Banyan

Banyan is a simple peer to peer application protocol

Installation

pip install banyancli

What can it do currently?

• File Sharing over LAN

How it works?

The workflow is organized as follows

1. Initialization - Peer Starts up with a friendly name, which is visible on local network
2. Peer Discovery - Peer Sends a broadcast to all other hosts in local network. Other peers will respond to it.
3. Synchronization - Peer Receives file list from all other Peers
4. Transfer - Peer can receive file from any other Peer

Requirements

• Python 3.6 or later
• Couple of machines to work with and test
