Abstract [en]

Network Function Virtualization (NFV) is a promising solution for telecom operators and service providers to improve business agility, fast deployment of new services and cope with the increasing traffic volume and service demand. To benefit from the advantages of NFV, virtual network functions (VNFs) needs to be provisioned with sufficient resources and function without impacting network quality of service (QoS). To this end, in this paper, we propose a model for VNFs placement and provisioning optimization taking into account latency requirements of the service chains. Our goal is to optimize resource utilization in order to reduce cost and to prevent violation of QoS requirements such as end-to-end latency. We present a fine-grained latency model including virtualization overhead, unlike previous works. The model converges in a reasonable time and provides placement solutions ensuring QoS guarantees.
