Provides the entire Linux kernel network stack as a linkable library, enabling applications to use mature, production-ready protocols without kernel modifications, as highlighted for OS personalization and testing.

Seamlessly integrates with high-speed packet I/O mechanisms like Intel DPDK and netmap, offering a full-featured stack for performance-critical applications, per the key features.

Facilitates complex network stack testing in isolated environments and integrates with simulators like ns-3 via DCE, allowing real Linux protocol execution for accurate research.

Enables per-application isolated network stacks, providing instant virtualization apart from the host OS, useful for containerized or microservices architectures.
