NN_PAIR(7)			 nanomsg 1.0.0			    NN_PAIR(7)

NAME
       nn_pair - one-to-one scalability	protocol

SYNOPSIS
       #include	<nanomsg/nn.h>

       #include	<nanomsg/pair.h>

DESCRIPTION
       Pair protocol is	the simplest and least scalable	scalability protocol.
       It allows scaling by breaking the application in	exactly	two pieces.
       For example, if a monolithic application	handles	both accounting	and
       agenda of HR department,	it can be split	into two applications
       (accounting vs. HR) that	are run	on two separate	servers. These
       applications can	then communicate via PAIR sockets.

       The downside of this protocol is	that its scaling properties are	very
       limited.	Splitting the application into two pieces allows to scale the
       two servers. To add the third server to the cluster, the	application
       has to be split once more, say by separating HR functionality into
       hiring module and salary	computation module. Whenever possible, try to
       use one of the more scalable protocols instead.

   Socket Types
       NN_PAIR
	   Socket for communication with exactly one peer. Each	party can send
	   messages at any time. If the	peer is	not available or send buffer
	   is full subsequent calls to nn_send(3) will block until it's
	   possible to send the	message.

   Socket Options
       No protocol-specific socket options are defined at the moment.
