Study of programmability and control of virtual network functions for software defined networks

Abstract

Software-defined networking (SDN) is a concept which decouple network control and forwarding functions. In SDN framework, centralized control of data path elements is enabled independently of the network technology to connect network devices. A mission of SDN is programmable that can be used to automate network configuration. Network function virtualization (NFV) has propose a way for decoupling software from hardware and flexible network function deployment. In this study, I explore and research programmability and control of virtual network functions for software defined networks. My study approach NFV ideas to program and control virtual network functions. First approached network function is Firewall on SDN controller. I would to like to proposal a process to update firewall policy in a cluster controllers. The purpose is that avoids attacks our network via firewall in the period of time when a SDN controller is down. Security is the second virtual function in this study Keywords: Software-defined networking (SDN), Network function virtualization (NFV), Firewall, Security
