Abstract: Software-defined networking (SDN) has recently gained wide interest in datacenter networks for simplification, abstraction, and high-performance. Centralized control means all flow decisions are made at the controller, leaving the network to treat the packets as opaque data. In recent years, SDN has been used for traffic engineering and management, traffic shaping, policy and quality-of-service (QoS) and to increase capacity, reliability and overall performance.When using centralized control, performance and quality-of-service (QoS) of traffic flow management decisions are often sacrificed to maintain simplicity, yet some of the algorithms proposed for SDN are highly complex and difficult to analyze. A simple, scalable, and closed-form solution to these issues could accelerate the widespread adoption of SDN. In this paper, we propose a set of simple QoS policies for centralized SDN using Linear Programming (LP). We use a downlink local area network (LAN) traffic model to demonstrate QoS improvement, and this is compared to the state-of-the-art, and show lower end-to-end delay.

Abstract: The aim of this paper is to study the performance of an end-to-end networking scheme based on multichannel and multihop Erlang B networks. In order to improve the network performance, we propose a channel assignment based on the Dijkstra shortest path algorithm. In the simulation, we find that the multihop Erlang B network with 300 nodes achieves a higher level of performance than a single channel Ethernet network and a three-level tree network. However, for larger scale networks, the tree network has better performance with less overhead. Additionally, we compare the policy of each node with the global maximum channel use and find that the nodes' policies as a whole are not as reliable as global maximum channel use.
