Subject Re: Network of brokers dynamic discovery and directional question
Date Mon, 09 Aug 2010 11:22:55 GMT
A network connector is a "demand forwarding bridge" so it is one way
by default, unless it is configured duplex=true, in which case, the
initial forwarding connection is used to create another bridge in the
opposite direction, reusing the connection. With multicast discovery,
the same config can result in a one way bridge to every discovered

The description "demand forwarding bridge" explained; demand, based on
the consumer advisories coming from the target, and forwarding,
meaning locally created consumers created by the bridge forward their
messages to the target.
