Software Defined Network (SDN) is becoming a new paradigm for both WAN and enterprise networks. By separating control and data planes, SDN allows network providers to sell new services without changing their physical switches. One of the key services SDN can enable is network virtualization which allows a service provider to have a virtual slice of a(More)
Software-defined networking (SDN) is fast evolving as a new paradigm for next generation data networking. In SDN, controller is a central piece of its networks, which provides a logically centralized control of the network. Different from the previous studies on Northbound APIs and Southbound APIs of SDN, in this paper, we propose a service oriented network(More)
Outsourcing private data and heavy computation tasks to the cloud may lead to privacy breach as attackers (e.g., malicious outsiders or cloud administrators) may correlate any relevant information to penetrate information of their interests. Therefore, how to preserve cloud users' privacy has been a top concern when adopting cloud solutions. In this paper,(More)
The proliferation of new malware in recent years has presented a serious security threat to our society. Research shows that variants of some known ones take a large amount of new malware, so one of the challenges in malware detection is how to find the similarities between known malware and its variants. Since API(Application Programming(More)
Optical networks are ideal candidates for the future intra- and inter-data center networks, due to their merits of high throughput, low energy consumption, high reliability, and so on. Optical network virtualization is a key technology to realize the deployment of various types of network-based applications on a single optical network infrastructure.(More)
Electronic commerce system for media content distribution has been evolved for decades. Throughout the time, various business models such as business-to-consumer (B2C) and consumer-to-consumer (C2C) are proven to be successful. However, most of the models require players to be tightly bound to the supplier, either tied to its designed web interface or(More)
With the growing need of sharing computing resoures in data-center, various resource management and scheduling schemes have been designed for Hadoop framework. Unfortunately, the Hadoop's existing schedulers (such as Fair and Delayed Fair) suffer from the conflicting nature of fairness and data locality, which can jeopardize system performance. In this(More)
