ryu与mininet的连接

1.执行控制器端ryu程序

root@ubuntu:/home/renwoxing/Desktop/ryu/ryu/app# ryu-manager  --verbose simple_switch_13.py
loading app simple_switch_13.py
loading app ryu.controller.ofp_handler
instantiating app simple_switch_13.py of SimpleSwitch13
instantiating app ryu.controller.ofp_handler of OFPHandler
BRICK SimpleSwitch13CONSUMES EventOFPSwitchFeaturesCONSUMES EventOFPPacketIn
BRICK ofp_eventPROVIDES EventOFPSwitchFeatures TO {'SimpleSwitch13': set(['config'])}PROVIDES EventOFPPacketIn TO {'SimpleSwitch13': set(['main'])}CONSUMES EventOFPPortDescStatsReplyCONSUMES EventOFPHelloCONSUMES EventOFPErrorMsgCONSUMES EventOFPEchoRequestCONSUMES EventOFPPortStatusCONSUMES EventOFPEchoReplyCONSUMES EventOFPSwitchFeatures

2.mininet启动，配置如下：

root@ubuntu:/home/renwoxing/Desktop# mn --topo single,3 --mac --switch ovsk --controller remote -x
*** Creating network
*** Adding controller
*** Adding hosts:
h1 h2 h3
*** Adding switches:
s1
*** Adding links:
(h1, s1) (h2, s1) (h3, s1)
*** Configuring hosts
h1 h2 h3
*** Running terms on :0.0
*** Starting controller
*** Starting 1 switches
s1
*** Starting CLI:

3.ryu控制器端变化：

connected socket:<eventlet.greenio.base.GreenSocket object at 0x7fe9d10e2a90> address:('127.0.0.1', 59823)
connected socket:<eventlet.greenio.base.GreenSocket object at 0x7fe9d10e2610> address:('127.0.0.1', 59824)
hello ev <ryu.controller.ofp_event.EventOFPHello object at 0x7fe9d10e2490>
move onto config mode
