中文摘要: IETF提出的服务功能链(Service Function Chain,SFC)解决了服务功能在部署过程中网络拓扑与硬件设备紧密耦合、灵活性差等问题,其中,NSH协议用于支持服务功能链的实现.然而,标准的OpenFlow协议对NSH协议支持不足、实现过程复杂且实现后造成兼容性等问题.本文基于软件定义网络(Software Defined Network,SDN)和网络功能虚拟化(Network Function Virtualization,NFV)技术,根据IETF规定的相关标准,提出一种基于协议感知转发(Protocol Oblivious Forwarding,POF)的服务功能链,利用POF在数据平面深度可编程的能力实现NSH协议.文中基于FloodLight控制器和POF交换机实现了该服务功能链,实验结果表明,基于协议感知转发的服务功能链可以高效地实现服务功能的部署.
Abstract:The Service Function Chain (SFC) proposed by the IETF solves the problems that the service functions are tightly coupled with the hardware devices and have poor flexibility in the deployment process. The NSH protocol is used to support the implementation of the SFC. However, the standard OpenFlow protocol is not sufficient to support the NSH protocol and causes the problems of compatibility after implementation. Based on Software Defined Network (SDN) and Network Function Virtualization (NFV) technologies, this study proposes an SFC based on Protocol Oblivious Forwarding (POF), which implements the NSH protocol using the ability of POF that can be programmed deeply in the data plane. In this study, we implements the SFC based on FloodLight controller and POF switch. The experimental results show that the SFC based on POF can efficiently implement the deployment of service functions.
