py-unsserv: P2P out-of-the-box

py-unsserv is high-level Python library, designed to offer out-of-the-box peer-to-peer (p2p) network, as well as a bunch of functionalities on top of it. These functionalities include:

  • Membership (or p2p network creation)
  • Clustering
  • Metrics aggregation
  • Nodes sampling
  • Dissemination (or broadcasting)
  • Data searching (key-value caching oriented)

Look how easy it is to setup a P2P network and broadcast some data:

import asyncio
from typing import Tuple

from unsserv import join_network, get_dissemination_service

Host = Tuple[str, int]

async def broadcaster(host: Host):
    # join p2p network
    membership = await join_network(host, "")
    # initialize dissemination service
    dissemination = await get_dissemination_service(membership, "")
    # wait for receiver to join network
    await asyncio.sleep(1)
    # broadcast data
    for _ in range(10):
        await dissemination.broadcast(b"data.alert")
        await asyncio.sleep(1)

async def receiver(host: Host, broadcaster_host: Host):
    # wait for broadcaster to join network
    await asyncio.sleep(1)
    # join p2p network
    membership = await join_network(
        host, "", bootstrap_nodes=[broadcaster_host]
    # initialize dissemination service and add broadcast handler

    async def handler(data: bytes):

    await get_dissemination_service(
        membership, "", broadcast_handler=handler
    # wait for broadcast
    await asyncio.sleep(10)

if __name__ == "__main__":
    broadcaster_host = ("", 7771)
    receiver_host = ("", 7772)

    loop = asyncio.new_event_loop()
    loop.create_task(receiver(receiver_host, broadcaster_host=broadcaster_host))


To install py-unsserv, you just need to run the following command on your terminal:

$ pip install unsserv
