Joint EMANICS/IRTF-NMRG Workshop on
Netflow/IPFIX Usage in Network Management

This page will not be updated anymore. The latest information on the workshop, including the slides of the presentations, can be found here. The workshop minutes can be found here.


The goal of the workshop is to exchange and discuss experiences and ideas in the usage of Netflow/IPFIX in network management.

Flow-based approaches are used in various areas of network management today, such as accounting, dependency discovery, and intrusion detection. The workshop will address these and other areas, as well as related activities such as flow collection and storage, querying, etc.

Workshop program

We want the workshop to be an opportunity for people to exchange and discuss their experiences and ideas. To structure the discussions the workshop will be organized into several discussion topics. For each discussion topic, there will be short presentations (10-15 minutes) highlighting different aspects of the topic, followed by a discussion round.
