ZeroMQ socket在什么情况下会掉线或无法投递消息? [英] Under what circumstances do ZeroMQ sockets drop or fail to deliver messages?

问题描述

对于每种通信类型，是否有某种规范或其他解释来描述正常情况下，您可以预期在 ZeroMQ 套接字上发送的消息不会被(所有)侦听进程接收到?

Is there some sort of a specification or other explanation that describes the normal cases where you can expect a message sent on a ZeroMQ socket to not be received by ( all ) the listening processes, for each communication type?

例如，我有一个实验程序，它基本上假设 PUB 套接字的所有订阅者都接收在该套接字上发送的所有消息(在初始化握手之后).我想了解该假设可能是错误的情况.谢谢，很抱歉，如果这已经被问到了.

For example I have an experimental program which basically assumes that all subscribers to a PUB socket receive all messages sent on that socket ( after an initialization handshake ). I would like to understand the cases where that assumption may be false. Thanks, and sorry if this has already been asked.
