> URL: https://issues.apache.org/jira/browse/QPID-7263
> Project: Qpid
> Issue Type: Improvement
> Components: Java Broker
> Reporter: Keith Wall
>
> One possible deployment pattern for HA is that clients reference the HA group
> via a VIP rather than utilising a failover url. This isolates the client
> from knowledge of the individual node addresses. This deployment pattern is
> currently possible but it needs a relatively deep integration: custom
> scripting is required to track the location of the master node (using the
> Java Broker's REST API) with changes causing the VIP's target to be updated.
> VIPs usually have a feature which is able to detect when a target is down
> (port closed) and direct traffic to another target instead. In our case,
> this feature cannot be used become the Broker continues to listen on the Port
> even if the Virtualhost is not the master. (This is because in the model a
> services many virtual hosts).
> It would be desirable if a cleanly integration could be found:
> * somehow arranging for Ports associated with HA to become unbound when the
> mastership goes away.
> * perhaps by providing an additional 'ping' port related to the virtualhost
> that is only bound when the master is present at the node.
