The project aims to create a device to process and filter traffic on high-speed networks (up to 400 Gbps) with HW and SW support for application analysis of packets. The device will feature modular design allowing to add support for specific application protocols (as plug-ins). Hardware-accelerated network cards will be used to achieve high processing performance. Accelerators will provide Ethernet interface with total throughput of 400 Gbps in both directions. The software layer will be prepared to collaborate with common network adaptors with lower performance but affordable price.
