libnanomsg5 - 1.1.5+dfsg-1.1+b1 main

nanomsg is a socket library that provides several common
communication patterns. 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 dependencies.
.
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 one 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 one to query state of multiple applications in a single go
