Abstract
In recent years, due to the emergence of Software-Defined Networking(SDN), it makes the management of network more convenient and the execution of network policy easier and more flexible. In this thesis, we build up the environment of SDN and use the wireless transmission as the link to offload some network traffic of wired links. As we tell from the result, the congestion and latency issues caused by large flows to small flows can be fundamentally solved with the cooperation of SDN and wireless transmission. Besides, we also adopt local routing policy to reduce the number of flow setup requests that controller needs to deal with from switches so that we can keep controller away from serious overloading status because of a large number of requests. Although local routing policy substantially releases the load of controller, controller’s ability of fine-grained flow view becomes weaker as well. Therefore, we are going to take the advantage of efficient hybrid usage between DRAM and TCAM on the switches to not only reduce controller’s load but also keep the ability of fine-grained flow view in the future.
