NAME

6       nn_bus - message bus scalability protocol
7

SYNOPSIS

9       #include <nanomsg/nn.h>
10
11       #include <nanomsg/bus.h>
12

DESCRIPTION

14       Broadcasts messages from any node to all other nodes in the topology.
15       The socket should never receive messages that it sent itself.
16
17       This pattern scales only to local level (within a single machine or
18       within a single LAN). Trying to scale it further can result in
19       overloading individual nodes with messages.
20
21           Warning
22           For bus topology to function correctly, user is responsible for
23           ensuring that path from each node to any other node exists within
24           the topology.
25
26       Raw (AF_SP_RAW) BUS socket never sends the message to the peer it was
27       received from.
28
29   Socket Types
30       NN_BUS
31           Sent messages are distributed to all nodes in the topology.
32           Incoming messages from all other nodes in the topology are
33           fair-queued in the socket.
34
35   Socket Options
36       There are no options defined at the moment.
