There is also some work in the IETF on the more general problem of distributing early warning messages: <http://tools.ietf.org/wg/atoca> Right now, they're taking a pretty layer-7 approach (distributing CAP in SIP messages), but part of their charter is figuring out how this application relates to things like iPAWS, CMAS, 3GPP PWS, etc. So they will likely end up looking at some layer-2/3 aspects of the problem as well. --Richard On Thu, Dec 2, 2010 at 4:42 PM, Jay Ashworth <jra () baylink com> wrote:

At the moment, they're working on the "replace the EAS backbone" part of it, which work is about a year behind schedule, and everyone wants an extension, but there are other useful places to apply some effort. I'm a designer, not a coder, so I've been piddling around in the part I'm good at; thinking about design. Some of the results are here: http://www.incident.com/cookbook/index.php/Rough_consensus_and_running_code and http://www.incident.com/cookbook/index.php/Alerting_And_Readiness_Framework and I invite off-list email from anyone who has suggestions to toss in the pot.
