ITEM

Isolated Test Environments and Measurements

Motivation

Isolated test environments allow full control and reproducibility of test conditions. Experiments in these laboratories provide detailed insights into the behaviour of network devices. The collected information allow to build models, can be used to explain behaviour and to optimize device performance.

ITEM is a research group for exchanging ongoing research, concepts, and ideas in the device performance and measurement domain. Researchers and students meet once every month to discuss current topics, advancements, tools, and best practices in measurements.

Monthly ITEM meeting

We meet every month for about one hour. Usually each second Monday per month.

The audience of the monthly meetings are:

  • Interested researchers from the chair
  • Interested researchers from other chairs
  • Students currently doing a thesis or project in that area
  • Students who are interested in doing a thesis in that area
