nanomsg is a socket library that provides several common communication
patterns. It aims to make the networking layer fast, scalable, and easy
to use.
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 one go
