Procedure for analyzing disturbances of a flow of real-time data in a data network, communication system and computer control.

摘要

Procedure for fault analysis of a data stream in real-time, isochronous, in a data network (100) by a control unit (16) in the data network (100), comprising the following phases, which are made by the control unit (16): receiving data packets of the data stream isochronous real-time generation of a timestamp for each data packet transmitted between two communication devices (10, 12) of the network data (100), so that timestamps characterize the time point of arrival of a corresponding data packet to the control unit (16) determining a frequency distribution of the time difference brands time each in the data packets of the data stream isochronous real time that reach the control unit (16) of the data stream isochronous real-time from timestamps of the data packet, check the distribution of frequencies time difference timestamps each other in the data packets arriving at the control unit (16) of the data stream isochronous real-time, according to a pattern, compared to an ideal state of data flow in time Real isochronous, so that employers allow identification of specific failures in communication devices (10, 12) and the network data transmission (14) connecting communication devices, and determination of the place or cause the transmission failure of the data stream isochronous real-time data network, based on the result of checking of the frequency distribution in a pattern.
