An advantage of flow-based measurement is that it allows monitoring large amounts of traffic observed at distributed Observation Points. While flow-based measurement can be applied to one of various purposes and applications, it is difficult for flow-based measurement to apply to multiple applications with very different requirements in parallel. Network administrators need to adjust the parameters of the metering devices to fulfill the requirements of every single measurement application. Such configurations are often not supported by the metering devices, either because of functional restrictions or because of limited computational and memory resources, which inhibit the metering of large amounts of traffic with the desired setup. IP Flow Information Export (IPFIX) Mediation fills the gap between restricted metering capabilities and the requirements of measurement applications by introducing an intermediate device called the IPFIX Mediator.

     IP Flow Information Export (IPFIX) Mediation: Problem Statement


   Flow-based measurement is a popular method for various network    monitoring usages.  The sharing of flow-based information for    monitoring applications having different requirements raises some    open issues in terms of measurement system scalability, flow-based    measurement flexibility, and export reliability that IP Flow    Information Export (IPFIX) Mediation may help resolve.  This document    describes some problems related to flow-based measurement that    network administrators have been facing, and then it describes IPFIX    Mediation applicability examples along with the problems.
