[0003] Some load balancing frameworks that currently exist only schedule tasks through some simple load balancing algorithms, and do not allocate tasks very accurately according to the real-time load of nodes. At the same time, a single load balancing node needs to complete such as node information collection, load For a series of work such as decision-making and task scheduling, the accumulation of a large amount of information on this node will generate high overhead and delay, making the front-end load scheduling a performance bottleneck of the entire cluster system, thereby reducing the processing efficiency of the system

Embodiment Construction
[0012] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0013] In order to reduce the load of the load balancing node, this scheme adopts the scheme of deploying the load information collection module on each node of the distributed system to monitor the node load data; the load priority queue is always maintained in the load balancing node to reduce the load balancing node response time.
[0014] Such as figure 1 As shown, the dynamic load balancing framework includes distributed system nodes, evaluation index storage nodes, load balancing nodes and their backup nodes, and user access terminals.
[0015] The distributed system node is used to collect the load information of the node, and the information collection module deployed on the node periodically writes the load evaluation index data of the node into the relational database. In order to make the newly saved data in the database as close as possible to the...

The invention relates to a novel load balancing framework and particularly to a dynamic load balancing framework which is applied to a high concurrence access distribution type system. The dynamic load balancing framework comprises distribution type system nodes, evaluation index storage nodes, load balancing nodes and backup nodes thereof and a user access terminal, wherein the load balancing node comprises evaluation index collecting modules, load calculating modules and load list updating modules. According to the dynamic load balancing framework, the evaluation index collecting modules are deployed on every node of the distribution type system, the evaluation index storage nodes are served as information transmission mediums to perform load data transmission with the load balancing nodes, and dispatch of front end user access is performed through a dynamic load balancing algorithm which is based on multiple evaluation indexes. The dynamic load balancing framework has the advantages of being high in stability and rapid in efficiency, solving the efficiency bottleneck of high concurrency data access of the user access terminal and meanwhile avoiding the processing performance problem caused by load overweight of load balancing points.
Description
technical field [0001] The invention relates to a dynamic load balancing framework applied to a distributed system with high concurrent access, and belongs to the technical field of the Internet. Background technique [0002] The load balancing mechanism is based on the distributed system structure, which provides an effective and transparent method for the cluster system to expand the bandwidth of network devices and servers, increase throughput, strengthen network data processing capabilities, improve system flexibility and A technique for usability. Its goal is to reasonably allocate the tasks of the client to each node of the cluster, so as to achieve the load balance of the entire distributed system and ensure the system has efficient data processing capabilities and service quality. [0003] Some load balancing frameworks that currently exist only schedule tasks through some simple load balancing algorithms, and do not allocate tasks very accurately according to the r...
