...By running entirely in user space, it avoids kernel dependencies and can be embedded into sandboxes, virtualized environments, or custom appliances. Its architecture models NICs, link endpoints, route tables, and protocol engines as composable interfaces, enabling precise control over packet flow and easy mocking in tests. The stack implements TCP, UDP, ICMP, neighbor discovery, and common socket behaviors, including options like MSS/MTU handling and congestion control hooks. Because it’s written in a memory-safe language with extensive unit tests, it is easier to audit and evolve than many kernel-bound alternatives. netstack is frequently used as the networking core for systems that need strict isolation guarantees and deterministic behavior without privileged code.

These flow tools are written in C++ using libboost and the socket library code from Qt. They provide capabilities to capture flow-exports from Cisco routers, and write them to stdout or to a file hierarchy with rotating files.
