Abstract

The invention relates to a time-triggered Ethernet simulation system. The system comprises a network planning unit, a network scheduling unit, a communication simulation unit and a time synchronization simulation unit; the network planning unit comprises a network topology planning module for generating a network topology file, a network traffic configuration module used for configuring network traffic parameters and each traffic transmission path; the network scheduling unit is used for generating a network scheduling table meeting a set network constraint condition according to network topology information and traffic information; the communication simulation unit is used for realizing the communication simulation of different types of services; and the time synchronization simulation unit is used for realizing message curing, compression, clock synchronization service, cluster monitoring, and state machine clock synchronization. The system of the present invention is more comprehensive and in-depth than the prior art that only simulates a time synchronization function.

Description

technical field [0001] The invention belongs to the technical field of communication networks, and in particular relates to a time-triggered Ethernet simulation system. Background technique [0002] With the rapid development of aviation and aerospace electronic technology, the traditional bus can no longer meet the technical overall design requirements of new aviation and aerospace electronic systems, so the current traditional bus technology is gradually being replaced by the new generation of aviation data bus technology. The bus used by the electronic system in the military aerospace project has begun to shift to Fiber Channel (Fiber Channel, FC), avionics Full-Duplex Switched Ethernet (Avionics Full-Duplex Switched Ethernet, AFDX), SpaceWire, Time-triggered Protocol ( TTP) and Time-triggered Ethernet (TTE). Compared with the traditional bus, the new-generation bus technology can provide higher bandwidth, higher reliability and low delay, which can well meet the technic...
