In this paper, we study how to provide optimal performance guarantee in multi-resource scenarios, such as Network Function Virtualization (NFV), where Virtual Network Function (VNF) resource demands of one Service Function Chain (SFC) are elastic and correlated with the end-to-end throughput of SFC. Previous works such as Dominant Resource Fairness (DRF) achieve this goal only if the demands are already...
Network Function Virtualization (NFV) transforms the traditional service provision architecture into a software-based structure. In NFV, Virtual Network Functions Forwarding Graph (VNF FG) [1] is used to describe the logic connections among the VNFs placed on the Physical Network (PN). And end-to-end services are represented as flows traverse the VNF FG. To improve the reliability of the services,...
Network Function Virtualization (NFV) is an emerging technology proposed to improve service provisioning in telecommunication industry. The flexibility of NFV enables network operator to dynamically deploy Virtual Network Functions (VNFs) according to real-time requirements. However, a large amount of VNFs with low utilization may be deployed in network due to dynamic arrival and departure of services...
