Software-Defined Networking (SDN) and Network Function Virtualization (NFV) are two new paradigms which can accelerate service provisioning. Specifically, NFV decouples proprietary network functions from the hardware and implements them in the form of software which is referred to as Virtual Network Function (VNF). In this way, NFV offers great flexibility for service composition and provision. SDN...
The feasibility, scalability and performance of Internet-oriented Software Defined Network (SDN) are confronted with severe challenge, so it needs multiple controllers that influence every aspect of SDN performance. An effective placement algorithm of these controllers is especially important. In this paper, we formulate the Multiobjective Optimization Controller Placement (MOCP) problem and focus...
This paper presents a design method to solve the problems of high failure rate and sorting inefficience in the current cigarette sorting system by integrating RFID technology with CAN BUS. Based on the features of high speed of data transmission, real-time and high reliability, CAN BUS intelligent node is designed. RFID technology enhances the speed and efficiency of cigarette identification. Meanwhile,...
