Most of the networks are generallyless energy efficient and most of the time re-sources are underutilized. Even resources ofbusy networks are also underutilized and thusnetworks show energy inefficient managementsystem. This paper focuses on how to obtainminimum resources for the current situation ofthe network to maintain connectivity, powersaving and quality of service. Four differentmodels ar...

Software-Defined Networking (SDN) has been a hot topic for future network development, which implements the different layers of control plane and data plane respectively. Despite providing high openness and programmability, the “three-layer two-interface” architecture of SDN changes the traditional network and increases the network attack nodes, which results in new security issues. In this pa...

Recently, integrating Softwaredefined networking(SDN) and network functions virtualization(NFV) are proposed to address the issue that difficulty and cost of hardwarebased and proprietary middleboxes management. However, it lacks of a framework that orchestrates network functions to service chain in the network cooperatively. In this paper, we propose a function combination framework that can dy...
