Subject MQ architecture query
Date Tue, 16 Nov 2010 03:56:25 GMT

Hi guys,

I'm investigating ActiveMQ for a trial in the following scenario:
1. End-customer own ships/planes/boats (3-5 vessels) that are linked to the
HQ on land via Satellite
2. Satellite provisions on-demand datalink
3. Data will need to be sync between HQ and vessels on a regular basis
4. Satellite data charges are relatively expensive, so we need to try to
reduce it

I am thinking of
1. 1 ActiveMQ per vessel, 1 ActiveMQ at HQ (HA/failover can be implemented
2. Data to be sync-ed to the other side will be placed on the local ActiveMQ
3. HQ will access data on ship by connecting to ActiveMQ instance on vessel
4. Vessel will access data at HQ by connecting to ActiveMQ instance there
5. Configuring ActiveMQs to use UDP instead of TCP to save on comms overhead

Would this approach work?
1. Will using UDP help to reduce the comms overhead? Each network packet
sent (whether full or not) is charged
2. Should I skip the main MQ instance in the HQ?

Any advice / suggestions and criticisms are welcomed and needed.

Thank you very much... :)))
