Abstract

The invention provides a continuous sequence number generation system and a continuous sequence number generation method. The system comprises N servers, wherein the N servers are mutually connected, each server comprises a sequence number maintenance file and a reception buffer memory file, the N is a positive integer, the sequence number maintenance file is used for storing present largest sequence numbers, the reception buffer memory file is used for receiving synchronization signals sent by other servers, the synchronization signals comprise present largest sequence numbers of other servers, after a sequence number distribution request is received by the Mth server, the M is greater than zero and is smaller than or equal to the N, the Mth server is used for acquiring the present largest sequence number of the Mth server; a new sequence number is generated according to the present largest sequence numbers, response feedback is further distributed according to the sequence number, the synchronization signals are sent to other servers by the Mth server, and the synchronization signals have the new sequence number. The continuous sequence number generation system realizes high-efficiency and reliable generation of continuous sequence numbers in a distributed environment and improves availability.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a system and method for generating continuous sequence numbers. Background technique [0002] With the rapid development of the Internet, serial number generators are used in more and more application scenarios to generate serial numbers, for example, the order number of payment products, the waybill number of logistics, the account id (Identity, identity identification number) of registered users, etc. . At present, the main method for generating serial numbers is to use a single server to generate serial numbers. For example, when a client sends a request for a new serial number to the server, first, the server opens the last generated serial number saved in the local file, and then converts its value After self-increment, store the new serial number back into the file and respond to the client to realize the generation of continuous serial numbers. [0003] The current prob...
