Hello,
I'm in the process of integrating more fine grained statistics into the
userspace implementation of openflow (udatapath).
As a simple example i want to query a switch for the data rates of each
individual flow. Estimating the rates for each flow is simple to do; the
more sophisticated part seems to be the extension of the openflow
protocol to include such a query for data rates.
In the implementation (include/openflow/openflow-ext.h) i found a
natural point to include new messages into openflow.
Now my question is: is this the right point to start from? Or do i have
to look for the "Vendor Statistics" which are mentioned in the OpenFlow
1.0 specification?
Is there any tutorial or information out there to extent the udatapath
implementation?
Regards,
Philip
