Abstract

The present invention provides a global server load balance-based data synchronization time management method and apparatus that are applied to the site side. The method comprises the steps of analyzing a domain name system (DNS) request sent by a local user, creating a corresponding session holding entry according to the DNS request, and synchronizing the session holding entry to other sites, wherein the site and the other sites are pre-configured load balance sites; monitoring aging remaining time of the session holding entry in the site and the other sites; and dynamically adjusting, based on a preset algorithm, an updating check frequency of the session holding entry according to the aging remaining time of the session holding entry in the site and the other sites. Through adoption of the global server load balance-based data synchronization time management method and apparatus, while the session holding entry does not age, the check frequency of whether the session holding entry is updated is dynamically adjusted according to the aging remaining time of each site, and correspondingly, the updating frequency of the session holding entry in each site is lowered to the greatest extent.

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] ...
