如果( 且仅当)您使用 ZMQ_PUB 或 ZMQ_SUB 套接字——在您给出的示例中您没有使用 ROUTER、XREQ 等——您可以使用 UDP,或者更准确地说, UDP 多播 通过 “epgm://主机:端口” EPGM 代表 Encapsulated PGM ,即封装在 UDP 中的 PGM ,它比原始 PGM 更兼容现有的网络基础设施。 另见http://api.zeromq...
6. 使用ZMQ进行分布式事件处理 ZMQ(ZeroMQ)是一个高性能异步消息库,适用于构建分布式系统。示例代码:...
ZeroMQ(ZMQ)是一个高性能异步消息传递库,它支持多种消息传递模式,其中之一就是Sub模式。在Sub模式下,一个或多个客户端(Subscribers)订阅了一个或多个主题(Topics),而服务器(Publisher)则将消息发布给指定的主题。 使用Python 实现 ZMQ Sub 模式 在Python中,我们可以使用pyzmq库来实现ZMQ Sub 模式。以下是一个简...
"For example:\n" "-server -sub [topic1] [...]\n" "-client -sub [topic1] [...]\n" "-server -pub [topic] [msg]\n" "-client -pun [topic] [msg]\n"); return 0; } int i=0; for(i=3; i<argc; i++) { zmq_setsockopt(subscriber, ZMQ_SUBSCRIBE, argv[i], strlen(argv...
简介: ZeroMQ并不是一个对socket的封装,不能用它去实现已有的网络协议。 它有自己的模式,不同于更底层的点对点通讯模式。 它有比tcp协议更高一级的协议。(当然ZeroMQ不一定基于TCP协议,它也可以用于进程间和进程内通讯) 它改变了通讯都基于一对一的连接这个假设。

ZeroMQ is a high-performance asynchronous messaging library, aimed at use in distributed or concurrent applications. It supports common messaging patterns (pub/sub, request/reply, client/server and others) over a variety of transports (TCP, in-process, inter-process, multicast, WebSocket and more...

Operating within a multi-threaded and multi-processor environment, DigitalPy employs thread locks within these factory containers to maintain data consistency and prevent race conditions. To disseminate updates efficiently, the framework utilizes a ZeroMQ publish-subscribe (pub/sub) mechanism. In this se...
