| 6 | Overview |
| 7 | ^^^^^^^^ |
| 8 | |
| 9 | One of the benefits of FD.io VPP, is high performance on relatively low-power computing, this performance is based on the following features: |
| 10 | |
| 11 | * A high-performance user-space network stack designed for commodity hardware. |
| 12 | |
| 13 | - L2, L3 and L4 features and encapsulations. |
| 14 | |
| 15 | * Optimized packet interfaces supporting a multitude of use cases. |
| 16 | |
| 17 | - An integrated vhost-user backend for high speed VM-to-VM connectivity. |
| 18 | - An integrated memif container backend for high speed Container-to-Container connectivity. |
| 19 | - An integrated vhost based interface to punt packets to the Linux Kernel. |
| 20 | |
| 21 | * The same optimized code-paths run execute on the host, and inside VMs and Linux containers. |
| 22 | * Leverages best-of-breed open source driver technology: `DPDK <https://www.dpdk.org/>`_. |
| 23 | * Tested at scale; linear core scaling, tested with millions of flows and mac addresses. |
| 24 | |
| 25 | These features have been designed to take full advantage of common micro-processor optimization techniques, such as: |
| 26 | |
| 27 | * Reducing cache and TLS misses by processing packets in vectors. |
| 28 | * Realizing `IPC <https://en.wikipedia.org/wiki/Instructions_per_cycle>`_ gains with vector instructions such as: SSE, AVX and NEON. |
| 29 | * Eliminating mode switching, context switches and blocking, to always be doing useful work. |
| 30 | * Cache-lined aliged buffers for cache and memory efficiency. |
