== About Nanomsg
NOTE: The latest release of nanomsg is {{ site.latest }}.
*_nanomsg_* is a is a socket library that provides several common communication
It aims to make the networking layer fast, scalable, and easy to use.
Implemented in C, it works on a wide range of operating systems with no further
The communication patterns, also called "scalability protocols", are basic
blocks for building distributed systems.
By combining them you can create a vast array of distributed applications.
The following scalability protocols are currently available:
* PAIR - simple one-to-one communication
* BUS - simple many-to-many communication
* REQREP - allows to build clusters of stateless services to process user requests
* PUBSUB - distributes messages to large sets of interested subscribers
* PIPELINE - aggregates messages from multiple sources and load balances them among many destinations
* SURVEY - allows to query state of multiple applications in a single go
Scalability protocols are layered on top of the transport layer in the network
At the moment, the _nanomsg_ library supports the following transports
* INPROC - transport within a process (between threads, modules etc.)
* IPC - transport between processes on a single machine
* TCP - network transport via TCP
* WS - websockets over TCP
The library exposes a BSD-socket-like C API to the applications.
