Type: test
This application creates two memif interfaces which connect
to an external application i.e. VPP.
Usage:
1) Start VPP with following config.
create interface memif id 0 master
create interface memif id 1 master
set int state memif0/0 up
set int state memif0/1 up
create packet-generator interface pg0
set int state pg0 up
create packet-generator interface pg1
set int state pg1 up
set int l2 xconn pg0 memif0/0
set int l2 xconn memif0/0 pg0
set int l2 xconn pg1 memif0/1
set int l2 xconn memif0/1 pg1
packet-generator new { \
name memif \
limit -1 \
node ethernet-input \
size 64-64 \
interface pg0 \
worker 0 \
data { \
IP4: 42:01:0a:00:00:0a -> 02:fe:4b:6e:4d:c1 \
UDP: 172.16.2.2 -> 172.16.0.2 \
UDP: 1234 -> 1234 \
length 30 checksum 0 incrementing 1 \
} \
}
2) Compile and Run the test_app in another terminal.
mkdir -p extras/libmemif/build
cd extras/libmemif/build
cmake ..
make
sudo ./examples/test_app
3) Run in VPP cli
vpp# packet enable
4) Run monitor to see the throughput and pps
vpp# monitor interface memif0/0
Or
vpp# monitor interface memif0/1

Vector Packet Processing
Introduction
The VPP platform is an extensible framework that provides out-of-the-box production quality switch/router functionality. It is the open source version of Cisco's Vector Packet Processing (VPP) technology: a high performance, packet-processing stack that can run on commodity CPUs.
The benefits of this implementation of VPP are its high performance, proven technology, its modularity and flexibility, and rich feature set.
For more information on VPP and its features please visit the FD.io website and What is VPP? pages.
Changes
Details of the changes leading up to this version of VPP can be found under doc/releasenotes.

Getting started
In general anyone interested in building, developing or running VPP should consult the VPP wiki for more complete documentation.
In particular, readers are recommended to take a look at [Pulling, Building, Running, Hacking, Pushing](https://wiki.fd.io/view/VPP/Pulling,_Building,_Run ning,_Hacking_and_Pushing_VPP_Code) which provides extensive step-by-step coverage of the topic.
For the impatient, some salient information is distilled below.
Quick-start: On an existing Linux host
To install system dependencies, build VPP and then install it, simply run the
build script. This should be performed a non-privileged user with sudo
access from the project base directory:
./extras/vagrant/build.sh
If you want a more fine-grained approach because you intend to do some
development work, the Makefile in the root directory of the source tree
provides several convenience shortcuts as make targets that may be of
interest. To see the available targets run:
make
Quick-start: Vagrant
The directory extras/vagrant contains a VagrantFile and supporting
scripts to bootstrap a working VPP inside a Vagrant-managed Virtual Machine.
This VM can then be used to test concepts with VPP or as a development
platform to extend VPP. Some obvious caveats apply when using a VM for VPP
since its performance will never match that of bare metal; if your work is
timing or performance sensitive, consider using bare metal in addition or
instead of the VM.
For this to work you will need a working installation of Vagrant. Instructions for this can be found [on the Setting up Vagrant wiki page] (https://wiki.fd.io/view/DEV/Setting_Up_Vagrant).
More information
Several modules provide documentation, see @subpage user_doc for more end-user-oriented information. Also see @subpage dev_doc for developer notes.
Visit the VPP wiki for details on more advanced building strategies and other development notes.
