Embodiment Construction
[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0041] Discrete event means that the state change of the event is discrete in the event, and the occurrence of the event is considered to be completed in an instant. In the discrete event simulation system, there are no other events between two adjacent events, and the AFDX network can be regarded as a Discrete event systems, therefore, can utilize discrete event mechanisms to simulate AFDX networks. Based on this, the embodiment of the present invention provi...

The invention provides a simulation system and a simulation method of an AFDX (Avionics Full Duplex Switched Ethernet) network. Both an end system and an exchanger in the AFDX network are abstracted into discrete event simulation nodes by adopting a discrete event mechanism, AFDX information is abstracted into discrete events for the discrete event simulation nodes, the transmission behavior of the AFDX information in the end system and the retransmission behavior of the AFDX information transmitted from the end system between different ports of the exchanger are simulated by utilizing the transmission and retransmission behaviors of the discrete events, and performance parameters of the AFDX network can be obtained on the basis of the simulation. According to the simulation system and the simulation method, a real information operation mechanism of the AFDX network is simulated by utilizing the discrete events, so that the performance parameters of the AFDX network after each discrete event is ended can be conveniently counted, the system design of the AFDX network is further optimized, and the iteration cycle of the system design is shortened; additionally, an end system simulation module in the simulation system is automatically introduced on the basis of an interface control document, so that the system verification time is reduced.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to an AFDX network simulation system and simulation method. Background technique [0002] Avionics Full Duplex Switched Ethernet (AFDX) is a standard-based electronic and protocol specification (IEEE802.3 and ARINC 664Part7), which is used to realize data exchange between aviation subsystems. [0003] The topology of the AFDX network is complex. When designing the system, it is necessary to consider the configuration of each end system, switch, and virtual link (Virtual link, VL) to ensure the real-time and reliability of the AFDX network. After the system design is completed, it is necessary to wait for the hardware to be verified, and then iteratively design according to the verification results, so as to ensure that the AFDX network is in the optimal design. [0004] In order to reduce the system iteration cycle, the system simulation of the AFDX network is mainly carried...
