Nov Draft History compiled from: - draft-burger-um-reqts-00.txt - draft-vaudreuil-um-issues-00.txt - draft-wong-umcli-00.txt 4 sections: – standards evolution survey –Client Models for profiles –General UM Design Principles –Detailed Requirements

Nov Issue: Have we neglected to cite other relevant contributions? standards evolution survey Evolutionary Mission –SMTP and MIME extensions –POP3 and IMAP4 clients –Client Submission profiles for VPIM/IVM Web browsers -- 3rd party clients –Client Retrieval profiles for VPIM/IVM Web browsers -- Thin clients Multi-modal -- Mobile

Nov Internet Messaging Client Models: GUI UA RFC-822/MIME (E)SMTP (client-server) MR MTA (E)SMTP (server-server) GUI HTTP, POP3 or IMAP4 envelope and content GUI desktop client server MTA – Message Transfer Agent UA – User Agent MR – Message Store

Nov Internet Messaging Client Models: TUI RFC-822/MIME (E)SMTP (client-server) MR MTA (E)SMTP (server-server) TUI voice messaging system UM server proprietary API IETF Protocol UA MTA – Message Transfer Agent UA – User Agent MR – Message Store

Nov Internet Messaging Client Models: WUI UA RFC-822/MIME (E)SMTP (client-server) MR MTA (E)SMTP (server-server) WUI TUI voice messaging system UA UM server Handset display client HTTP, POP3 or IMAP4 GUI WUI MTA – Message Transfer Agent UA – User Agent MR – Message Store

Nov Are there other UM design principles? General UM Design Principles –Reuse Existing Protocols –Maintain Protocol Integrity –Sensible Message Context –Preserve Internet Infrastructure –Meet Near-Real-Time Telephony Requirements –Be Scalable, esp. for Video –Provide user functionality as close as possible to that experienced using a separate traditional mode

Nov Detailed Requirements Summary Performance Requirements in Retrieval –Real-time Playback –Avoid Base-64 Data inflation Functional Limitations in Retrieval –Context in mailbox summary –Context in mailbox sort –Context in mailbox quota –Functional mailbox conventions& support Inbox, sent items, deleted items, expired item –CLID Restriction indication / preservation –Committed delivery to full mailbox Message Submission Limitations –Forward without download –Quota by context enforcement –Future Delivery Support Notification –Message Store to Notification protocol
