A system for realizing cluster device communication

Abstract

The invention relates to the cluster communication technology field and discloses a system capable of realizing cluster equipment communication. The system comprises multiple communication entities participating in cluster communication and multiple logic channel realization CC modules distributed in all the communication entities, wherein logic channels are simultaneously connected with the multiple communication entities and provide communication quality service, the logic channels are bus type software communication channels and provide data communication among the entities through a unified set of software interfaces to an upper-level application, different logic channels are distinguished from each other through channel names or channel descriptors, and the CC modules comprise channel communication frameworks and channel communication carrier drivers. Through the system, data disorder and crosstalk among different channels can be avoided, and complete data transmission and data transmission efficiency improvement are guaranteed.

Description

technical field [0001] The invention relates to the technical field of group communication, and discloses a system for realizing communication of group devices. Background technique [0002] Process is one of the important concepts in the field of computer software. It has an important difference from the static "program" concept. Because "program" cannot describe the dynamic, concurrency, independence, and asynchronous characteristics of program execution, the industry has introduced the concept of process. : A running process of the program on the data. Process communication, inter-process communication (IPC), any management task can be completed by several processes running concurrently with each other, and they often keep in touch with each other in order to complete the specified tasks in a coordinated manner. These connections are the information exchanged between processes. The amount of information can be more or less, as many as hundreds of data, as little as a sta...

Problems solved by technology

[0005] Most of the communication between existing equipment cluster units adopts the TCP / IP protocol family or some private layer-2 protocols through the interfaces scattered in different upper-layer application modules, and there is basically no independent communication framework module to isolate the upper-layer application and the actual communication protocol or carrier , once the communication protocol and carrier change, all upper-layer application modules associated with cluster device communication need to be modified synchronously, which reduces the maintainability of upper-layer applications; additional QOS or other public services cannot be provided; the timeliness of communication based on the connection method is not High and difficult to achieve hot backup; client-server mode can only initiate communication requirements in one direction; upper-layer application modules need to build their own sessions, which increases the development burden of upper-layer applications and software complexity and other disadvantages
