Software-Defined Networking (SDN) has great potentials in changing the fragile and complex enterprise networks. One operational challenge to SDN deployment is the settlement of legacy switches. A hybrid SDN consisting of both SDN and legacy switches may be a tradeoff. Nevertheless most of the current SDN control planes can not handle legacy switches. To overcome this problem, we present HybridFlow,...
A new method is proposed for a ground telecontrol/telemetry terminal processor design. The design is based on ATmega1280 + FPGA structure, and data exchange is realized through multiple external interruptions between ATmega1280 and FPGA. It elaborately gives the terminal's system composition; external RAM R/W, external interrupt, A/D converter, timer and serial interrupt routine design in ATmega1280...
The researches and applications for digital watermarking technology are more and more extensive, at present, they mainly embodied in the watermark image, video watermarking, as well as voice in areas such as watermarks. This paper based on the popular image scrambling in the Arnold transform method gives the image on the protection of digital watermarking algorithm, the embedded watermark information...
