I don't know if I can do a complete dump in this email.
Hope the following helps to clarify a little better ...
...
Also, what is the difference between zeroconf, discovery, and multicast?
Discovery refers to either a client (producer or consumer) establishing a
'transport connector' to the broker
or a broker establishing 'network connector' to another broker without
explicit static configuration of broker (IP or hostname).
The scheme 'multicast' refers to either listening for or advertising
discovery events on a multicast address.
zeroconf is similar to multicast, expect for protocol specific to Apple's
Rendezvous (bonjour).
Broker
=====
<networkConnectors>
<networkConnector name="default" uri="multicast://default"/>
</networkConnectors>
The above configuration in the broker xml file will make it automatically
establish network connectors to other brokers that advertise themselves on
the multicast address: when this broker gets a discovery event from another
broker, the event has information that enables it to establish network
connector to that broker.
Self-advertisement is facilitated by the following config:
<transportConnectors>
<transportConnector name="default" uri="tcp://localhost:61616"
discoveryUri="multicast://default"/>
</transportConnectors>
Client
====
An example usage of discovery on the client side (using the transport
'discovery' that uses discovery agent) ...
<transportConnectors>
<transportConnector name="default"
uri="discovery:(multicast://default)"/>
</transportConnectors>
ps: discovery (which is a confusing name) is just like a 'reliable'
transport. If it is unable
to connect to a broker, it will try another broker (assuming it
heard its advertisement over multicast).

Could anyone provide me with an example of discovery configuration from
their
xml configuration file? My head's spinning after reading through the
forums
and the documents. I'm not really clear on what needs to be configured in
the xml file and what the clients need to use to connect.
Also, what is the difference between zeroconf, discovery, and multicast?
e.g., which is more performant...?
Thanks very much!
