Embodiment Construction

[0083] The embodiment of this application provides a method for obtaining absolute time stamps, which can enable servers in a distributed system to conveniently obtain the absolute time stamps of application tasks, and avoid the problems caused by deploying high-precision time synchronization protocols on each server. Configure complex issues. Specifically, the distributed system may include multiple service systems, and the method may be implemented independently by each service system in the distributed system. Each service system may include a server and a GPS (Global Positioning System, Global Positioning System) timing device. Wherein, the server is any server in the service system. The server can be any device that performs application tasks. The GPS timing device is a GPS timing device that provides absolute time stamps for the server in the service system where the server is located. The service system is any system including a server and a GPS authorization device,...

Abstract

The invention discloses a method, a related device and a system for acquiring an absolute timestamp. The method for obtaining the absolute timestamp can be applied to a service system. The service system comprises a server and a GPS time service device, wherein the service system can be a data center, when an application task executed on a server needs to obtain an absolute timestamp of a first moment, the server sends a timestamp request message to a GPS time service device of a service system where the server is located, and the GPS time service device sends a timestamp response message to the server, so the application task can obtain the absolute timestamp of the first moment. By adopting the method, the related device and the system disclosed by the invention, the application task can obtain the absolute timestamp, and a special network card supporting a high-precision time synchronization protocol does not need to be configured for the server, so implementation complexity of the server is reduced.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a method and a distributed system for obtaining an absolute time stamp. Background technique [0002] At present, many applications are distributed applications, and systems that execute distributed applications are called distributed systems. The application programs of the distributed application are often distributed on multiple servers in different data centers of the distributed system, and these servers respectively execute one or more application tasks of the distributed application to realize the functions of the distributed application. The application tasks executed on each server need to be performed according to a certain sequence, otherwise the application tasks may be disordered, resulting in failure to realize the functions of the distributed application. Therefore, when the server executes application tasks, it needs to obtain and record the ...
