NOX 1.3 Oflib ------------- Attention! ----------- The controller is still under development and needs changes to support all OpenFlow 1.3 features and also to conform with previous messages that were modified in the new version. Despite the fact that an easier API is available, still it's possible to send new messages using the the oflib, present on this NOX version. The controller connects to the datapath without problems and an example application What is missing so far? - Multiple connections support - Some messages changed in OpenFlow 1.3 (e.g ofp_features_request do not carry port stats anymore). We need to look better how this affects the controller (This may mean lots of redesigning...). Important!! OpenFlow 1.3 changed the default behavior of the tables on a Table-Miss. Now packets are dropped and not of sent to the controller like it was on previous versions. So, if it isn't what you want to your application, install a flow with low priority to define your default. This is an OpenFlow 1.3 [1] compatible version of the NOX controller. The code is based on Nicira's NOX Zaku controller [2], with OpenFlow proecessing being replaced with Oflib from the OpenFlow 1.3 Software Switch [3]. The controller only supports C++ applications (no Python).

To compile it in a later version you should downgrade almost every dependency, so we recommend, while the code isn't updated, to use an older system version. Getting Started --------------- To build, run the following commands in the of11softswitch directory: ./boot.sh mkdir build cd build ../configure --with-python=no make To start the controller, run the following commands: cd build/src ./nox-core -i ptcp:<port> [applications] This will start the controller, listening on the given port for switch connetions. For a complete list of options, use the --help argument. Contribute ---------- Please submit your bug reports, fixes and suggestions as pull requests on github, or by contacting us directly.
