A Generic Approach to Dependability in Overlay Networks
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.
