Network monitoring is a major building block for many domains in communication networks. Besides typical accounting mechanisms and the emerging area of charging in next generation networks, especially network security solutions rely on efﬁcient and optimized monitoring. Network monitoring in high-speed networks is usually based on ﬂow accounting and aggregation techniques represent a necessary enhancement in order to cope with increasing amounts of monitoring data that accrue with the ever-growing network capacities. In this paper, we propose a ﬂexible ﬂow aggregation mechanism that can be directly employed on a monitoring probe to reduce the memory and processing demands. Alternatively, it can work as a concentrator that collects ﬂow data from multiple monitoring probes, combines and aggregates them and forwards the results to an analyzer. We veriﬁed and evaluated the aggregation mechanism by integrating it into our monitoring probe Vermont. Our approach opens new prospec...
