Monitoring structure for supporting data capture of port and virtual link as well as monitoring method thereof

Abstract

The invention discloses a monitoring structure for supporting data capture of a port and a virtual link as well as a monitoring method of the monitoring structure. The monitoring structure for supporting data capture of the port and the virtual link comprises an ARINC66 protocol monitoring engine, a monitoring configuration parameter module, a second input port and a second output port, wherein the ARINC66 protocol monitoring engine is independent with an ARINC664 protocol exchange engine and has an exchange structure inside; the second input port is in charge of acquiring data from a first input port and a first output port of the ARINC664 protocol exchange engine, judging whether the data is captured according to the monitoring configuration parameter module, and submitting the data required to be captured to the exchange structure of the ARINC66 protocol monitoring engine; and the data required to be captured can be exchanged by the exchange structure and is sent from the second output port. According to the invention, mutual independence of the monitoring engine and the exchange engine is guaranteed.

Description

Technical field [0001] The present invention relates to a monitoring technology, in particular to a monitoring structure supporting port and virtual link data capture and a monitoring method thereof. Background technique [0002] Avionic Full-Duplex Switched Ethernet Network (Avionic Full-Duplex Switched Ethernet Network) is a deterministic aircraft data network bus used for information transmission in avionics systems. Aviation full-duplex switched Ethernet is currently widely used in aircraft avionics systems. It uses standard IEEE802.3 technology. The Ethernet hardware equipment, cables, and test equipment used have been widely used and verified by a large number of COTS products. This reduces the cost of the aircraft data bus network. ARINC664 is defined as the next-generation aircraft data network (ARINC664 is defined as the next-generation aircraft data network) and is a part of aviation full-duplex switched Ethernet. The ARINC664 protocol only defines how to manage the st...

AI Technical Summary

Problems solved by technology

However, the ARINC664 protocol switching engine does not provide an interface for users to configure capture parameters, nor does it provide an interface for users to capture data packet loads

Therefore, for the data flowing through the switch, the user cannot know the data content, and the switching engine can only count the number of data packets, which is inconvenient for the user to monitor the system operation and system failure
