This may need to be addressed in the framework. This proposes an improved interface for managing RTFM meters, making it easier to use them in network operations. The current RTFM meter control and data-gathering interfaces are not clearly distinguished. This could be improved. The RTFM architecture would be improved if it included the ability to push flow data.
Many vendors have proprietary strategies for flow collection and analysis.
A new high-level interface should allow for more general flow collection mechanisms. This needs to be better explained. Georg Carle briefly presented his draft on Packet Capture Extensions, which proposes more efficient filtering and packaging of remotely captured packets before they are transmitted to the metering point. Both speakers emphasised the need to address privacy concerns. In particular, the disclosure of user is addressed by both proposals, together with the need to authenticate and authorise access to captured data.
