Here's my POX fork that does enough OpenFlow 1.1 to pass a basic unit test with an MPLS packet https://github.com/samrussell/pox/tree/of11
It breaks wildcarding in the process, and the rest of the spec needs to be implemented to make it work properly (e.g. pack/unpack fails on most classes, probably due to the new 32-bit ports), as well as other messages, but my goal here is just to get it up and running so that there's a python controller that speaks OpenFlow 1.1 Here's the main functionality that I'm aiming for: - Can auto-generate matches based on compatible packets (done) - Implements actions for MPLS stuff This should really be all that it needs for it to be integrated into a label-switched router. The rest will come, as well as ways to make the 1.0/1.1 split more pretty, but I'm really after a reference MPLS spec in POX. I've found some other stuff on the way: - the mpls class stores its payload as raw data rather than parsing it as IP(v4) - the wildcarding is heavily tied to fields that can be matched - new IP and ethernet masks will either need more special cases like IP currently has in 1.0, or a new approach to wildcarding
