Purpose of this Draft

• Provide a catalog of high-level BCPs derived from
  experience in operating large enterprise and
  consumer IM communities
• Two categories of recommendations in this draft
• A recommended minimum profile for SIMPLE
  implementations to satisfy expectations of real
  world users
• E.g., implementation of activity from RPID
  draft
• Techniques that can assist in scalability and
  accuracy of presence/IM info in large and very
  large deployments

What is an Interdomain Issue?

• SIP/SIMPLE is essentially a point to point (user
  to user) protocol
• But, these users often exist within an
  administrative domain
• Enterprises
• Consumer services
• ISPs or mobile access providers
• By recognizing these domains, we can achieve
  efficiencies and optimizations
• However, many of these BCPs can apply to the
  point to point case as well.

4
What Kinds of Efficiencies?

• Multiplexing of multiple dialogs over the
  connection between edge proxies
• Optimizations that allow a proxy to cache certain
  kinds of responses on behalf of identifiers in
  its namespace
• Recommendations on timeouts, refreshes,
  compression and security usage and use of Page
  Mode and Session Mode (MSRP) for IMs

5
History of the Draft/Change Log

• Draft originated asdraft-levin-simple-interdomain
  -reqs-03.txt
• Separated provisioning and scalability
  requirements into requirements drafts
  (draft-houri-speermint-rtc-provisioning-reqs-00
  and draft-rang-simple-problem-statement-00)
• Removed discussion of non-MSRP session-based
  protocols
• Simplified language and made more consistent with
  a BCP
• Note current draft was submitted with an
  incorrect expiry date this will be fixed after
  the moratorium

6
Next Steps

• Does the WG see utility in documenting this kind
  of information?
• Is this the right information to cover?
• Are there others with operational experience to
  contribute?
