	abstract = "{NorNet Core is the world's first, open, large-scale Internet testbed for multi-homed systems and applications. Particularly, it is currently used for research on topics like multi-path transport and resilience.
Researchers can run experiments on distributed, programmable nodes that are distributed over various locations and providing access to multiple different Internet service providers~(ISP) with different access technologies.
Clearly, a key feature of this testbed is to work in the real-world Internet. That is, it is especially desired to expose experiments to real Internet behaviour like background traffic. However, for the researcher, it is necessary to actually know how paths -- being used for an experiment -- actually behave: Are the paths actually working? How are the round-trip times among sites over different ISPs, etc.. How did the behaviour change over time?
To provide such information to the researchers, we have designed and developed a maintenance and monitoring infrastructure for the NorNet Core testbed. In this paper, we will first introduce this infrastructure. Furthermore, we will demonstrate its usefulness with some useful, real-world examples. Our infrastructure has now become part of the testbed, and it is therefore available for all users of NorNet Core as well.}",
