Performance Study of Multi-Queue Pipeline Architecture for Software-Defined Network Controller

MasterSoftware-defined network (SDN) has become one of the most promising technologies in enterprise and telecommunication fields. Particularly, network systems in data centers need this technology as traffic is getting much higher because of the explosion of mobile service demands. We propose a multi-queue pipeline architecture that can be applied to software-defined network controllers. The pipeline architecture has multiple queues between its stages and those queues have a router in the producer’s side to put packets into queues and a scheduler in the consumer’s side to take packets out of queues. We used four different types of policies to route and schedule, then analysed the effects using Queuing theory. For evaluation we used open-source Floodlight controller as an SDN controller and Cbench as a test network. The evaluation showed that the results conformed to the Queuing analysis and that certain pairs of policies made better performance than others
