# P4 Tutorial
|
|
|
|
## Introduction
|
|
|
|
Welcome to the P4 Tutorial!
|
|
|
|
We've prepared a set of exercises to help you get started with P4
|
|
programming, organized into four modules:
|
|
|
|
1. Introduction
|
|
* [Basic Forwarding](./basic)
|
|
* [Basic Tunneling](./basic_tunnel)
|
|
|
|
2. Monitoring and Debugging
|
|
* [Explicit Congestion Notification](./ecn)
|
|
* [Multi-Hop Route Inspection](./mri)
|
|
|
|
3. Advanced Data Structures
|
|
* [Source Routing](./source_routing)
|
|
* [Calculator](./calc)
|
|
|
|
4. Dynamic Behavior
|
|
* [Load Balancing](./load_balance)
|
|
|
|
## Obtaining required software
|
|
|
|
If you are starting this tutorial at SIGCOMM 2017, then we've already
|
|
provided you with a virtual machine that has all of the required
|
|
software installed.
|
|
|
|
Otherwise, to complete the exercises, you will need to either build a
|
|
virtual machine or install several dependencies.
|
|
|
|
To build the virtual machine:
|
|
- Install [Vagrant](https://vagrantup.com) and [VirtualBox](https://virtualbox.org)
|
|
- `cd vm`
|
|
- `vagrant up`
|
|
- Log in with username `p4` and password `p4` and issue the command `sudo shutdown -r now`
|
|
- When the machine reboots, you should have a graphical desktop machine with the required software pre-installed.
|
|
|
|
To install dependences by hand:
|
|
- `git clone https://github.com/p4lang/behavioral-model.git`
|
|
- `git clone https://github.com/p4lang/p4c`
|
|
- `git clone https://github.com/p4lang/tutorials`
|
|
Then follow the instructions for how to build each package. Each of
|
|
these repositories come with dependencies, which can be installed
|
|
using the supplied instructions. The first repository
|
|
([behavioral-model](https://github.com/p4lang/behavioral-model))
|
|
contains the P4 behavioral model. It is a C++ software switch that
|
|
will implement the functionality specified in your P4 program. The
|
|
second repository ([p4c](https://github.com/p4lang/p4c-bm)) is the
|
|
compiler for the behavioral model. It takes P4 program and produces a
|
|
JSON file which can be loaded by the behavioral model. The third
|
|
repository ([tutorial](https://github.com/p4lang/tutorial)) is the P4
|
|
Tutorial itself. You will also need to install `mininet`. On Ubuntu,
|
|
it would look like this:
|
|
|
|
```
|
|
$ sudo apt-get install mininet
|
|
```
