The extension may be required on two fields:
1- Defining the flow
2- Available actions
For defining the flow, an update may not be required, specially at first
version of the library.
But for action, there may be some updates.
IPFIX RFC defines Metering process as [1], (in [2]). This library should
provide helper APIs to metering process.
Currently only action can be used in rte_flow is COUNT, more actions can
be added to help "packet header capturing, timestamping, sampling,
classifying" tasks of the metering process.
The exact list depends on the what will be implemented in this release.
[1]
Metering Process
The Metering Process generates Flow Records. Inputs to the
process are packet headers, characteristics, and Packet Treatment
observed at one or more Observation Points.
The Metering Process consists of a set of functions that includes
packet header capturing, timestamping, sampling, classifying, and
maintaining Flow Records.
The maintenance of Flow Records may include creating new records,
updating existing ones, computing Flow statistics, deriving
further Flow properties, detecting Flow expiration, passing Flow
Records to the Exporting Process, and deleting Flow Records.
