架构

Floodlight不仅仅是一个支持OpenFLow协议的控制器（FloodlightCOntroller），也是一个基于Floodlight控制器的应用集。

当用户在OpenFLow网络上运行各种应用程序的时候，Floodlight控制器实现了对OpenFLow网络的监控和查询功能。

图0.0显示了Floodlight不同模块之间的关系，这些应用程序构建成java模块，和Floodlight一起编译。

同时这些应用程序都是基于RESTAPI的。

开始

安装指导

概述

基于Java的Floodlight可以用标准jak工具或ant编译运行，当然也可以有选择性的在Eclipse上运行。

准备工作

Linux：

●Ubuntu10.04（Natty）及以上版本（运行Ant1.8.1及以下版本）

●安装JDK，Ant。

（可在eclipse上安装）

$sudoapt-getinstallbuild-essentialdefaultantpython-deveclipse

Mac

●Mac系统x10.6及以上版本（低版本未测试）

●Cxode4.1或Xcode4.0.2

●JDK:

只需要在终端输入命令：

‘javac’便可安装

●Eclipse（非必须）

下载编译

从Github下载并比编译Floodlight

$gitclonegit:
