US 2006/0215568 A1 · System and method for data collection in an avionics network

Abstract

Systems and methods are provided for data collection in an avionics network. The avionics system comprises a first network switch having an output and a plurality of network inputs and a monitor unit coupled to the output of the first network switch. Each of the plurality of network inputs is configured to couple with a line replaceable unit (LRU). The first network switch is configured to receive a first data from a first LRU via a first network input of the plurality of network inputs of the first network switch, and copy the first data to produce a first copied data. The monitor unit is configured to receive the first copied data from the first network switch. The method comprises the steps of copying the data frames received by a switch from an end system for each of the switches in a deterministic switched network to produce copied data frames at each of the switches in the deterministic switched network, and receiving the copied data frames from a set of switches of the switches in the deterministic switched network at a monitor unit.
