  1. Synchronizing Location-to-Service Translation (LoST) Serversdraft-schulzrinne-lost-sync-00 Henning Schulzrinne IETF68 - ECRIT

  2. Motivation • Synchronization of forest guides, resolver clusters and authoritative servers • Particularly if operated by different jurisdictions or across different vendors • may not be able to use standard database sync IETF68 - ECRIT

  3. Peering • FG - FG • AS - FG, AS - AS • AS push coverage regions “up” the tree, towards the FG • manually configured peering relationships • long-term static IETF68 - ECRIT

  4. Distribution (push) • <pushMappingsRequest> • pushed to peers • replace existing mappings with same id IETF68 - ECRIT

  5. Pull synchronization • <getMappingsRequest> • provide current list of mappings • obtain missing or updated mappings <?xml version="1.0" encoding="UTF-8"?> <getMappingsRequest xmlns="urn:...:sync"> <m source="lost:authoritative.example” sourceId="abc123" version="1"/> </getMappingsRequest> IETF68 - ECRIT

  6. Open Issues • Error conditions • Update <mapping> according to LoST IETF68 - ECRIT
