From: The IESG To: IETF-Announce Subject: Protocol Action: 'A Dynamic Host Configuration Protocol (DHCP) based Location-to-Service Translation Protocol (LoST) Discovery Procedure' to Proposed Standard Message-Id: <20080603130228.D593A28C10D@core3.amsl.com> Date: Tue, 3 Jun 2008 06:02:27 -0700 (PDT) Cc: ecrit chair , Internet Architecture Board , ecrit mailing list , RFC Editor The IESG has approved the following document: - 'A Dynamic Host Configuration Protocol (DHCP) based Location-to-Service Translation Protocol (LoST) Discovery Procedure' as a Proposed Standard This document is the product of the Emergency Context Resolution with Internet Technologies Working Group. The IESG contact persons are Jon Peterson and Cullen Jennings. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-ecrit-dhc-lost-discovery-03.txt Technical Summary The Location-to-Service Translation Protocol (LoST) describes an XML- based protocol for mapping service identifiers and geospatial or civic location information to service contact Uniform Resource Locators (URLs). LoST servers can be located anywhere but a placement closer to the end host, e.g., in the access network, is desirable. Such a LoST server placement provides benefits in disaster situations with intermittent network connectivity regarding the resiliency of emergency service communication. This document describes how a LoST client can discover a LoST server using the Dynamic Host Configuration Protocol (DHCP). Working Group Summary There is consensus in the WG to publish this document. Protocol Quality Although the LoST specification has been implemented there are no implementations known for the DHCP-based discovery procedure. From a deployment point of view it is likely that the DNS-based discovery procedure will be available before this document will see a deployment.
