[0015] Terminology Explanation

[0016] 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 664part 7 specification and has become the primary avionics integration network for the Airbus A380 and Boeing 787 aircraft.

[0017] 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.

[0018] BAG: Bandwidth Allocation Gap, BAG defines the minimum time interval between the starting positions of two adjacent frames in the same VL.

[0019] ICD: Interface Control Document, interface control file.

[0020] ES: End System, the end system, the end system is embedded in the avionic...

Abstract

The embodiment of the invention discloses a network testing device comprising a data acquisition module, an end system testing module, a switching unit testing module and a monitoring module, wherein the data acquisition module is used for coupling a port of a switching unit and/or a port of an end system in a communication way so as to acquire data from the port; the end system testing module is coupled to the data acquisition module and used for carrying out first test on the data acquired from the port of the end system; the switching unit testing module is coupled to the data acquisition module and used for carrying out second test on the data acquired from the port of the switching unit; and the monitoring module is coupled to the switching unit testing module and the end system testing module in the communication way and used for acquiring and presenting the results of the first test and/or second test. Through the scheme, AFDX (Avionics Full-Duplex Switched Ethernet) network design, configuration, deployment and test monitoring are combined so that the systematicness and the degree of automation for an AFDX network test are improved.

Description

technical field [0001] The invention relates to the test field of network systems, in particular to a test device applicable to 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. [0003] But on the other hand, there is...
