ZeroMQ: Modern & Fast Networking Stack – igvita.com

Berkeley Sockets (BSD) are the de facto API for all network communication. With roots from the early 1980’s, it is the original implementation of the TCP/IP suite, and arguably one of the most widely supported and critical components of any operating system today. BSD sockets that most of us are familiar with are peer-to-peer connections, which require explicit setup, teardown, choice of transport (TCP, UDP), error handling, and so on. And once you solve all of the above, then you are into the world of application protocols (ex: HTTP), which require additional framing, buffering and processing logic. In other words, it is no wonder that a high-performance network application is anything but trivial to write.

Wouldn’t it be nice if we could abstract some of the low-level details of different socket types, connection handling, framing, or even routing? This is exactly where the ZeroMQ (ØMQ/ZMQ) networking library comes in: “it gives you sockets that carry whole messages across various transports like inproc, IPC, TCP, and multicast; you can connect sockets N-to-N with patterns like fanout, pubsub, task distribution, and request-reply”. That’s a lot buzzwords, so lets dissect some of these concepts in more detail.

Well written post about ZeroMQ. Lead to some interesting links about RabbitMQ, ActiveMQ the AMQ protocol, ICE (Internet Communications Engine) from ZeroC.

  1. After working with Node.js and WebSockets, and taking a look at the source, socket level applications don’t seem easy at all. Learning about them is fun, but I doubt writing the applications the we use on an everyday basis like curl or ftp would be a trivial task by any means. Raise a glass to ancient C developers.
