Isaku Yamahata 3ac48b77e1 gre_tunnel: exception due to race condition 
This depends on thread scheduling.
When event handler is invoked, there may not corresponding network_id in
network module.
In fact, Network.remove_network() fires EventNetworkPort(add_del=False)
before EventNetworkDel event so that it is unnecessary to call
_vm_port_mac_handler().

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, v1.3, 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 ryu

If you prefer to install Ryu from the source code:

% git clone git://github.com/osrg/ryu.git
% cd ryu; python ./setup.py install

If 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.py

Support

Ryu Official site is http://osrg.github.io/ryu/.

If you have any questions, suggestions, and patches, the mailing list is available at ryu-devel ML. The ML archive at Gmane is also available.
