Intelligent Dependability Services for Overlay Networks [chapter]

Barry Porter, Geoff Coulson, Daniel Hughes

Sharing end-user negative symptoms for improving overlay network dependability

Yongning Tang, Ehab Al-Shaer
2009 2009 IEEE/IFIP International Conference on Dependable Systems & Networks  
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. •  ...

Verme: Worm containment in overlay networks

Filipe Freitas, Edgar Marques, Rodrigo Rodrigues, Carlos Ribeiro, Paulo Ferreira, Luis Rodrigues
2009 2009 IEEE/IFIP International Conference on Dependable Systems & Networks  
Topological worms, such as those that propagate by following links in an overlay network, have the potential to spread faster than traditional random scanning worms because they have knowledge of a subset  ...  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.  ...  [25] propose a model for p2p worms, and analyze the propagation of these worms depending on the attack model (e.g., whether the worm uses the overlay topology or not), and on the structure of the overlay  ...
