Embodiment Construction

[0038] like figure 1 As shown, a dispatch center server is set up on the "above" of all clusters to receive request information from users, and achieve load balancing through the settings of its various mechanisms. The dispatch center server is like a bridge between the user and the cluster. It performs a series of functions such as receiving, dispatching, and distribution, so that the influence of other unnecessary factors is ignored between the user and the cluster. It looks like it is only connected with the dispatch center server. Same as communicating.

[0039] like figure 2 As shown, the five tables of the dispatching center server negotiate with each other to ensure the efficient operation of load balancing. The contents of each storage are as follows:

[0040] Resource distribution table: stores the collection of request information that each cluster can process;

[0041] Load table: stores the collection of request information being processed by each cluster;

Abstract

The invention discloses a cluster self-feedback type load balancing scheduling system and method. The method disclosed by the invention comprises the following steps that: a scheduling central server efficiently calls a cluster response service by utilizing self five tables; Master servers in various clusters notify the scheduling central server to update various cluster states in the tables in real time by sending Hello and Update messages; after receiving a user request, the scheduling central server checks a resource distribution table placed therein, determines related processible clusters, and makes the most reasonable processing scheme in combination with an idle table and a distribution historical record table; the Master servers in various clusters periodically send the Hello messages, and notify the scheduling central server of self states; and furthermore, in the event of newly creating or completing a processing task, the Update messages are sent in real time, such that the scheduling central server is notified to modify states of various tables. A feedback mechanism is combined with a reasonable task distribution method, such that the load balancing scheduling method is realized.

Description

technical field [0001] The invention relates to the technical field of load balancing scheduling, in particular to a cluster self-feedback load balancing scheduling system and method. Background technique [0002] With the development of Internet technology, a system composed of a single server can no longer meet the needs of rapidly growing data volume and business processing due to the limitations of the central processing unit and input and output processing speed. The emergence of cluster technology can obtain relatively high benefits in terms of performance, reliability, and flexibility at a lower cost. However, the existing mechanism for the core issue of cluster scheduling is not perfect enough, and there are more or less or less question. For example, it does not consider whether there are clusters that have processed similar requests, does not compare the efficiency of each cluster in processing the same request, and does not realize the dynamic coordination and co...
