Intelligent Dependability Services for Overlay Networks
[chapter]
2006
Lecture Notes in Computer Science
Preserved Fulltext
In this paper we propose generic dependability services which simplify the design of overlays. ...
Application-level overlays have emerged as a useful means of offering network services that are not supported by the underlying physical network. ...
The Resilient Overlay Network project [22] highlights the usefulness of overlays to improve levels of service beyond those of the physical network, but RON is aimed at providing dependable communications ...

The dependability of overlay services rely on the overlay network's capabilities to effectively diagnose and recover faults (e.g., link failures, overlay node outages). ...
However, overlay applications bring to overlay fault diagnosis new challenges, which include large-scale deployment, inaccessible underlying network information, dynamic symptomfault causality relationship ...
monitoring an overlay network is infeasible, overlay fault reasoning has to depend on incomplete and inaccurate information, which unavoidably results to uncertainty in the overlay fault diagnosis. • ...

Furthermore, this worm propagation strategy is likely to become prevalent as the deployment of networks with a sparse address space, such as IPv6, makes the traditional random scanning strategy futile. ...
