**Usage:**
This procedure is registered under

}
**Errors:**
The procedure may raise the following errors:
* ``crossbar.error.invalid_configuration`` - the provided transport configuration is invalid
* ``crossbar.error.already_running`` - a transport with the given ID is already running (or starting)
* ``crossbar.error.cannot_listen`` - could not listen on the configured listening endpoint of the transport
* ``crossbar.error.class_import_failed`` - a side-by-side component could not be instantiated
**Events:**
The procedure will publish an event when the transport **is starting** to
* ``crossbar.node.<node_id>.worker.<worker_id>.on_router_transport_starting``
and publish an event when the transport **has started** to
* ``crossbar.node.<node_id>.worker.<worker_id>.on_router_transport_started``

"""
Start a transport on this router and return when the transport has started.
**Usage:**
This procedure is registered under
* ``crossbar.node.<node_id>.worker.<worker_id>.start_router_transport``
The procedure takes a WAMP transport configuration with a listening endpoint, e.g.
.. code-block:: javascript
{
"type": "websocket",
"endpoint": {
"type": "tcp",
"port": 8080
}
}
**Errors:**
The procedure may raise the following errors:
* ``crossbar.error.invalid_configuration`` - the provided transport configuration is invalid
* ``crossbar.error.already_running`` - a transport with the given ID is already running (or starting)
* ``crossbar.error.cannot_listen`` - could not listen on the configured listening endpoint of the transport
* ``crossbar.error.class_import_failed`` - a side-by-side component could not be instantiated
**Events:**
The procedure will publish an event when the transport **is starting** to
* ``crossbar.node.<node_id>.worker.<worker_id>.on_router_transport_starting``
and publish an event when the transport **has started** to
* ``crossbar.node.<node_id>.worker.<worker_id>.on_router_transport_started``
