Software Defined Networks

Overview:

Due to the proliferation of mobile devices such as smart phones and tablet computers, and increase in the speed of network devices to forward data, the Internet traffic has increased many folds compared to a decade ago. Energy consumed by network devices handling the network traffic has increased many fold also. Researchers are not only focusing on battery oriented network such as wireless sensor and ad hoc networks on saving battery power to extend network life but are also focusing on wired network to save energy consumed by  network devices. Energy consumed by wired network can be reduced by putting underutilized network devices or links to sleep. If a network device has a few links such as a backbone network device, it is better to consider underutilized device to put to sleep, but if a network device has many links such as in data centers network devices and campus networks devices, it is better to consider underutilized links to put to sleep. In this project, we consider putting underutilized links to sleep. Off course, if all links of a network device are put to sleep, the  device itself will be put to sleep. Furthermore, in this project, we consider OpenFlow-based network as it is software defined network and flexible to control network devices. Besides, OpenFlow is being standardized by big enterprises such as NEC, Google, Cisco, Microsoft etc. Our goal is to evaluate the software define network by using small scale tesbed and simulation, and compare its performance with traditional networks in terms of energy efficiency, speed, and carbon emission.
