This is a network of brokers: http://activemq.apache.org/networks-of-brokers.html In a network of brokers, messages are not load balanced across the brokers. However, by default, ActiveMQ uses a round robin dispatch policy so that active consumers on a destination get an equal distribution of messages. Messages are distributed across the brokers based on demand from active consumers on q1 on each broker. But note that if there are no consumers on q1 on a given broker, messages will not be distributed there. Additionally, each consumer's prefetch limit will play a part in message distribution as well: http://activemq.apache.org/what-is-the-prefetch-limit-for.html Bruce -- perl -e 'print unpack("u30","D0G)u8...@4vyy9&5R\"F)R=6-E+G-N>61E<D\!G;6%I;\"YC;VT*" );' ActiveMQ in Action: http://bit.ly/2je6cQ Blog: http://bruceblog.org/ Twitter: http://twitter.com/brucesnyder
