+== NAME
+
+nng_bus - bus protocol
+
+== SYNOPSIS
+
+[source,c]
+----------
+#include <nng/protocol/bus0/bus.h>
+
+int nng_bus0_open(nng_socket *s);
+----------
+
+== DESCRIPTION
+
+The _nng_bus_ protocol provides for building mesh networks where
+every peer is connected to every other peer.  In this protocol,
+each message sent by a node is sent to every one of its directly
+connected peers.
+
+TIP: Messages are only sent to directly connected peers.  This means
+that in the event that a peer is connected indirectly, it will not
+receive messages.  When using this protocol to build mesh networks, it
+is therefore important that a _fully-connected_ mesh network be
+constructed.
+
+All message delivery in this pattern is best-effort, which means that
+peers may not receive messages. Furthermore, delivery may occur to some,
+all, or none of the directly connected peers. (Messages are not delivered
+when peer nodes are unable to receive.)  Hence, send operations will never
+block; instead if the message cannot be delivered for any reason it is
+discarded.
+
+TIP: In order to minimize the likelihood of message loss, this protocol
+should not be used for high throughput communications.  Furthermore, the
+more traffic _in aggregate_ that occurs across the topology, the more
+likely that message loss is to occur.
+
+=== Socket Operations
+
+The `nng_bus0_open()` call creates a bus socket.  This socket
+may be used to send and receive messages. Sending messages will
+attempt to deliver to each directly connected peer.
+
+=== Protocol Versions
+
+Only version 0 of this protocol is supported.  (At the time of writing,
+no other versions of this protocol have been defined.)
+
+=== Protocol Options
+
+The _nng_bus_ protocol has no protocol-specific options.
+
+=== Protocol Headers
+
+The _nng_bus_ protocol has no protocol-specific headers.
