However, Tracealyzer can often be intrusive and is only applicable to embedded systems themselves, not networked embedded systems
Therefore, Tracealyzer is not suitable for endpoints communicating over the network

Abstract

There is provided mechanisms for analyzing event based behavior of end-points of a network in an industrial system. A method is performed by a control node. The method comprises collecting(S102), from the end-points, timestamped event log entries as created by the end-points within a time window. Each respective timestamped event log entry pertains to a respective event performed by one of the end-points. The method comprises identifying (S106) tuples of correlated events by comparing the timestamped event log entries to each other, thereby providing a mapping between the events and those end-points where the events of each tuple of correlated events are performed.

Description

technical field [0001] Embodiments presented herein relate to a method, a control node, a computer program and a computer program product for analyzing event-based behavior of endpoints of a network in an industrial system. Background technique [0002] Time Sensitive Networking (TSN) is an emerging standard that aims to make Ethernet real-time capable. TSN supports coexistence of different traffic classes / priorities on the same network while ensuring deterministic end-to-end behavior. The mapping of different traffic classes and priorities is done by assigning so-called VLAN tags (where VLAN is an abbreviation for Virtual Local Area Network) (see IEEE 802.1Q (often called Dot1q)) and MAC addresses (where MAC is an acronym for Media Access Control). According to an example, IEEE 802.1Q adds a 32-bit field between the source MAC address and the EtherType field of the original frame. This 32-bit field includes Tag Protocol Identifier (TPID), Tag Control Information (TCI), P...
