information.

Step 305: The state of the user on the state server changes, and the state server sends the changed user state information to each background server in a multicast manner.

Step 306: The background server updates the locally saved user state information.

Referring to FIG. 3B, the background server obtains the state information of the user from the state server, and the back-end server requests the state server to update the changed user state information to keep the synchronization process:

Steps 310, 311, 312, and 313 are the same as steps 300, 301, 302, and 303 described above, and are not described herein again.

Step 314: The timer expires, and the background server sends a user status information update request to the status server, where the request message includes the time of the last request or update of the user status information.

Step 315: The status server determines, according to the time when the background server last requested or updates the user status information, whether the user status information changes from the time to the current time period, and if there is a change, the user that changes by updating the response message The status information is sent to the background server. Otherwise, a response message not containing the user status information is returned to the background server (the figure indicates that the user status information has changed;).

Step 316: After receiving the update response, the background server updates the locally saved user state information if there is user status information, otherwise, no update process is performed.

In the process flow of FIG. 3B, after receiving the message that one of the background servers requests to update the user state information, the state server may also use the multicast mode to send the changed user state information to all the background servers, and the background server receives the update message. After resetting the timer.

Referring to FIG. 4, the search engine server obtains the user's status information from the background server, and the background server actively sends the changed user status information to the search engine server to maintain the synchronization process as follows:

Step 400: The search engine server sends a registration request message to the background server. Step 401: The background server verifies the search engine server, and returns a registration response message to the server, where the message indicates whether the registration is successful.

Step 402: After the registration is successful, the search engine server sends a user status information request message to the background server.

Step 403: The background server confirms that the search engine server is a registered user, and transmits all user status information to the post search engine server, wherein the user identifier in the user status information is compressed in the foregoing manner.

Step 404: The search engine server saves user status information.

Step 405: After updating the user status information, the background server sends the changed user status information to each search engine server in a multicast manner.

Step 406: The search engine server that receives the update notification updates the locally saved user status information.

Referring to Figure 5, the search engine server searches for information and obtains user status as follows:

Step 500: The user provides a keyword request through the client to search for related information.

Step 501: The search engine server searches for information related to the keyword from the information resource server in the network according to the keyword.

Step 502: The search engine server receives the webpage returned by the information resource server, where the information that needs to be searched and the identifier (ID) of the user that posts the information are included.

Step 503: The search engine server extracts and converts the user identifier from the webpage (the conversion mode is the same as the status server side), and locally queries the user status corresponding to the user identifier.

Step 504: The search engine server embeds the user status identifier into the webpage and returns to the client. For example, when the user is online, it can be represented by a green light in the web page, and when the user is offline, it can be represented by a gray light.

For the system of the structure shown in FIG. 1A, the process of transmitting user state information between the state server and the search engine server and maintaining synchronization is the same as the process of transmitting user state information and maintaining synchronization between the state server and the background server, and no longer Narration.

It can be seen from the above embodiments that the present invention implements the combination of the search engine and the instant communication user state information, and synchronizes the user state information in the instant messaging system state server to the search engine. When the information is queried, the webpage returned by the search engine to the user directly contains the status information of the instant messaging user, thereby improving the response speed of the webpage and reducing the pressure on the instant messaging state server. The spirit and scope of the Ming. Thus, it is intended that the present invention cover the modifications and modifications of the invention
