SDN控制器广播风暴对比实验部署

编者按：环路广播风暴，如果有环路，数据帧将会在环路中来回传递，大量增生数据帧，形成广播风暴。在SDN中部分控制器可以抑制环路广播风暴的产生，如Floodlight，而像POX控制器，就不能很好的解决广播风暴的问题。

SDN控制器广播风暴对比实验部署

接下来将对Floodlight和POX控制器进行广播风暴实验的对比。

SDN控制器广播风暴对比实验部署

物理连接上OF1、OF2、OF3形成环路，使用Flowvisor（192.168.20.6:6634）隔离成两个虚网。VM1和VM3在一个虚网中，由POX（192.168.20.6:6635）控制，VM2和VM3在另一个虚网中，由Floodlight（192.168.20.6:6636）控制。

POX安装与配置

安装：

Shell

git clone http://github.com/noxrepo/pox

启动：

Shell

./pox.py forwarding.l2_learning openflow.of_01 --port=6635

Floodlight安装与安装

安装：

Shell

apt-get install build-essential default-jdk ant python-dev git clone git://github.com/floodlight/floodlight.git

ant;端口配置：

Shell

vi ./src/main/resources/floodlightdefault.properties

启动：

Shell

nohup java -jar target/floodlight.jar > /dev/null &

Flowvisor安装与配置

安装：

Shell

sudo apt-get install ant  sudo apt-get install openjdk-6-jdk wget https://github.com/OPENNETWORKINGLAB/flowvisor/archive/1.2-MAINT.zip make && make install

端口配置

Shell

vi /etc/flowvisor/config.json（目前使用监听端口6634）

普通用户下启动：

Shell

nohup  flowvisor /etc/flowvisor/config.json >/dev/null &

OvS安装与配置

OvS在之前已经写过，详情可查看《 Open vSwitch2.3.0版本安装部署及基本操作》。

创建虚网

创建两个slice，分别指定到POX和Floodlight上：

Shell

fvctl -p 8181 add-slice s1 tcp:127.0.0.1:6635 1@1 fvctl -p 8181 add-slice s2 tcp:127.0.0.1:6636 2@2

修改OvS的dpid：

Shell

192.168.20.3：ovs-vsctl set bridge br0 other_config:datapath-id=1000000000000001 192.168.20.4：ovs-vsctl set bridge br0 other_config:datapath-id=1000000000000002 192.168.20.5：ovs-vsctl set bridge br0 other_config:datapath-id=1000000000000003 root@fnic8:~# ovs-vsctl list bridge br0 _uuid               : 9a7f1e47-b5f1-410f-9a63-0393acf1a651 controller          : [1ab5ceec-3965-47c4-89ab-1f1f408470bb] datapath_id         : "1000000000000001"

查看端口号：

Shell
