Dear all, I am interested in extending Openvswitch to be able to match on GTP-U fields, typically used in mobile telecom networks. At a high level what I would like to do is:
1) Have an openflow controller install rules in OVS where the match portion of the rules includes fields of the GTP-U header. GTP-U runs over UDP and contains typical tunnel parameters like a tunnel ID or the endpoint IP address. I am aware that I will need to modify the Openflow implementation on the controller side as well. 2) I do not need to modify anything on the GTP-U header, so no GTP support is required regarding Openflow actions. I would appreciate if anyone can give me a high level orientation on the best design approach to accomplish the above. For example should I define the new header parameters in the ofp11_match structure and try to replicate the code existing to match other parameters (e.g. in lib/match.c), or is there an established framework in OVS to define new match types?
