Software defined networks (SDN) is perceived to have specific capabilities for utilization by network infrastructures automatically. The success of OpenFlow protocol is to decouple control plane from data plane completely. However, current SDN still regards the network as a group of devices rather than a holistic resource, and traffic monitoring and control only relies on network states but not including...
Fog computing is considered as a trend for future wireless sensor networks (WSNs) due to low latency and energy-saving. However, because different fog services have different quality of service (QoS) requirements and related data are forwarded by content-aware traffic control, it is a must for fog computing advanced WSNs to deploy QoS policy dynamically. Software-Defined Networking (SDN) is a future...
Software-defined Home Networks (SDHN) is a key development trend of smart home which is proposed to realize multi-home visual sharing. With the improved openness and programming ability, SDHN faces increased network threat than traditional home networks. Especially, because of the diversity and heterogeneity of smart home products, multi-stage attack is more convenient to be performed in SDHN. To...
Traffic forwarding is a fundamental function in network operations. And forwarding traffic dynamically according to the current situation is attractive to network providers. With its programmability, Software-Defined Networks (SDN) provide network providers dynamic traffic forwarding ability. But SDN only provides trivial flow table to control traffic forwarding that is not an effective way for applications...
Distributed denial-of-service (DDoS) flood attack is one of the most popular techniques taken by the hackers to threaten the availability and stability of the Internet. To ensure network usability and reliability, accurate detection of this kind of attack is critical. In this paper, we propose a statistical DDoS flood attack detection method by passively monitoring the abrupt change of network traffic...
In view of the specific features of the current harmonic monitoring system, especially the difficulty in realizing complex algorithms, a new method which adopts S3C2410 and embedded Linux platform to construct a new harmonic monitoring system is designed in this paper. It also provides graphic user interface by using QT/Embedded library and harmonic compensation system based on the improved method...
