Accelerated Network Technologies Research GroupANT@FIT research group was formed in September 2009 by group of researches ad PhD students at Faculty of Information Technology, Brno University of Technology. The research group deals with acceleration of time critical operations, which are used in devices for network infrastructure or devices for network monitoring and security. Network traffic processing speed is crucial in most of the network devices, because any packet drop can lead to lower quality of network services, affect precise monitoring or disallow intrusion detection and prevention. Nowadays solutions are either expensive or provide only limited performance. Therefore research group focuses on novel algorithms and architectures, which allow construction of devices and applications with higher throughput at lower price. We use standard processors, MultiCORES and FPGA technology and concentrate on packet header analysis and extraction, classification of packets, longest prefix match, pattern matching and flow CACHE management.
The research group also deals with design of devices and systems for network infrastructure, security and monitoring. In this area, we cooperate mainly with CESNET and Liberouter project and focus on system for high speed networks based on computer and acceleration cards, but we also design small size embedded systems with low power consumption and price.
Principal researcher of the team is Jan Korenek, who is a researcher at Brno University of Technology since 2003, leader of hardware design group at Liberouter project since 2004 and is one of the founders of successful spin-off INVEA-TECH. The team members have substantial experience in the network field, which was obtained by working on a number of European projects (including 6NET (IST-2001-32603), SCAMPI (IST-2001-32404), GEANT2 (No. 511082)) and on a number of locally funded projects (CESNET (MSM6383917201) and VUT (MSM002163528)). In these projects, FPGA technology was used for an acceleration of IPv6 protocol routing, network traffic monitoring, NetFlow statistic measurement and fast regular expression matching in packet payload. Network devices and probes are hardware accelerated using FPGA technology, therefore the probes can provide precise and detailed information about the network no matter of 1Gbps, 10Gbps and higher speed.
