This is work in progress! Everything can change at any moment! :-)

PiCN is a...

• prototyping-friendly, modular and extensible library for content-centric networkig (CCN).
• a set of tools and network nodes.
• our platform to build the next generation of NFN.

PiCN is written in Python 3.6+ and tested on Linux, Mac OS X and Windows. More than 200 unit tests are included.

• Link Layer (UDP faces)
• Packet Encoding Layer (NDN packet format + link protocol)
• CCN Layer (basic forwarding logic, data structs)
• Chunking Layer
• Computation Layer (next-gen NFN implementation)
• Management interface to each layer

• Forwarder
• Setup Tool to start, connect, configure and inspect multiple nodes (with NDN testbed access)
• Peek Tool
• Management Tool

Let us setup a simple network which consists of a data repository and a forwarding node:

Clone PiCN from github:

you@machine:~$ git clone https://github.com/cn-uofbasel/PiCN.git

Add the PiCN-tools to your PATH (bash):

you@machine:~$ PATH=$PATH:`pwd`/PiCN/starter

or config python library:

you@machine:~$ cd PiCN && export PYTHONPATH=${PYTHONPATH}:`pwd`

Prepare content for a repository:

you@machine:~$ mkdir /tmp/repo
you@machine:~$ touch /tmp/repo/example && echo "HELLO WORLD" > /tmp/repo/example
...

Start a repository node and a forwarder:

you@machine:~$ picn-repo --format ndntlv /tmp/repo /the/prefix 10000 &
you@machine:~$ picn-relay --format ndntlv --port 9000 &  
...

Configure a forwarding rule from the forwarder to the repository:

you@machine:~$ picn-mgmt --ip 127.0.0.1 --port 9000 newface 127.0.0.1:10000:0
you@machine:~$ picn-mgmt --ip 127.0.0.1 --port 9000 newforwardingrule /the:0
...

Fetch content from the repository via the forwarding node:

you@machine:~$ picn-fetch --format ndntlv 127.0.0.1 9000 /the/prefix/example 
HELLO WORLD
