It has + identified itself as "Quantum." It aims to tame your (cloud) networking! + +# -- Basics: + +1) Quantum REST API: Quantum supports a REST-ful programmatic interface to + manage your cloud networking fabric. + +2) Quantum Plugins: Quantum sports a plug-able architecture that allows + Quantum's REST API to be backed by various entities that can create a + cloud-class virtual networking fabric. The advantages of this plug-able + architecture is two-folds: + + a) Allows for ANY open-source project or commercial vendor to write a + Quantum plug-in. + + b) Allows Quantum users to not be tied down to a single Quantum + implementation and enables them to switch out a plug-in by simple editing a + config file - plugins.ini + +# -- Dependencies + + The following python packages are required to run quantum. These can be + installed using pip: + + eventlet>=0.9.12 + nose + Paste + PasteDeploy + pep8==0.5.0 + python-gflags + routes + simplejson + webob + webtest + +1) Install easy_install (there is probably a distribution specific package for +this) + +2) Install pip: + $ easy_install pip==dev +3) Install packages with pip: + $ pip install + +# -- Configuring Quantum plug-in + +1) Identify your desired plug-in. Choose a plugin from one of he options in + the quantum/plugins directory. + +2) Update plug-in configuration by editing the quantum/plugins.ini file and + modify "provider" property to point to the location of the Quantum plug-in. + It should specify the class path to the plugin and the class name (i.e. for + a plugin class MyPlugin in quantum/plugins/myplugin/myplugin.py the + provider would be: quantum.plugins.myplugin.myplugin.MyPlugin) + +3) Read the plugin specific README, this is usually found in the same + directory as your Quantum plug-in, and follow configuration instructions. + +# -- Launching the Quantum Service + +1) Start quantum using the following command [on the quantum service host]: +~/src/quantum$ PYTHONPATH=.:$PYTHONPATH python bin/quantum etc/quantum.conf + +# -- Making requests against the Quantum Service + +Please refer to sample Web Service client code in: + +../quantum/test_scripts/miniclient.py + +# -- CLI tools to program the Quantum-managed Cloud networking fabric + +Quantum comes with a programmatic CLI that is driven by the Quantum Web +Service.
