MQSeries.net :: View topic - Multi-hop or IB

Hi all,

Background
We have a requirement in our project, where QM1 needs to talk to QM2 but does not have communication between them at all.
However, QM1 has intermittent communications with QM3 (say 10 AM 30 minutes) and QM3 has intermittent communications with QM2 (say 10 PM for 30 minutes).

What we are effectively required to do is routing in this case (I understand this is routing, please correct if I am wrong).

One option that is available to us is to use queue manager clusters (dunno whether feasible or not)
Option two is to use multi hop and send messages from QM1 to QM2 via QM3.
Option 3 is to have an IB on QM1 which will send messages to QM3 and the IB at QM3 will then decide that these set of messages are not for me but for QM2 so redirect them to QM2.

Questions
1) Which option from the above should be preferred, and why?
2) Are there any other options which we can consider?

Note
The systems where these 3 queue managers are existing are mobile systems and may move geographically, such that few days down the line, QM1 has intermittent communication with QM4 and QM4 has intermittent communication with QM2. Further down the line QM1 might have direct communications with QM2, in which case it needs to have a point to point.
We are looking at a solution that will involve minimum administrative work in terms of creation of new queues etc.

I hope that I was able to state my problem clearly.
Any help, suggestions, solutions would be highly appreciated.

Thanks & Regards,
Sumeet
