Thesis title: Optimized VNF (Virtual Network Function) Resource Management in Network Function Virtualization Environments

Supervisors: Albert ZOMAYA , Wei BAO

Thesis abstract:

With the growing demand of clouds and the cloud services, Network Function Virtualization (NFV) is gaining popularity among the application service providers, Internet service providers and cloud service provides. NFV is proving to be an effective and flexible alternative for the service deployments across multiple-clouds. One of the main challenges for deploying NFV is how to efficiently allocate Virtual Network Functions (VNFs) for load balancing, cost reduction and energy saving. A significant amount of work has been already done in the field of VNF management. However, it is still necessary to develop a optimized VNF management model under heavy network load which is generated by several network user equipment due to the emergence of Internet of Things (IoT). The primary goal of this research is to model NFV resource management problem, and develop algorithms for resource efficiency taking into account service quality, cost and energy efficiency. Specifically, the objectives of this research in details are as follows: i) to formulate a QoS-aware VNF management problem; ii) to develop VNF management algorithms to improve overall service quality (minimizing service delay); iii) to formulate a cost-effective VNF management problem; iv) to develop algorithms for VNF operational cost reduction; v) to formulate an energy efficient VNF management problem; and vi) to develop algorithms for energy efficient VNF management.
