Embodiment Construction

[0050] Take the single-network client sending a registration message to the single-network server as an example. After the state machine in the channel of the single-network client switches to the state of sending the registration message, it will call the function of sending the registration message in the channel, and perform message pre-processing in this function. Processing, add a header message to the registration message, put the message into the sending queue after preprocessing the message, and the sending queue sends data by calling the asynchronous sending function of the collection asynchronous communication module. After the data is sent successfully, the state machine of the single network client calls its own The state transition function converts the state to the state of waiting for the registration receipt, and calls the receiving registration message receipt function in the channel to receive the message. The single network client channel sends the registratio...

Abstract

The present invention relates to a highly reliable data transmission method based on redundant network asynchronous communication, which adopts dual-network redundant network to improve transmission reliability, and mainly involves four parts: the first part, the channel layer, is mainly responsible for the connection between the client and the server and The transmission of messages; the second part controls the state machine of the channel layer, which is used to cope with changing network states, controls the channel to process different data in different states, and simplifies the logical structure of the channel layer; the third part, the collection layer, is used for data The sending and receiving of messages uses asynchronous functions for message transmission to improve the efficiency of message transmission; the fourth part of the message sending queue and receiving queue is used to adapt to the asynchronous sending and receiving of messages and avoid blocking when receiving or sending messages. Through the coordination of these four parts, the data transmission has higher efficiency and reliability.

Description

technical field [0001] The invention belongs to the field of software and relates to a redundant network transmission method based on asynchronous transmission. Background technique [0002] With the development of Internet technology and the maturity of distributed technology, the application of distributed systems has been widely popularized, and the priority of distributed systems is to solve large-scale information transmission and real-time and reliability of messages. For example, we have a command The center needs to command a batch of transport convoys. The convoys are widely distributed geographically. However, we require high real-time performance when commanding the convoys, which requires high efficiency in message transmission. In another situation, such as troops commanding operations, the message sent by the command center to each army must be accurate, but the message may be disturbed during the sending process and cause errors in the transmitted message. In ...
