Cloud platform clock time service method and system

Abstract

The invention provides a cloud platform clock time service method and system, and the method comprises the steps: calibrating a clock of a main control virtual machine according to a precise clock ofa clock source, obtaining a calibrated main control virtual machine clock, and forming a virtual machine clock card to provide a clock service; according to the clock service port identifier of the first service virtual machine to be subjected to time service, searching a corresponding relationship among the clock service port identifier of the main control virtual machine, the clock service portidentifier of the service virtual machine and a clock time service protocol to obtain a first clock time service protocol between the first service virtual machine and the main control virtual machine; and according to a first clock time service protocol between the first service virtual machine and the main control virtual machine, calibrating a clock of the first service virtual machine according to the calibrated main control virtual machine clock through a special clock network, and forming a virtual clock card to provide an accurate clock service. According to the scheme, the flexibilityof providing clock time service for the virtualization service can be improved, the use efficiency of the clock card is improved, and the cost of accurate time service of the cloud platform is reduced.

Description

technical field [0001] The present invention relates to the field of cloud technology, in particular to a cloud platform clock timing method and system. Background technique [0002] Virtualization technology usually provides clock services for services in the virtual machine by means of a virtualized clock. The virtualized clock often suffers from clock drift, and as the service running time becomes longer, the clock drifts more severely. Most of the cloud platforms based on virtualization technology are based on the network clock protocol (NTP) for clock synchronization, and the timing accuracy is at the millisecond level. And many businesses, such as high-speed railway control, earthquake early warning, intelligent power generation control, industrial measurement, etc., require the use of high-precision clock equipment to provide accurate control capabilities and measurement results. The demand for high-precision clocks by these businesses has brought great difficulties...

AI Technical Summary

Problems solved by technology

However, these solutions are either limited by virtualization technology, so that they can only be applied to a specific platform, or each server needs to use a dedicated clock device, which has the disadvantage of poor sharing, and the cloud platform is slightly larger, and the cost is lower. will be high
