Problems solved by technology

If all service nodes provide the same service, each node must store the same data. For massive geographic information data, each service node stores the same data. On the one hand, it increases the storage burden of each service nod

Embodiment Construction

[0046] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] refer to figure 2 , which shows a schematic diagram of the structural relationship between a distributed hierarchical cluster system for geographic information services and a client terminal in Embodiment 1 of the present invention. The distributed hierarchical cluster system for geographic information services in Embodiment 1 includes N root load balancers, where N is set by those skilled in the art according to actual conditions and is at least 1. The root load balancer 1 has a first-level balancer sub-node, and the balancer sub-node includes two sub-load balancers. Of course, it may only include one sub-load balancer or include more than two sub-load balancers. Among them, the sub-load balancer 1 is the middle child no...

Abstract

The invention provides distributed level cluster method and system of geographic information service, wherein the cluster system comprises a plurality of load equalizers, a plurality of secondary load equalizers and a plurality of service nodes. Each load equalizer is provided with at least one stage equalizer secondary node; the equalizer secondary node comprises at least one secondary load equalizer; and the secondary load equalizer of the equalizer secondary node is an equalizer middle secondary node or an equalizer leaf node belonging to a root load equalizer. When the secondary load equalizer is the equalizer middle secondary node, the secondary load equalizer has a next stage equalizer secondary node; when the secondary load equalizer is the equalizer leaf node, the secondary load equalizer has a leaf service node secondary node, and the leaf service node secondary node comprises at least one service node. The invention can reduce the storage burden of the cluster system, solve the problem of low reliability of the cluster system, which is caused by the storage burden, realize cluster redundancy and increase the efficiency and the reliability of the whole cluster system and does not need to increase additional costs.

Description

technical field [0001] The invention relates to the communication field, in particular to a distributed hierarchical clustering method and system for geographic information services. Background technique [0002] Cluster technology is a computer system that connects multiple servers together to form a highly transparent large-scale server group, and provides services for clients as a whole. The client can share all the resources on the network, such as data or application software, etc. At the same time, the user of the client does not care which server the application service runs on, but only cares whether the application service can work continuously. When a server in the cluster system fails, its standby server will immediately take over the application services of the failed server and continue to provide services for the client users. From the perspective of the client, all the servers in the cluster are a system, like a large computer system, on which the application...
