Speech Title: Cost-Efficient VNF placement and scheduling in optical datacenter networks

Abstract: We investigate virtual-network-function placement and scheduling problem in optical datacenter networks, considering the installation/de-installation latency of VNF and the rapid variation of low-latency-demands. Further, multipath protection is employed to improve the survivability of service demands. As for small service provider (SPs), it’s impractical to have a large-scall datacenter network, they can customize virtual machines (VMs) provided by public cloud service providers (CSPs). In this case, how to minimize the cost paid to lease resources from the CSP, while meeting the requirements of service demands is an important problem. Hence, we also propose a cost-efficient VPS scheme (CE-VPS) in public cloud networks for dynamic traffic. The proposed schemes achieve good performance in terms of latency, spectrum efficiency, blocking probability, etc.
