  1. Message Sessions draft-ietf-simple-message-sessions-01 Ben Campbell

  2. Changes

  3. SDP Format List • Accept-wrapped-types attribute • Format list items can occur anywhere • Wrapped list items can only occur wrapped in types mentioned in format list.

  4. Session Inactivity Timers • Session state expires if no SEND activity. • Checks in both directions • Standard Timer set to 1 minute • Had planned to determine value through “engineering exercise” – any thoughts?

  5. Standard port • Not really a default—port is always explicit. • Only for convenience of network administration.

  6. New Architectural Considerations Section • Use of relays • Large contents on separate sessions • Why no connection sharing

  7. Security Changes • Changed digest algorithm to SHA1 • Added TR-ID and S-URI to digest • S/MIME instead of CMS • Rules for MSRPS usage.

  8. Miscellany • New Abstract • Clarified use of sdp port field • Sequence diagram added to example flow • Several minor clarifications • IANA registration for URL scheme

  9. Open Issues

  10. Clean Shutdown • Should endpoint make sure no pending SENDs before ending a session? • Is knowledge that message was not delivered good enough?

  11. 426 Response Code Extensibility • Do we need a way to specify protection types other than TLS?

  12. Standard inactivity timer value • Currently 1 minute
