Overlay networks are virtual communication structures that are logically “laid over” underlying hosting networks such as the Internet. They are implemented by deploying application-level topology maintenance and routing functionality at strategic places in the hosting network [1,2]. In terms of dependability, most overlays offer proprietary “self-repair” functionality to recover from situations in which their nodes crash or are unexpectedly deleted. This functionality is typically orthogonal to the purpose of the overlay, and a systematic and complete approach to dependability is rarely taken because it is not the focus of the work. We therefore propose to offer dependability as a service to any overlay.
