Re: [earlywarning] What problem is ATOCA trying to address?

It is not that simple. For example if you attempt to run Twitter over a wireless network and try to handle a large number of alerts (consider the EAN case) then congestion will result in delays. This is why SMS does not work and as more data enabled devices are used multicast/broadcast is essential.

We're not at the mechanism state yet.  While I imagine that the mechanisms
may include something that is "if you have multicast, use it", I don't think
that would be enough because multicast is not enabled in way too many
networks.  Sites like Twitter show us that we can get enough messages sent
out in reasonable periods of time without multicast.
