An agent-based distributed system state control method and system

Abstract

The invention provides a distributed system state control method and system based on agencies. Setting is conducted in advance so that agency modules can correspond to single-machine nodes in a distributed system one to one. According to the original state configuration of the agency modules, communication between the intermediate node in the distributed system and the single-machine nodes corresponding to the agency modules, and the communication between the single-machine nodes corresponding to the agency modules and other single-machine nodes are taken over. When state control is conducted, a user interface sends a control instruction to a center control module. The center control module issues the control instruction to the agency module corresponding to the single-machine node to which the control instruction is oriented, and the agency module executes corresponding processing logic on a message according to the control instruction after receiving the control instruction. The method and the system are not limited to a specific application scene and can not affect integrity of the distributed system.

Description

Technical field

[0001] The invention relates to the field of computer application technology, in particular to an agent-based distributed system state control method and system.

Background technique

[0002] In a distributed system, a group of independent computers presents the user as a unified whole, as if it were a system. The system has a variety of common physical and logical resources, which can dynamically allocate tasks, and the scattered physical and logical resources realize information exchange through the computer network.

[0003] figure 1 As a typical distributed system, it consists of a single central node and more than two stand-alone nodes. The central node is responsible for sending control commands and maintaining the cluster state, and the stand-alone nodes are responsible for executing stand-alone logic. Among these nodes, the typical interaction is: the central node sends control commands to the stand-alone node, the stand-alone node sends various...
