.. _network-stack: ====================== Network Stack Features ====================== This section describes a little about the FD.io network stack and describes some benefits: * Layer 2 - 4 Network Stack * Fast lookup tables for routes, bridge entries * Arbitrary n-tuple classifiers * Control Plane, Traffic Management and Overlays * `Linux `_ and `FreeBSD `_ support * Support for standard Operating System Interfaces such as AF_Packet, Tun/Tap & Netmap. * Network and cryptographic hardware support with `DPDK `_. * Container and Virtualization support * Para-virtualized interfaces; Vhost and Virtio * Network Adapters over PCI passthrough * Native container interfaces; MemIF * Host Stack * Universal Data Plane: one code base, for many use cases * Discrete appliances; such as `Routers `_ and `Switches `_. * `Cloud Infrastructure and Virtual Network Functions `_ * `Cloud Native Infrastructure `_ * The same binary package for all use cases. * Out of the box production quality, with thanks to `CSIT `_.
