[0016] Terminology Explanation

[0017] AFDX: Avionics Full Duplex Switched Ethernet, avionics full duplex switched Ethernet, transforms switched Ethernet into a deterministic network that can be used in mission-critical systems. The network is standardized by the ARINC 664 part 7 specification and has become the primary avionics integration network for the Airbus A380 and Boeing 787 aircraft.

[0018] VL: Virtual Link, a virtual link defines a logical one-way connection from one source to one or more destination end systems. A virtual link is composed of one or more sub-virtual links. Each virtual Links are assigned a maximum bandwidth, which is allocated by the system integrator.

[0019] BAG: Bandwidth Allocation Gap, BAG defines the minimum time interval between the starting positions of two adjacent frames in the same VL.

[0020] ICD: Interface Control Document, interface control file.

[0021] ES: End System, the end system, the end system is embedded in the avioni...

Abstract

The embodiment of the invention provides a method for testing an end system in a network, and the method comprises the following steps: configuring a simulation unit of the end system for correspondingly performing communication with the end system; acquiring end communication data of the end system; testing the end communication data; and acquiring and showing the analysis result of the end communication data through a monitoring module. Through the scheme, the systematic property and degree of automation of AFDX (avionics full duplex switched Ethernet) network testing are improved.

Description

technical field [0001] The invention relates to the testing field of network systems, in particular to a testing method applicable to end systems and switching units in avionics full-duplex Ethernet. Background technique [0002] Avionics Full Duplex Switched Ethernet (AFDX) is a network interconnection technology suitable for large and medium-sized aircraft avionics systems. It uses single network segment, full duplex, access and backbone switching, and virtual chain Technologies such as road traffic isolation solve the requirements of integrated interconnection for network capacity, scalability, and real-time performance. Compared with ARINC429 and other aviation communication networks, such as MIL-STD-1553B, AFDX has great advantages in speed, communication mode, information type, etc., and reduces the number and weight of various connections. AFDX is the latest product in today's avionics bus products, and it will also be the mainstream of future avionics bus products. ...
