Problems solved by technology

[0005] The traditional procedure call is compiled locally by the developer and can only run on the local machine. This structure can no longer meet the actual needs of distributed system applications.
Traditional procedure calls have no way to make full use of the system resources of other machine nodes on the network, and there is no way to improve the degree of code sharing among entities, so that the machine resources of the distributed system are not fully utilized

Embodiment Construction

[0024] The present invention will be further explained below in conjunction with the accompanying drawings.

[0025] Such as image 3 As shown, a multi-node data interaction implementation method, arrange data service modules on each machine node, the data service module on any node is used to realize the data interaction between the node's own processes, the data on different nodes The service module implements data interaction between different node processes. The data service module implements data interaction between processes based on the remote procedure call protocol, and the bottom layer of the remote procedure call protocol is realized through the Qt meta-object system. The data interaction between nodes includes data access and operation, file transfer and node data backup; the remote call process is based on the Qt meta-object system to realize service search, parameter input and result return. When the process interacts with the node process or other node process...

Abstract

The invention discloses a multi-node data interaction achieving method. A data service module is arranged on each node. The data service module on any node is used for achieving data interaction between own progresses of the node. The data service modules on the different nodes are used for achieving data interaction between progresses of the different nodes. The data service modules achieve data interaction between the progresses through a remote procedure call protocol, and a bottom layer of the remote procedure call protocol is achieved through a Qt element object system. By using the method, service management on the multiple progresses distributed on the same node and the progresses on the different nodes can be finished smoothly, and meanwhile the complexity of program implementation of a traditional data interaction method can also be reduced.

Description

technical field [0001] The invention relates to business processing between multiple nodes, in particular to a method for realizing node data interaction. Background technique [0002] With the rapid development of computers and networks, distributed processing systems are widely used. In order to access the data and resources of other machine nodes, a node in a distributed system generally performs data interaction or business processing through a custom message format. The communication efficiency of this method is very low and the maintenance and development workload is relatively large. When adding or modifying a certain function, it may be necessary to add a new message format or modify the existing message format, so the coupling degree between modules in the system is relatively high, and the independence is relatively poor. If machine nodes access the data and resources of other machine nodes through procedure calls, the complexity of process implementation can be ...
