2In Software Defined Network based Internet of Things (SDN-IoT), the path selected for forwarding the packets as per rules, should be Quality of Service (QoS) effective. Since SDN based IoT involves dynamic heterogeneous flows, handling caching in terms of rules becomes challenging. Hence in this paper, we propose QoS aware Optimum Path Selection and Rule Caching Policy (QOPS-RCP) for SDN based IoT. In this technique, the optimum path is determined that satisfies the QoS constraints: Rule Caching (RC) cost, packet loss probability and delay. A RC policy is designed that matches the requirements of SDN based IoT architecture such that the cost of RC is minimized. The proposed research methodology is implemented in OpenFlow module and the performance is evaluated in terms of throughput and end-to-end delay.

为基于软件定义网络 (SDN) 的物联网 (IOT) 优化路径并降低规则缓存成本

2在基于软件定义网络的物联网 (SDN-IoT) 中,根据规则选择用于转发数据包的路径应该是有效的服务质量 (QoS)。由于基于 SDN 的物联网涉及动态异构流,因此根据规则处理缓存变得具有挑战性。因此,在本文中,我们为基于 SDN 的物联网提出了 QoS 感知最佳路径选择和规则缓存策略 (QOPS-RCP)。在该技术中,确定满足 QoS 约束的最佳路径:规则缓存 (RC) 成本、丢包概率和延迟。RC 策略的设计符合基于 SDN 的物联网架构的要求,从而最大限度地降低 RC 的成本。所提出的研究方法在 OpenFlow 模块中实现,并根据吞吐量和端到端延迟评估性能。
