The registration information is typically in the form of: the serial number generating device registers the node/serial number generating device IP address/number interval; the specific process of registration is as follows: the registration apparatus 20 first searches for a "registration node of the serial number generation apparatus" under the root node, and then creates a new node under the registration node of the serial number generation apparatus, where the new node is used to store the registration information of the serial number generation apparatus (as shown in fig. 2); if the "serial number generation apparatus registration node" does not exist, the registration apparatus 20 first creates a "serial number generation apparatus node" under the root node, and then creates a new node according to the registration information under the serial number generation apparatus registration node.

In addition, the registration apparatus 20 stores all node information under all "serial number generation apparatus registration nodes", which is typically stored in the form of a service registration list.

The sequence number of the previous request message usually refers to the sequence number of the request signal that is one time before the request signal and the request for generating the sequence number are received, the sequence number of the previous request message is usually stored in a database, and the sequence number generating device 40 can periodically obtain the sequence number from the database.
The serial number generation system for the request information comprises a configuration device 10, a registration device 20, an information acquisition device 30 and at least one serial number generation device 40; firstly, each serial number generation device 40 acquires corresponding configuration information from the configuration device 10, completes information configuration according to the configuration information, and sends a registration request to the registration device 20; the registration device 20 registers each serial number generation device according to the configuration information to generate corresponding registration information; the registration information comprises an address of the sequence number generation device and a number interval corresponding to the address; the information acquisition device 30 acquires the request information and extracts the number of the request information; acquiring registration information, determining the address of a serial number generation device according to the number interval when the number is in the number interval, and sending request information and a serial number generation request to the serial number generation device corresponding to the address; the sequence number generating means 40 is used for obtaining the sequence number of the request information according to the sequence number generation request and the sequence number of the previous request information. The system comprises a plurality of serial number generating devices 40, each serial number generating device 40 can generate serial numbers for the request information in a certain number interval, and can divide the various request information in different number intervals into different serial number generating devices for serial number generation, so that the time delay of information processing is reduced, and the information processing speed is greatly improved; in addition, the registration information is obtained by registering according to the configuration information, when the configuration information is changed, the registration information can be correspondingly changed, the request information of the number interval which can be processed by the corresponding sequence number generation device can be changed, and the dynamic expansion is very convenient.
In one embodiment, as shown in fig. 3, each sequence number generating device 40 includes a master sequence number generating device 42 and a slave sequence number generating device 44, wherein the master sequence number generating device 42 and the slave sequence number generating device 44 have the same structure; when the master serial number generating device 42 fails, the slave serial number generating device 44 is configured to obtain the same configuration information as the master serial number generating device 42 from the configuration device 10, complete information configuration of the slave serial number generating device according to the configuration information, and send a registration request to the registration device 20; the registration means 20 is configured to register the slave sequence number generation means 44 based on the configuration information, generate registration information of the slave sequence number generation means 44, and delete the registration information of the master sequence number generation means 42.

In general, the registration apparatus 20 deletes the information node of the master serial number generation apparatus 42 and adds the information node of the slave serial number generation apparatus 44 to the "serial number generation apparatus registration node". The method of the master sequence number generating device 42 and the slave sequence number generating device 44 can ensure that the standby sequence number generating device is started quickly when one sequence number generating device fails, and avoids the problem that the sequence number generating device fails to generate the sequence number of the request information.
In one embodiment, as shown in fig. 3, the system further includes a database 50, and the database 50 is used for storing snapshot information of the sequence number of the history request information.

A snapshot refers to a fully available copy of a given data set that includes an image of the corresponding data at some point in time (the point in time at which the copy began). The snapshot may be a copy of the data it represents or may be a replica of the data. The snapshot mainly has the function of online data backup and recovery. When the storage device has application failure or file damage, the data can be quickly recovered, and the data can be recovered to the state of an available time point. The snapshot has another function of providing another data access channel for the storage user, so that when the original data is subjected to online application processing, the user can access the snapshot data and can also utilize the snapshot to perform work such as testing. All storage systems, whether high, medium, and low, are applied to online systems, and then snapshot becomes an indispensable function. By adopting the snapshot sequence number capable of rapidly and accurately storing the historical request information, the sequence number of the request information can be effectively ensured to be generated according to the sequence of the request information without errors.

The atomicity means that when a certain calculator is modified by a plurality of threads simultaneously, the numerical value of the calculator is guaranteed to be correct after each thread is modified, and the concurrent control of multiple threads can be generally realized by adopting a CAS optimistic lock. The sequence number snapshot generating module 426 generates a snapshot of the historical request information at a sequence number timing (e.g., 10 seconds) and stores the snapshot in the database. And a timing storage mode is adopted, so that the interaction times with the database are reduced.
