Monitoring at the flow level is crucial to ensure the correct operation of networks. Any sizable network relies on a number of monitoring probes, both to provide different observation points but also to scale to the ever-increasing number of flows that go through it. This situation gives rise to the difficult problem of assigning monitoring of flows to the available probes so that the network-wide...
Distributed network analysis deals with the inspection of traffic observed at various locations in the network. The conventional approach is to deploy a full-fledged network analyzer at every observation point, which allows exhaustive examinations, but at the same time is a very costly solution. In this paper, we present an alternative approach using packet data exported by PSAMP and Flexible Netflow...
Traffic monitoring is an increasingly important discipline for nowadays networking, as Accounting, Security and Traffic Engineering lay on it. Besides, traffic bandwidth has increased exponentially in the last few years, and high-speed network monitoring has become a challenging task. Performance requirements are highly relevant for passive QoS monitoring systems. A low-level study of the capturing...
