Question
I want to know whether xmpp publish-subscribe functionality send notifications to all subscribers simultaneously(broadcasts) or sends notifications in a queue i.e. one by one.
I want to know the difference between pub-sub and jaxl class which i am using because the jaxl sends push messages in queue that is one user at a time.
Solution
Depends on the implementation. Bare XEP-0060 PubSub implementation would send separate event
notification message
s to all subscribers.
However, there are other extensions such as XEP-0033 Extended Stanza Addressing that allows multicast addressing of message
s.
