摘要
The current trend is to integrate a constantly increasing number of services in the same communication network. Some services have very high resilience requirements, while other services have lower ones. This scenario calls for frameworks capable of provisioning for multiple services in a cost-efficient manner, and already a large number of frameworks has been proposed in the literature. This article presents a comprehensive survey of research efforts related to resilience differentiation in the Internet and telecommunications networks. We present a general framework classification which is used as the basis for the subsequent review of the relevant literature. Finally, a critical evaluation of the state-of-the-art and future challenges facing operators and designers is given.
