your debugging and retrieving various statistics. It also supports
flow entry pusher to allow users to manually insert flows into switch.

$ curl http://<controller_ip>:8080/stats/switches
- get the desc stats
$ curl http://<controller_ip>:8080/stats/desc/<dpid>
- get flows stats
$ curl http://<controller_ip>:8080/stats/flow/<dpid>
- get ports stats
$ curl http://<controller_ip>:8080/stats/port/<dpid>
- add a flow entry
$ curl -d '{"dpid": "1", "cookie":"0", "priority":"32768", \
"actions":[{"port":2, "type":"OUTPUT"}], "match":{"in_port":1}}' \

What's Ryu
Ryu is an Operating System for Software Defined Networking.
Ryu aims to provide a logically centralized control and well defined API that make it easy for operators to create new network management and control applications. Currently, Ryu manages network devices by using OpenFlow. You can say that Ryu is an OpenFlow Controller, which support OpenFlow v1.0, v1.2, and Nicira Extensions.
All of the code is freely available under the Apache 2.0 license. Ryu is fully written in Python.
Quick Start
Installing Ryu is quite easy:
% pip install ryuIf you prefer to install Ryu from the source code:
% git clone git://github.com/osrg/ryu.git
% cd ryu; python ./setup.py installIf you want to use Ryu with OpenStack, please refer detailed documents. You can create tens of thousands of isolated virtual networks without using VLAN. The Ryu application is included in OpenStack mainline as of Essex release.
If you want to write your Ryu application, have a look at Writing ryu application document. After writing your application, just type:
% ryu-manager yourapp.pySupport
