At RSSAC's request, the RSSAC Caucus is developing a testbed to simulate resolvers interaction with the root servers. The initial areas of inquiry that were requested by RSSAC are root server selection, priming, and caching, but more areas might be tested later. The testbed will consist of copies of many versions of open source resolvers as well as the ability to test other resolver software such as Windows Server. It will also have mechanisms to model delays between a resolver and the 13 root servers, as well as different contents of the root zone (such as signing with different DNSSEC algorithms).

The development of this system has started, but it is not complete. Instructions for setting up the test bed are open, and it is expected to be completed in fall 2019.

This presentation covers the testbed design, components of the testbed, current status, how researchers can participate in the development of the testbed, and the plan for completing the testbed and running the first sets of simulations.
