  3. E-mail standards evolution survey • Evolutionary Mission • SMTP and MIME extensions • POP3 and IMAP4 clients • Client Submission profiles for VPIM/IVM • Web browsers -- 3rd party email clients • Client Retrieval profiles for VPIM/IVM • Web browsers -- Thin clients • Multi-modal -- Mobile Issue: Have we neglected to cite other relevant contributions? jkwong@nortelnetworks.com

  4. GUI Internet Messaging Client Models: GUI (E)SMTP (client-server) (E)SMTP (server-server) GUI RFC-822/MIME desktopclient MTA UA MTA MR email server MTA – Message Transfer Agent UA – User Agent MR – Message Store envelope and content HTTP,POP3 or IMAP4 jkwong@nortelnetworks.com

  7. 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 Are there other UM design principles? jkwong@nortelnetworks.com

  8. 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 Detailed Requirements Summary • Message Submission Limitations • Forward without download • Quota by context enforcement • Future Delivery Support • Notification • Message Store to Notification protocol jkwong@nortelnetworks.com

  9. 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 Issue: Additional requirements, especially for WUI? jkwong@nortelnetworks.com
