In March 2000, the ITU-T established Recommendation E.106, A Description of
an International Emergency Preference Scheme (IEPS). This Recommendation
presents the basic requirements for preferential treatment of critical
communications to support recovery operations from serious disasters such as
earthquakes and severe storms. While E.106 is based upon Public Switched
Telephone Network (PSTN) services, considerable effort is underway to
migrate these capabilities to next generation networks based upon Internet
technology.
note - this effort is focused at recovering the society from a serious
disaster, not recovering the network, I think.
The first issue of pursuit is to ensure an effective interface between the
PSTN and IP-telephony services.
this strikes me as a profoundly strange approach, but I may be biased.
It is expected that this interface will
touch on a number of work areas in the IETF. Many of the capabilities and
protocol mechanisms may already exist and need to be identified and adapted
as necessary. There could also be some areas where additional work may be
needed. Nevertheless, we expect that coordination and interaction with
various IETF work areas will be needed to help fulfill the requirements for
IEPS in next generation networks.
Reactions I've heard vary from "their ideas are just too broken for words"
to "what they want can be built easily using DiffServ - this should be a
call for tender, not a standardization proposal".
Clarity of desired outcome may be a Good Thing.
At IETF 48 in Pittsburgh we had a BOF on IEPS where the background and
considerations for IEPS were presented. We hope to have another BOF with
more detailed discussion at IETF 50 in Minneapolis. Two Internet Drafts on
IEPS have been posted and are available at www.iepscheme.net along with
other relevant documents. We also have established an Email List for
discussion of the IEPS issues. You are invited to subscribe using the
instructions provided at the IEPS web site and contribute to the discussions
and progress of work.
Mentioning the location of the mailing list may not be a bad idea.
Many thanks for you interest and support.
