Hi all,

Has anyone thought about how to access OpenFlow headers via the Python
API? I am writing a component that collects aggregate statistics from
switches. To pair up the request with the response that generated it,
I need the transaction id field from the OpenFlow headers. (Note that
without a way to do this pairing aggregate statistics are pretty much
useless!) Ideally I would be able to do the following:

  xid = send_aggregate_stats_request(...)

  def aggregate_stats_handler(xid,dpid,stats):
     ...

Is something like this is in the works or if there is another way to
achieve the same effect?

Thanks,
Nate
