For example, app-A has app-X in CONTEXTS, and app-B depends on app-X as
SERVICE. When app-B is specified in the app-lists before app-A, the
instantiating app-X fails by an assertion.

What's Ryu ========== Ryu is a component-based software defined networking framework. Ryu provides software components with well defined API that make it easy for developers to create new network management and control applications. Ryu supports various protocols for managing network devices, such as OpenFlow, Netconf, OF-config, etc. About OpenFlow, Ryu supports fully 1.0, 1.2, 1.3, 1.4 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 <http://openstack.org/>`_, please refer `detailed documents <http://ryu.readthedocs.org/en/latest/using_with_openstack.html>`_. 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 <http://ryu.readthedocs.org/en/latest/writing_ryu_app.html>`_ 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 <https://lists.sourceforge.net/lists/listinfo/ryu-devel>`_. `The ML archive at Gmane <http://dir.gmane.org/gmane.network.ryu.devel>`_ is also available.
