Problems solved by technology

[0004] However, during the operation and maintenance of clock synchronization through the Network Time Protocol (NTP), the following problems are encountered: (1) The time of the virtual machine is not capable of maintaining the frequency of its own crystal oscillator, which may easily lead to deviation. The network time protocol ntp is constantly revised. If the synchronization to the server is too frequent, the server will bear greater pressure. If the synchronization frequency is too low, the time of the virtual machine will be deviated.
(2) When the pressure on the server is high, it may not be able to respond to new requests, which may lead to deviations in the time of the virtual machine
(3) The traditional clock synchronization device usually focuses on the configuration of the client. Facing the large-scale cloud computing environment, it lacks the management and operation and maintenance of the server, and the operation and maintenance efficiency is low.

Abstract

The present invention provides a clock synchronization method and system. The system consists of a core clock server, a plurality of regional clock servers and a plurality of cloud virtual machines. The method includes: performing the first synchronization on the regional clock servers by the core clock server. One clock is synchronized, and the synchronization strategy of the first clock synchronization is adjusted according to the feedback information of the regional clock server; the second clock synchronization is performed by the regional clock server on the cloud virtual machines in the corresponding region, and the The feedback information of the cloud virtual machine in the area adjusts the synchronization policy of the second clock synchronization. By using the above method, the stability of clock synchronization of large-scale cloud virtual machines in a cloud environment can be improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a clock synchronization method and system. Background technique [0002] This section is intended to provide a background or context for the embodiments of the invention. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] At present, cloud computing has become the mainstream technology in the industry. In a virtualized environment, the number of virtual machines at a single site can reach 100,000 orders of magnitude. For virtual machines in large-scale cloud environments, ensuring the clock accuracy of virtual machines is a crucial issue. [0004] However, the following problems are encountered in the operation and maintenance of clock synchronization through the Network Time Protocol (NTP): (1) The virtual machine time is prone to deviation due to the insufficient frequency retention capability of its own crystal ...
