Networking

Twisted

`Twisted <http://twistedmatrix.com/trac/>`_ is an event-driven networking engine. It can be

used to build applications around many different networking protocols, including http servers

and clients, applications using SMTP, POP3, IMAP or SSH protocols, instant messaging and

`many more <http://twistedmatrix.com/trac/wiki/Documentation>`_.

PyZMQ

`PyZMQ <http://zeromq.github.com/pyzmq/>`_ is the Python binding for `ZeroMQ <http://www.zeromq.org/>`_,

which is a high-performance asynchronous messaging library. One great advantage is that ZeroMQ

can be used for message queuing without message broker. The basic patterns for this are:

- request-reply: connects a set of clients to a set of services. This is a remote procedure call

and task distribution pattern.

- publish-subscribe: connects a set of publishers to a set of subscribers. This is a data

distribution pattern.

- push-pull (or pipeline): connects nodes in a fan-out / fan-in pattern that can have multiple

steps, and loops. This is a parallel task distribution and collection pattern.

For a quick start, read the `ZeroMQ guide <http://zguide.zeromq.org/page:all>`_.

gevent

`gevent <http://www.gevent.org/>`_ is a coroutine-based Python networking library

that uses greenlets and libevent event loop.
