ØMQ looks like an embeddable networking library but acts like a concurrency framework. 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.

Example¶ ↑

require "zmq"

context = ZMQ::Context.new(1)

puts "Opening connection for READ"
inbound = context.socket(ZMQ::UPSTREAM)
inbound.bind("tcp://127.0.0.1:9000")

outbound = context.socket(ZMQ::DOWNSTREAM)
outbound.connect("tcp://127.0.0.1:9000")
p outbound.send("Hello World!")
p outbound.send("QUIT")

loop do
  data = inbound.recv
  p data
  break if data == "QUIT"
end
