Embodiment Construction

[0023] Such as figure 1 As shown, the redirection load distribution model provided by the present invention includes the following components,

[0024] (1) Client 1, used to provide spatial data service request operations to clients;

[0025] The client part is mainly composed of the client computer equipped with the client software of the spatial data application system; the client is connected to the load balancer and the spatial data server through the network (usually using the Internet). The client part belongs to the existing part of the prior art. In a cyberspace data application system, the number of clients is often huge and uncertain, and the user only needs to install client software on a personal computer, which means creating an accessible client. Therefore, unless the space data application system with high security requirements (such as military use), the client 1 and other parts adopt the internal LAN connection, and the Internet connection is the most conven...

Abstract

The invention relates to a dynamic load balancing method based on spatial geographical locations. The method comprises the following steps: a redirection load distribution model is adopted and a load indicator is selected; a dynamic packet-scheduling algorithm based on spatial geographical locations is adopted to realize the load balance of a spatial data server cluster. The method has the advantages: the dynamic load balancing method based on spatial geographical locations is adopted to optimize the load balancing performance of spatial data servers; the redirection load distribution model is adopted, which eliminated the bottleneck of a load balancing unit; and the dynamic packet-scheduling algorithm based on spatial geographical locations is adopted, thereby improving the Cache utilizing rate of the spatial data servers. The implementation of the dynamic load balancing method provides a solid network basis for the promotion and application of global geographic information and brings great convenience to applying geographic information in every aspect of human life.

Description

technical field [0001] The invention relates to the technical field of geographic information, in particular to a dynamic load balancing method based on spatial geographic location. Background technique [0002] In a large-scale spatial data network service system, in order to improve the bandwidth and response speed of network services, server cluster technology is usually used to centralize management of multiple spatial data servers, and the corresponding load balancing technology is used to achieve system load balancing. Designing an effective load balancing method to ensure load balancing among spatial data servers and improve the Cache hit rate of a single spatial data server is the key to improving the load capacity of server clusters. [0003] A lot of research has been done on load balancing scheduling algorithms in server clusters at home and abroad. In the open source Linux virtual server cluster, a variety of load balancing scheduling algorithms are implemented....
