基于SDN的回程网络中节能业务分配的理论与实现

Energy-efficient Traffic Allocation in SDN-based Backhaul Networks: Theory and Implementation

Senay Semu Tadesse, Claudio Casetti, Carla Fabiana Chiasserini

摘要:

预计5G网络将具有高能效,能耗比目前的系统低10倍。实现这样的目标的有效方式是通过控制节点的操作状态和业务流的分配来作用于回程网络。为此,在本文中,我们制定能源效率的流路由的回程网络作为一个优化问题。鉴于其复杂性,这会损害大规模场景中的解决方案,然后我们提出了一种启发式方法。我们的计划,名为EMMA,旨在关闭空闲节点和集中流量的最小可能的一组链路,这反过来又增加了空闲节点的数量。我们在ONOS上实现EMMA,并通过Mininet仿真网络得出实验结果。我们的研究结果表明,EMMA提供了良好的节能性能,接近最佳。在更大的网络场景中,EMMA提供的能耗增益相对于所有节点都处于活动状态的简单基准非常高,在中低流量负载下几乎达到1。

英文摘要:

5G networks are expected to be highly energy efficient, with a 10 times lower consumption than today's systems. An effective way to achieve such a goal is to act on the backhaul network by controlling the nodes operational state and the allocation of traffic flows. To this end, in this paper we formulate energy-efficient flow routing on the backhaul network as an optimization problem. In light of its complexity, which impairs the solution in large-scale scenarios, we then propose a heuristic approach. Our scheme, named EMMA, aims to both turn off idle nodes and concentrate traffic on the smallest possible set of links, which in its turn increases the number of idle nodes. We implement EMMA on top of ONOS and derive experimental results by emulating the network through Mininet. Our results show that EMMA provides excellent energy saving performance, which closely approaches the optimum. In larger network scenarios, the gain in energy consumption that EMMA provides with respect to the simple benchmark where all nodes are active, is extremely high, reaching almost 1 under medium-low traffic load.
