在多播套接字上接收单播 [英] Receiving Unicast on Multicast socket

问题描述

我有一台服务器向 192.168.1.101 端口 55555 发送单播 UDP 数据包.

I have a server sending unicast UDP packets to 192.168.1.101, port 55555.

我的 Android 设备的 IP 为 192.168.1.101.我的 Android 设备有一个绑定在端口 55555 上的多播套接字加入了多播组 230.1.1.111.

My Android device has IP 192.168.1.101. My Android device has a multicast socket bound on port 55555 joined on multicast group 230.1.1.111.

我在 Android 的多播套接字上从服务器接收数据报.

I am receiving datagrams on my Android's multicast socket from the server.

这有意义吗?多播套接字可以接收不是寻址到它加入的多播组的数据报吗?

Does this make sense? Can a multicast socket receive datagrams which are not addressed to the multicast group it's joined?

推荐答案

多播套接字是否可以接收未寻址到其加入的多播组的数据报?

Can a multicast socket receive datagrams which are not addressed to the multicast group it's joined?

是的，可以.它可以加入零个或多个多播组.这不会影响其单播功能.

Yes it can. It can join zero or more multicast groups. That doesn't affect its unicast capabilities.
