Abstract

This paper proposes a novel method of UDP multi-pathization with SDN for NFS. Although current UDP protocol, which is one of the transport layer protocol of NFS, cannot handle multiple paths simultaneously, the proposed method can multi-pathize UDP by utilizing SDN without any changes of current TCP/IP protocols. The method distributes packets over multiple paths according to the congestion of the paths and the length of IP packets. Since the control is performed on SDN, no changes of existing protocols, softwares, and devices are required. The authors implemented their method by using OpenFlow and IoT devices, Raspberry Pi 3 as SDN protocols and IoT devices, respectively; they then confirmed the effectiveness of the proposed method by actual experiments.

基于SDN的NFS协议UDP多路径化方法的研究
提出了一种基于SDN的NFS协议UDP多路径化新方法。虽然目前的UDP协议是NFS的传输层协议之一,无法同时处理多条路径,但本文提出的方法可以在不改变现有TCP/IP协议的情况下,利用SDN实现UDP的多路径化。该方法根据路径的拥塞情况和IP报文的长度,在多条路径上分配报文。由于控制是在SDN上执行的,因此不需要更改现有的协议、软件和设备。作者分别使用OpenFlow和物联网设备,树莓派3作为SDN协议和物联网设备来实现他们的方法;然后,他们通过实际实验证实了所提出方法的有效性。
