Napatech Link-Inline™ Software is a software layer designed to run on Napatech FPGA-based SmartNICs, providing hardware-accelerated offload and processing for network and security applications. The software enables stateful, flow-aware processing by allowing applications running in software to dynamically and programmatically update processing actions in SmartNIC hardware on a per-flow basis. It supports inline, packet capture, and tap operating modes, and is compatible with both open-source and custom networking/security applications. Key performance characteristics: - Up to 200 Gbps throughput - Greater than 100 million concurrent flow table entries - Over 2 million flow setups and teardowns per second - Low-latency packet processing The solution reduces CPU utilization by offloading dataplane processing to the SmartNIC hardware, returning CPU resources to host applications and services. Applications interact with the SmartNIC via simple rules or standards-based APIs. Use cases include cybersecurity processing and 5G telecom user plane traffic handling. The architecture supports configurable packet classification, match fields, load balancing to application instances, and extensive per-flow actions. It is designed for deployment in standard servers, targeting organizations that require higher throughput and lower latency than general-purpose NICs can provide.
