Abstract

We build a research testbed at our campus with real users, namely all the members of the university, to bridge the gap between synthetic mesh testbeds and productive mesh deployments. This requires combining the flexibility of research-only testbeds with the high reliability of production networks. This paper shows how we bring these two contradicting design goals together, given the degree of flexibility we demand calls for the ability to exchange the implementation of possibly all layers of the network stack. Given the experimental nature of the environment, we expect frequent software failures. However, we argue our failsafe architecture can still limit the impact of such failures to a satisfactory level of user experience.
