组播(Multicast)是一种网络通信方式,它允许一个发送者同时向多个接收者发送数据。UDP组播(UDP Multicast)是一种无连接的网络通信方式,它使用UDP协议进行数据传输,适用于需要高效且实时传输数据的场景,如实时视频流、在线游戏等。 在Python3中,我们可以使用socket库来实现UDP组播通信。下面将演示如何在不同网段间进行UDP...

It doesn't appear to be possible to receive replies to multicast UDP messages. Server-side multicast does work, but only with a bit of extra config. Given the following (working) server code, adapted from the UDP Echo example: import asyncio import logging import socket import struct BROADCAST...
