Virtualized networks allow for simultaneous control
of different types of network, computation, and storage
resources. As a result, resilience is not bound to a
specific type of resource such as protection or restoration
in the scope of a network. It rather enables concerted
reactions on failures, such as traffic redirection on a
joint infrastructure with multiple network and server domains.
After summarizing outage issues in information and communication infrastructures, the talk exhibits resilience concepts in network virtualization that enable providers to realize reliable services efficiently. Recent research results are then presented, including design models, comparisons between architectural options, and provisioning of cloud services.
