py-unsserv
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 use:
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, "network.id")
# initialize dissemination service
dissemination = await get_dissemination_service(membership, "dissemination.id")
# 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, "network.id", bootstrap_nodes=[broadcaster_host])
# initialize dissemination service and add broadcast handler
async def handler(data: bytes):
print(data)
await get_dissemination_service(membership, "dissemination.id", broadcast_handler=handler)
# wait for broadcast
await asyncio.sleep(10)
if __name__ == "__main__":
broadcaster_host = ("127.0.0.1", 7771)
receiver_host = ("127.0.0.1", 7772)
loop = asyncio.new_event_loop()
loop.create_task(broadcaster(broadcaster_host))
loop.create_task(receiver(receiver_host, broadcaster_host=broadcaster_host))
loop.run_forever()Installation
