Hybrid ICN project: VPP plugin
==============================
The hICN-plugin forwarder
## Introduction ##
A high-performance Hybrid ICN forwarder as a plugin to VPP.
The plugin provides the following functionalities:
- Fast packet processing
- Interest aggregation
- Content caching
- Forwarding strategies
## Quick Start ##
```
From the code tree root
(VPP installed with DEB pkg)
$ cd hicn-plugin
$ mkdir -p build
$ cd build
$ cmake .. -DCMAKE_INSTALL_PREFIX=/usr
$ make
$ sudo make install
(VPP source code -- build type RELEASE)
$ cd hicn-plugin
$ mkdir -p build
$ cd build
$ cmake .. -DVPP_HOME=<vpp dir>/build-root/install-vpp-native/vpp -DCMAKE_INSTALL_PREFIX=<vpp src>/build-root/install-vpp-native/vpp
$ make
$ sudo make install
(VPP source code -- build type DEBUG)
$ cd hicn-plugin
$ mkdir -p build
$ cd build
$ cmake .. -DCMAKE_BUILD_TYPE=DEBUG -DVPP_HOME=<vpp dir>/build-root/install-vpp_debug-native/vpp -DCMAKE_INSTALL_PREFIX=<vpp src>/build-root/install-vpp_debug-native/vpp
$ make
$ sudo make install
CMAKE variables:
- CMAKE_INSTALL_PREFIX -- set the install directory for the hicn-plugin. This is the common path to the lib folder containing vpp_plugins and vpp_api_test_plugins folders. Default is /usr/local.
- VPP_HOME -- set the directory containing the include and lib directories of vpp.
- HICN_API_TEST_HEADER_FILES -- set the install directory for the header files. Default is <vpp install dir>/include/vpp_plugins/hicn
```
## Using hICN plugin ##
### Platforms ###
hICN-plugin has been tested in:
- Ubuntu 16.04 LTS (x86_64)
- Ubuntu 18.04 LTS (x86_64)
- Debian Stable/Testing
- Red Hat Enterprise Linux 7
- CentOS 7
### Dependencies ###
Build dependencies:
- VPP 19.01
- DEB packages:
- vpp
- vpp-lib
- vpp-dev
- vpp-plugins
Hardware support:
- [DPDK](http://DPDK.org/) compatible nic
### Getting started ###
In order to start, the hICN plugin requires a running instance of VPP
The steps required to successfully start hICN are:
- Setup the host to run VPP
- Configure VPP to use DPDK compatible nics
- Start VPP
- Configure VPP interfaces
- Configure and start hICN
Detailed information for configuring VPP can be found at [https://wiki.fd.io/view/VPP](https://wiki.fd.io/view/VPP).
##### Setup the host for VPP #####
Hugepages must be enabled in the system
```
$ sudo sysctl -w vm.nr_hugepages=1024
```
In order to use a DPDK interface, the package vpp-dpdk-dkms must be installed in the system and the `uio` and `igb_uio` modules need to be loaded in the kernel
```
$ sudo apt install vpp-dpdk-dkms
$ sudo modprobe uio
$ sudo modprobe igb_uio
```
If the DPDK interface we want to assign to VPP is up, we must bring it down
```
$ sudo ifconfig <interface_name> down
```
##### Configure VPP #####
The file /etc/VPP/startup.conf contains a set of parameters to setup VPP at startup.
The following example sets up VPP to use a DPDK interfaces:
``` shell
unix {
nodaemon
log /tmp/vpp.log
full-coredump
}
api-trace {
on
}
api-segment {
gid vpp
}
dpdk {
dev 0000:08:00.0
}
```
Where `0000:08:00.0` must be replaced with the actual PCI address of the DPDK interface
##### Start VPP #####
VPP can be started as a process or a service:
``` shell
Start VPP as a service in Ubuntu 16.04
$ sudo systemctl start vpp
Start VPP as a process in both 16.04
$ sudo vpp -c /etc/vpp/startup.conf
```
