Abstract

The Location-to-Service Translation (LoST) Protocol 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. In disaster situations with intermittent network connectivity, such a LoST server placement provides benefits regarding the resiliency of emergency service communication.

Abstract

   The Location-to-Service Translation (LoST) Protocol 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.  In disaster situations with intermittent network    connectivity, such a LoST server placement provides benefits    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).
