Fehlertolerante Overlay-Netze mit programmierbaren Netzknoten

for the yearbook This thesis describes adaptive multi-dimensional fault tolerance as a network service in Programmable Networks. We outline the concept of a component based programmable node architecture. Based on this performant and fault tolerant plattform we introduce scalable fault tolerance as a transparent network service. The foundation of the service are cooperating transparent overlay networks, located on gateways, which organize the provision of redundancy. Scalabilty of our approach is given through the topological separation of service signaling and dynamic fault masking. Furthermore our flow based approach integrates application specific adaptive fault tolerance in the proposed network service.
