Vector Packet Processing (VPP) platform is an extensible, open-source framework, which offers the functionality of network switches or routers. V''ector processing'' is the process of processing multiple packets at a time, with low latency. Single packet processing and high latency are present in the ''scalar processing'' approach, which VPP aims to make obsolete.
This open-source,
Linux Foundation backed framework is part of the '
Fast Data Project'' (FD.io)

The Data Plane Development Kit (DPDK) is an open source software project managed by the Linux Foundation. It provides a set of data plane libraries and network interface controller polling-mode drivers for offloading TCP packet processing f ...
device drivers and libraries for many of its layer 1 functions - however, this functionality is separated into an optional plugin-in for VPP.
Technology
In order to push for scalability of networks, VPP reads the largest available sector of packets in the networks
I/O layer. Instead of processing each packet individually throughout an entire graph with several
nodes
In general, a node is a localized swelling (a "knot") or a point of intersection (a Vertex (graph theory), vertex).
Node may refer to:
In mathematics
*Vertex (graph theory), a vertex in a mathematical graph
*Vertex (geometry), a point where two ...
, VPP selects the entire vector of packets and pushes them through a graph node, before moving on to the next node. The instruction
cache
Cache, caching, or caché may refer to:
Places United States
* Cache, Idaho, an unincorporated community
* Cache, Illinois, an unincorporated community
* Cache, Oklahoma, a city in Comanche County
* Cache, Utah, Cache County, Utah
* Cache County ...
then adapts to the process and the remaining packets are processed even faster, due to the previously learned instructions from the first vector packet.
