Existing Flow-based Measurement and Analysis Applications

  In this chapter, we will focus on existing applications for network measurement and analysis that are already using the flow concept. The concept is still quite new, so there are not yet too many of them. The most well known, since it is implemented in all newer Cisco switches is probably Ciscos ``NetFlow Data Export''. Also quite common is ``NeTraMet/NeMaC'', which is the first set of programs implementing the IETF architecture for traffic measurement. A more experimental project is NLANRs ``OC3MON''. This development is very interesting because of its hardware which allows to analyze traffic on 150 Mbit/s ATM OC3 links carrying IP traffic which is encoded on top of ATM AAL5 as described in RFC1483 [11].
