Ryu Modify the listener port Mininet in the custom self-built topology and connect to the specified controller command to interpret

1, Ryu controller modify the listening port

The ofproto_common.py under the Ryu/ryu/ofproto

The following changes, thank you @ BEIJING-Otaku small @ Lone Shrimp

2, mininet in custom self-built topology and connect to the specified controller command interpretation

If you want a simple self-built topology on the mininet, just build it under Mininet/custom, and you can finally name the. py file.The command running is MN--custom self-built topology file name--topo Mytopo If you specify a controller that needs to be connected, you can add a connection parameter mn--custom self-built topology file name--topo Mytopo--controller Remote,ip=ipa Ddr,port=port, that's it. Another detailed step for a self-built topology can be found in the links: http://www.muzixing.com/pages/2013/12/06/ Yuan-chuang-mininetda-jian-zi-ding-yi-wang-luo-tuo-bu-by-muzi.html
One thing to note is that MN is the command to start Mininet,--topo,--custom,--controller are the options you want to configure, and--test and so on, and the parameters followed by these configuration items are the detailed parameters of the configuration options. For example, the parameters behind--controller include the remote,ip=ipaddr,port=port number, note: Only in the form of remote front there are spaces, there is absolutely no space between the parameters. Otherwise it will be an error.
