Abstract

This application provides a method and device for global load balancing data synchronization time management, which is applied to the site side. The method includes: parsing the DNS request sent by the local user, and creating a corresponding session hold entry based on the DNS request , and synchronize the session keeping entries to other sites, where this site and the other sites are pre-configured load balancing sites; monitor the aging remaining time of the session keeping entries in this site and other sites; Based on a preset algorithm, dynamically adjust the update checking frequency of the session keeping entries in the local station and other stations according to the remaining aging time of the session keeping entries. Applying the embodiment of the present application, under the premise of ensuring that the session keeping entries do not age out, dynamically adjust the detection frequency of whether the session keeping entries are updated based on the aging remaining time of each site, and correspondingly reduce the session time in each site to the greatest extent. Keep the update frequency of entries.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and device for global load balancing data synchronization time management. Background technique [0002] Global load balancing refers to the realization of coordination among multiple data centers through algorithms, so that users can access the optimal site. Global load balancing is based on DNS (Domain Name System, Domain Name System) redirection, so in order to ensure uninterrupted business access, the method of regularly sending the session maintained entries to other sites is usually used to realize the user's DNS request access for the same server. [0003] When performing data synchronization time management, under the premise of ensuring that the session keeping entries do not age out, each station generally sends the session keeping entries to other stations at a fixed frequency, so that each station updates the session keeping entries. [0004] ...
