Networked Systems
The area examines how distributed technical components remain understandable and manageable under delays, connection losses and inconsistent data.
Research question
How can distributed technical components remain understandable and manageable when faced with delays, connection losses and inconsistent data?
Distributed technical systems have to stay traceable even when connections drop, messages arrive late or data models use different meanings. The Networked Systems research area classifies such disturbances, describes them in protocol models and examines them with trace analysis, fault injection and schema validation.
Three projects run in the scenario: Restart Recovery of Distributed Status Messages (completed in the scenario), Data Buffering for Interrupted Energy Metering (ongoing) and Semantic Checking Between Maintenance Systems (planned). All statements refer to scenarios and synthetic data.
Projects in this area
- P01
Restart Behaviour of Distributed Status Messages
The project compares restart rules that make outdated status messages recognisable after a connection loss. Completed in the scenario; outputs are illustrative.
Completed - P02
Data Buffering for Interrupted Energy Metering
The ongoing project compares two buffering strategies for measurement series that contain gaps, duplicates or misplaced values after offline phases.
Ongoing - P03
Semantic Checking between Maintenance Systems
The planned project examines which semantic errors in data exchange between maintenance systems can be detected beforehand using explicit schema and unit rules.
