A test method for analysing disturbed ethernet data streams

M. Kreitlow, F. Sabath, and H. Garbe

Abstract. Ethernet connections, which are widely used in many computer networks, can suffer from electromagnetic interference. Typically, a degradation of the data transmission rate can be perceived as electromagnetic disturbances lead to corruption of data frames on the network media. In this paper a software-based measuring method is presented, which allows a direct assessment of the effects on the link layer. The results can directly be linked to the physical interaction without the influence of software related effects on higher protocol layers. This gives a simple tool for a quantitative analysis of the disturbance of an Ethernet connection based on time domain data. An example is shown, how the data can be used for further investigation of mechanisms and detection of intentional electromagnetic attacks.

Short summary
Ethernet connections can suffer from data corruption due to intentional electromagnetic interference. In this paper a software-based measuring method is presented, which allows a direct assessment of the effects on the link layer without an unwanted influence of software related effects on higher protocol layers. This gives a simple tool for a quantitative analysis of the disturbance of an Ethernet connection based on time domain data.
