The NDN State Vector Sync (SVS) Protocol in Python 3

ndn-python-svs: State Vector Sync NDN Python library

This python library implements the State Vector Sync (SVS) protocol to synchronise states between multiple clients over NDN for distributed realtime applications.

This is an official implementation but considered 'experimental'. If there are any concerns or suggestions, please create a new issue.

ndn-python-svs uses the python-ndn library for it's implementation.

Installation

Prerequisites

• python-ndn

• nfd

• pip if downloading via python pip

From Pip

Download the python pip library ndn-svs

From Source

Clone or Fork the github repository ndn-python-svs

Examples

To try out the chat demo application from source, follow the below steps.

To create a chat client, simply run this in the home directory of the repo:

python3 examples/chat_node.py -n NODE_NAME [-gp GROUP_PREFIX] [-h]

You may create as many of these as possible and all clients will sync up using SVS.

For All Usage

Before you run the program, you must register the group prefix as multi-cast (even if you did not specifically define the group prefix):

nfdc strategy set <group-prefix> /localhost/nfd/strategy/multicast/%FD%03

The default (unless specified) group prefix is /svs for any build-in examples.

More on setting different strategies (like mutli-cast) for prefixes.
