| Description | This demo demonstrates results of a joint research project of CESNET and INVEA-TECH focused on 100 GbE network flow monitoring using FPGA. It shows, to the best of our knowledge, the first flow monitoring setup capable of handling fully saturated 100 G Ethernet line. We present COMBO-CG card that provides accurate timestamps for high-resolution traffic monitoring. The card is complemented by fast DMA engine and optimized Linux drivers which were designed and implemented to achieve 100 Gbps data transfers through PCIe bus with low CPU utilization. Network traffic can be distributed among multiple CPU cores based on configurable hash functions. Our flow exporter is able to fully utilize available CPU cores to provide wire-speed performance for processing of the 100 Gbps traffic. The demo will show complete 100 G flow monitoring setup – from packet generator to flow collector |
