This is a prelimnary version of DIFANE release, which contains two parts:

1. Read wildcard rules and partition them. (partition directory) NOTE: In the evaluation of our DIFANE paper, we used a tool SCAPPATT to reduce the redundancy in the rules before running the partition algorithm. The SCAPPATT tool was got from Chad R. Meiners at [email protected]

2. DIFANE implementation in Click-based OpenFlow (You have to manually take 1.'s output rules into the authority switches you select.)

• The instructions for using Click-based OpenFlow is at http://www.openflowswitch.org/wk/index.php/OpenFlowClick
• Then you need to use our code (in prototype directory) to replace the openflow directory in Click

We are still working on integrating Part 1's function in NOX, and combining Part 1 and Part 2 together to build a complete DIFANE system.
