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 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 single go WWW: https://nanomsg.org/
