| NAME |
| ---- |
| nn_bus - message bus scalability protocol |
| |
| |
| SYNOPSIS |
| -------- |
| *#include <nanomsg/nn.h>* |
| |
| *#include <nanomsg/bus.h>* |
| |
| |
| DESCRIPTION |
| ----------- |
| Broadcasts messages from any node to all other nodes in the topology. The socket |
| should never receives messages that it sent itself. |
| |
| This pattern scales only to local level (within a single machine or within |
| a single LAN). Trying to scale it further can result in overloading individual |
| nodes with messages. |
| |
| WARNING: For bus topology to function correctly, user is responsible for |
| ensuring that path from each node to any other node exists within the topology. |
| |
| Raw (AF_SP_RAW) BUS socket never sends the message to the peer it was received |
| from. |
| |
| Socket Types |
| ~~~~~~~~~~~~ |
| |
| NN_BUS:: |
| Sent messages are distributed to all nodes in the topology. Incoming |
| messages from all other nodes in the topology are fair-queued in the |
| socket. |
| |
| Socket Options |
| ~~~~~~~~~~~~~~ |
| |
| There are no options defined at the moment. |
