Abstract

In highspeed networks it becomes more and more important to monitor data and to give a possibility for accounting as well. To fulfill these tasks there exists a software named VERMONT. It can capture packets on a network interface and filter them. For analysis it exports this data as an IPFIX stream. If configured with the aggregation part in highspeed networks, VERMONT has the disadvantage, that it is yet capturing too few packets in too much time. This is due to the very flexible implementation of the aggregator. This flexibility gives it the possibility to deal with many types of input formats at the cost of performance. The main goal of this work was to optimize this part, so that it can process more packets and concurrently save CPU time. This was achieved by a reduction of the flexibility, by what it became possible to simplify computationally intensive loops. Another goal of this thesis was the expansion of the exisiting filter possibilities of VERMONT by a string filter and a regular expressions filter. This makes it possible to reduce the relevant packets scheduled for processing. To verify the modifications, some tests were conducted at the end of the work. These measurings show, that through the optimizations an increase of about 10 percent in processed packets in comparision to the old version had been achieved.
