Network test bench
A small test set-up with six logical nodes in which delay and packet loss are controlled and synthetic messages are recorded.
Purpose
The network test bench assesses system behaviour in controlled fault scenarios, for example after connection losses. It serves the projects Restart Recovery of Distributed Status Messages and Data Buffering for Interrupted Energy Metering.
Methods
- Fault injection
- Trace analysis
- Protocol models
Components
- Six logical nodes on small computers or virtual instances
- Control of delay and packet loss
- Recording of synthetic messages
Specifications
- Adjustable delay
- Adjustable packet loss
- Synthetic messages only
Limits
The network test bench is a equipment concept, not an existing, accredited or bookable facility. It does not assess any real power grid or real grid supply. Responsible are Alex Berger and Dr. Tobias Kern.
