In this letter, we propose a mathematical model for the controller placement problem in Software Defined Networks (SDN). More precisely, given a set of switches that must be managed by the controller(s), the model simultaneously determines the optimal number, location, and type of controller(s) as well as the interconnections between all the network(More)
In this paper, we evaluate the effect of different queueing disciplines and different codecs on a voice over IP (VoIP) network with video (also known as video conference). A real network topology is implemented using Cisco equipment. Experimental results show that low latency queueing (LLQ) and AutoQoS can provide significant improvements over FIFO in terms(More)
