[sr-dev] Proposed Change to DMQ Notification Address Resolution

[Robert Boisvert]

DMQ Developers,

Our team would like to setup a DMQ bus
<http://kamailio.org/docs/modules/4.2.x/modules/dmq.html#idp2640048> that
contains more than one notification address
<http://kamailio.org/docs/modules/4.2.x/modules/dmq.html#dmq.p.notification_address>
to support a high availability, fault-tolerant system where multiple
servers are used to maintain the list of DMQ nodes.  The failure of any one
DMQ node or the startup order should not cause the DMQ bus to lose track of
available nodes.  As nodes go offline and online the DMQ bus should be
updated using information from the active nodes.   To do this we propose
changing the way DMQ uses the notification address.

Currently the notification address resolves a DNS name to a single IP
address even if a SRV record or multiple A/AAAA records are available.  The
proposal is to use all the A/AAAA records or SRV targets returned from a
DNS name query as notification addresses.

Do you have any comments, concerns, suggestions, or recommendations
regarding this proposal?  Your input is definitely welcome.

Thank you,
Bob
