论文摘要
软件定义的网络（SDN）是一种有效控制和管理计算机网络的新兴技术，例如在数据中心，广域网络（WANS）以及无处不在的通信中。在本文中，我们探讨了以SDN控制器和虚拟开关代表的嵌入SDN组件的想法，以提高网络性能。特别是，我们考虑具有不同链接容量方案的最终主机上的多个网络接口之间的负载平衡。我们已经根据OpenFlow软件开关探索并实施了不同的基于SDN的负载平衡方法，并证明了这种方法的可行性和潜力。已通过多径传输控制协议（MPTCP）评估了所提出的系统。我们的结果表明，与传统单网络方法相比，与MPTCP相比，将SDN概念应用于多型设备上的SDN概念，从而增加了55 \％的吞吐量和10 \％。
Software Defined Networking (SDN) is an emerging technology of efficiently controlling and managing computer networks, such as in data centres, Wide Area Networks (WANs), as well as in ubiquitous communication. In this paper, we explore the idea of embedding the SDN components, represented by SDN controller and virtual switch, in end-hosts to improve network performance. In particular, we consider load balancing across multiple network interfaces on end-hosts with different link capacity scenarios. We have explored and implemented different SDN-based load balancing approaches based on OpenFlow software switches, and have demonstrated the feasibility and the potential of this approach. The proposed system has been evaluated with multipath transmission control protocol (MPTCP). Our results demonstrated the potential of applying the SDN concepts on multi-homed devices resulting in an increase in achieved throughput of 55\% compared to the legacy single network approach and 10\% compared to the MPTCP.
