The RON/IRIS Testbed

• The RON/IRIS host list. The script outputs XML that is suitable for automated parsing, formatted for display using XSLT.

About the Testbed

The RON testbed consists of 35+ machines scattered around the Internet. These nodes are used for measurement studies and evaluating distributed systems. The testbed arose from the DARPA-funded Resilient Overlay Networks project. At the time, we needed to measure the actual availability of Internet paths, and no existing testbed provided us with the capability or scale we needed.

Today, the RON testbed is used by a number of research groups from universities around the US and the world for networking research. Projects using it range from those conducting "pure" network measurement to projects such as Project IRIS, which is using the testbed to deploy multi-terabyte distributed applications.

Access to the RON testbed is brokered through Emulab. To use the testbed, you must:

• Create (or join) a project at Emulab that has RON testbed ("widearea") access.
• Send email explaining why you need access to the testbed, and how you will use it. Please explain the experiments you plan to conduct, with an emphasis on who they will contact and how much capacity they will use and how often.

The RON testbed has "up-front admission control" (a.k.a., we try to manually ensure that not too many people are consuming resources at any given time). As a result, this means that the RON testbed nodes are generally very lightly loaded, but it also means that everyone has to work to cooperate and keep the loads that way.

Funding

Funding for the RON testbed has come from DARPA and from the National Science Foundation, for whose support we are very grateful.
