Subject ActiveMQ Topology Question - possible?
Date Wed, 23 Jun 2010 12:05:27 GMT

Hi there,

I'm considering a distributed system of loosely coupled nodes organized in a
tree structure of depth 2 or 3 (including the root). I'm considering using
ActiveMQ/JMS as means of communicating between the tree nodes.

Within the tree the communication pattern between the nodes is as follows:

1) shared data published from the root node should be disseminated
(downwards) to all the child nodes?

2) the root node should be able to send data (downwards) to each individual
child node - again one level at a time.

3) each child node should be able to send data (upwards) to the root node -
one level at a time.

Can I model such a communication scheme with ActiveMQ/JMS?

The figure here illustrates what I would like to achieve; 1) the black
arrows representing the downwards publishing from the root to all the nodes,
2) the red arrows, indicating the downwards sending from the root to a
single node, and 3) the blue arrows, indicating the upwards sending from a
single child node to the root node.
