Scott Keelerd9668e72018-09-06 07:52:59 -0400[diff] [blame]9One of the benefits of FD.io VPP is high performance on relatively low-power computing, this performance is based on the following features:
John DeNisco06dcd452018-07-26 12:45:10 -0400[diff] [blame]10
Scott Keelerd9668e72018-09-06 07:52:59 -0400[diff] [blame]11* A high-performance user-space network stack designed for commodity hardware:
John DeNisco06dcd452018-07-26 12:45:10 -0400[diff] [blame]12
13 - L2, L3 and L4 features and encapsulations.

Scott Keelerd9668e72018-09-06 07:52:59 -0400[diff] [blame]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

Scott Keelerd9668e72018-09-06 07:52:59 -0400[diff] [blame]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

25These features have been designed to take full advantage of common micro-processor optimization techniques, such as:
26
Scott Keelerd9668e72018-09-06 07:52:59 -0400[diff] [blame]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
