  1. LoST discussion Oct. 11, 2011 Henning Schulzrinne

  2. urn:nena:service:sos.psap • What happens if accessed from outside (“local”) ESInet? • May violate “same result regardless of where you start” principle! • What if multiple ESInets are interconnected? • What happens if source & name-based routing are both used? • Always require both names?

  3. urn:nena:sos.responder • What happens if accessed from outside ESInet? • Distributed across all ESInets?

  4. Starting point • If a resolver has no cached mappings, should it be allowed to contact a tree node directly?  In other words, should we configure resolvers to start at a non-forest guide node.  Why or why not? • Should be able to start at any location. • Including “local” authoritative server that refers “up”. • May distribute load. • Maybe good second option in case FG is unreachable.

  5. Validation: findServiceResponse • Currently: indicates which elements are good/bad/indifferent • Extensions: • per-element options (Centreville, Centerville, Center Villa) • complete alternatives • How would non-human recipient judge which one is correct? • Large number of permutations • Any experience with auto-correction? • Based on typos? • Changes in municipality names? • Should there be a web interface for humans instead?
