async_multiplexer is a TCP Multiplexer based on Mplex protocol, but simplified. It is intended for creating mutiple streams in parallel on top of a same TCP connection.

Installation

pip install async-multiplexer

Usage

Client

import asyncio
from async_multiplexer import open_multiplexer_context

async def echo_client():
    async with open_multiplexer_context("127.0.0.1", 7777) as multiplexer:
        stream_echo_1 = await multiplexer.multiplex("echo.1")
        stream_echo_2 = await multiplexer.multiplex("echo.2")
        await stream_echo_1.write(b"echo.1")
        await stream_echo_2.write(b"echo.2")


if __name__ == "__main__":
    asyncio.run(echo_client())

Server

import asyncio
from async_multiplexer import bind_multiplex_listener_context

async def handler(stream):
    data = await stream.read()
    print(data)

async def echo_server():
    async with bind_multiplex_listener_context("127.0.0.1", 7777) as listener:
        listener.set_handler("echo.1", handler)
        listener.set_handler("echo.2", handler)
        await asyncio.sleep(10)

if __name__ == "__main__":
    asyncio.run(echo_server())
