本文提出了一种用于软件定义无线接入网络（SDWAN）的新型基于多路径通信的OpenFlow通道，即mOpenFlow。mOpenFlow的优点包括：（i）无线环境中的弹性和可扩展性，（ii）现有接入网络和OpenFlow标准的可演进性，（iii）用于mOpenFlow性能分析的新型网络演算模型。通过对用于传送OpenFlow流量的多路径通信进行延迟，mOpenFlow增强了鲁棒性（即，弹性）和吞吐量（即，可伸缩性）。为了实现可演化性，mOpenFlow采用了符合SDWAN和OpenFlow标准的多路径传输控制协议。我们评估mOpenFlow在仿真SDWAN中与标准通道的关系。结果表明，mOpenFlow在鲁棒性和可扩展性方面都优于标准通道。仿真结果表明，该模型为分析mOpenFlow上的端到端延迟提供了一种快速可靠的方法。(C)2016年6月，作者。爱思唯尔有限公司出版
This paper presents a novel multipath communication-based OpenFlow channel for Software Defined Wireless Access Networks (SDWANs), namely mOpenFlow. The advantageous features of mOpenFlow include the following: (i) resilience and scalability in wireless environments, (ii) evolvability of the existing access networks and the OpenFlow standard, (iii) a novel network calculus-based model for performance analysis of mOpenFlow. By lever-aging the multipath communication for conveying OpenFlow traffic, mOpenFlow enhances both robustness (i.e., resilience) and throughput (i.e., scalability) of the control channel. To achieve the evolvability, mOpenFlow adopts the multipath transport control protocol, which conforms to SDWANs and the OpenFlow standard. We evaluate mOpenFlow in an emulated SDWAN in relation to the standard channel. The results show that mOpenFlow outperforms the standard channel, both in terms of robustness and scalability. Additionally, the numerical results indicate that the model provides a fast and reliable way for analyzing the end-to-end delay on mOpenFlow. (C) 2016 The Authors. Published by Elsevier Ltd.
