NAME
|
||||
----
|
||||
zmq_deviced - start built-in 0MQ devices
|
||||
|
||||
SYNOPSIS
|
||||
--------
|
||||
|
||||
*zmq_deviced _DEVICE_ _FRONTEND_ _BACKEND_*
|
||||
|
||||
*zmq_deviced [_CONFIGFILE_]*
|
||||
|
||||
DESCRIPTION
|
||||
-----------
|
||||
Starts one or more 0MQ devices. If you specify a DEVICE, FRONTEND, and BACKEND
|
||||
then _zmq_device_ starts a single device acting as a mini-broker. If you
|
||||
specify a CONFIGFILE, you can configure _zmq_device_ to start multiple
|
||||
concurrent devices with arbitrary configurations.
|
||||
|
||||
*Note* - zmq_deviced is not yet implemented. This is a design.
|
||||
|
||||
MINI-BROKER USAGE
|
||||
-----------------
|
||||
Runs as a mini-broker that accepts connects to both frontend and backend. This
|
||||
creates a hub-and-spoke topology in which all peers connect to the device. This
|
||||
is a robust and easy to manage topology.
|
||||
|
||||
DEVICE is one of: *queue*, *forwarder*, or *streamer*. See
|
||||
linkzmq:zmq_device[3] for a specification of these device types.
|
||||
|
||||
FRONTEND and BACKEND are endpoints in the format 'transport'`://`'address', See
|
||||
linkzmq:zmq_bind[3] for a specification of valid transports and addresses.
|
||||
|
||||
|
||||
CONFIGURED USAGE
|
||||
----------------
|
||||
CONFIGFILE is the name of an XML file, readable by 'zmq_device'. This file
|
||||
provides a specification of the devices to start and how to connect and/or bind
|
||||
their frontends and backends. If CONFIGFILE is absent or *-* then the
|
||||
configuration is read from standard input.
|
||||
|
||||
The configuration file has this general syntax:
|
||||
|
||||
----
|
||||
<?xml?>
|
||||
<config [ iothreads="..." ] >
|
||||
<device type="...">
|
||||
<frontend [ type="..." ] >
|
||||
<set name = "..." value = "..." />...
|
||||
<bind endpoint="..." /> ...
|
||||
<connect address="..." /> ...
|
||||
</frontend>
|
||||
<backend [ type="..." ] >
|
||||
<set name = "..." value = "..." />...
|
||||
<bind address="..." /> ...
|
||||
<connect address="..." /> ...
|
||||
</backend>
|
||||
</device>
|
||||
</config>
|
||||
----
|
||||
|
||||
*iothreads*::
|
||||
specifies the number of I/O threads for the process. Specify this only for
|
||||
high-volume scenarios. See linkzmq:zmq_init[3].
|
||||
*device*::
|
||||
defines one device. For each device element you define, 'zmq_device' will
|
||||
start a thread.
|
||||
*frontend*::
|
||||
defines the frontend for the device. Occurs once per device element. You
|
||||
may override the default socket type.
|
||||
*backend*::
|
||||
defines the backend for the device. Occurs once per device element. You
|
||||
may override the default socket type.
|
||||
*set*::
|
||||
defines a socket option for the frontend or backend. The valid names are
|
||||
*hwm*, *swap*, *identity*, *subscribe*, *unsubscribe*, *rate*,
|
||||
*recovery_ivl*, *mcast_loop*, *sndbuf*, and *rcvbuf*. See
|
||||
linkzmq:zmq_setsockopt[3].
|
||||
*bind*::
|
||||
binds the frontend or backend to the specified endpoint. See
|
||||
linkzmq:zmq_bind[3].
|
||||
*connect*::
|
||||
binds the frontend or backend to the specified endpoint. See
|
||||
linkzmq:zmq_connect[3].
|
||||
|
||||
SOCKET TYPES
|
||||
------------
|
||||
|
||||
By default 'zmq_device' uses these socket types:
|
||||
|
||||
*queue* device::
|
||||
frontend is *xrep*, backend is *xreq*.
|
||||
*forwarder* device::
|
||||
frontend is *sub*, backend is *pub*.
|
||||
*streamer* device::
|
||||
frontend is *pull*, backend is *push*.
|
||||
|
||||
You can override the socket type for frontend or backend. The valid types are:
|
||||
*req*, *rep*, *xreq*, *xrep*, *sub*, *pub*, *pull*, *push*, and *pair*. See
|
||||
linkzmq:zmq_socket[3].
|
||||
|
||||
*Note*: if you use a *sub* socket you must explicitly set a subscription filter
|
||||
or your socket will not receive any data.
