An event-based real-time simulation method for link conflicts

Abstract

The present invention provides a real-time emulation method of link conflict based on event; broadcasting message content and additional information together to all nodes through interprocess communication method when a network node sends message; after the target receiving node of the message received the message, adding message receiving event, calculating the actual time of accomplishing the receiving according to the message content and additional information, setting up timer to this time, and continuing to receive and record messages broadcast by other nodes; when the time is up on the timer, the receiving node superimposing waveforms of the message and other messages which have overlap of transmitting time with the message, submitting to the reception and processing flow to be processed. The present invention can realize precise real-time emulation for large-scale network system and support the dynamic adjustment and debugging of network.

Description

technical field [0001] The invention belongs to the technical field of data link networks and relates to a real-time simulation method for link conflicts in data link networks. Background technique [0002] With the wide application of information technology, the data link has become a networked information system that provides reliable and efficient information support for multi-platform joint operations in a complex battlefield environment. At the same time, the scale of the system network continues to expand, and the design of the network protocol is becoming more and more complex. Its functions and performance cannot be fully verified by small-scale physical tests. Validation with network emulation becomes a viable solution. [0003] Traditional network emulation can be divided into real-time emulation and non-real-time emulation. Real-time network simulation generally adopts a hardware-in-the-loop method. The simulation software is responsible for the upper-layer test...

AI Technical Summary

Problems solved by technology

Real-time network simulation generally adopts a semi-physical method. The simulation software is responsible for the upper-layer test service sending and receiving and statistics, and the lower-level message sending and receiving is completed by the installed equipment. This method is limited by the number of installed equipment, and it is difficult to support large-scale network simulation.

Non-real-time simulation generally needs to set the simulation scene and business model before the simulation, and the simulation program independently completes the simulation process and outputs the results. Human intervention cannot be performed during the simulation process, and it cannot support dynamic adjustment and debugging during network operation.
