摘要

在OpenStack中，覆盖L2路由和覆盖底层L3路由涉及到主机的TCP/IP栈、iptables规则和Linux内核的使用。本文介绍了一种网络模块，它可以最大限度地减少主机TCP/IP栈的负载，并且不依赖于iptables规则/ Linux内核进行网络连接。本文通过软件定义网络(SDN)实现了OpenStack的网络模块neutron的网络代理的概念验证(POC)。本文实现了一种覆盖L2网络的方法，利用OVS (Open vSwitch)和OpenFlow协议对Neutron的路由实例进行虚拟化。本文旨在探讨在OpenStack中使用SDN技术实现网络功能和网络虚拟化的范围。本文通过比较POC与现有OpenStack设置的TCP带宽测量方面的网络性能来结束。

Networking agent for overlay L2 routing and overlay to underlay external networks L3 routing using OpenFlow and Open vSwitch

Overlay L2 routing and overlay to underlay L3 routing in OpenStack involves usage of Host Machine's TCP/IP Stack, iptables rules and Linux Kernel. This paper introduces a networking module which minimizes load on Host TCP/IP Stack and is independent of iptables rules / Linux Kernel for networking. This paper implements Proof-of-Concept (POC) of a networking agent for OpenStack's Networking Module-Neutron via software-defined networking (SDN). This paper implements a method for overlay L2 networking, overlay to underlay L3 routing and virtualizes Neutron's routing instance using Open vSwitch (OVS) and OpenFlow protocol. This paper aims to explore the scope of implementing the networking functionalities and network virtualization using SDN technologies in OpenStack. This paper concludes by comparing networking performance in terms of collective TCP bandwidth measurement of the POC against the existing OpenStack setup.
