This paper is concerned with the problem of reliability-aware embedding of Virtual Networks (VN), where substrate nodes exhibit heterogeneous and independent failure rates. In this context multiple problems emerge, particularly the concern of estimating the reliability of a VN. Further, a reliable embedding solution may result in a service with over-provisioned reliability (hence waste of network...
Cloud computing has become a cost-effective model for deploying online services in recent years. To improve the Quality-of-Service (QoS) of the provisioned services, recently a number of proposals have advocated to provision both guaranteed server and network resources in the form of Virtual Data Centers (VDCs). However, existing VDC scheduling algorithms have not fully considered the reliability...
