Presentation Transcript

  1. TINA Information models and computational models Lill Kristiansen All figures are from TINA Service Architecture: http://www.item.ntnu.no/~lillk/docs/sa50-main.pdf

  2. Comment / guide • Often information models gives an idea of what the system is about, but these information models are rather detailed, and it might be as usefull to look at the information model and the computational model somewhat in paralell.

  3. TINA Session information models

  4. Session class hierarchy

  5. Relation between access and service

  6. Session graph • Allows sessions with multiple parties

  7. Multiparty, multimedia • Allows parties with multiple stream bindings (including 0 streams) • Allowing control relationsships • Adding, moving and controlling: • who participates • which streams are established • At an information view, no comp.modelling her

  8. More session graph features

  9. SI: stream I/F SFEP: SF endpoint Info model: streams

  10. Computational View: • accesss related • UA User Agent (in prov.dom) • PA Provider Agent (in user dom.) • Note: PA correspons somewhat to SIP-notion: to user-agent-client and user-agent-server • Service (usage) related: • SSM Service Session manager (in prov. dom.) • USM User Service Session Manager (in prov.dom) • UAP User Application (in user domain) • CSM Communication Sess. mgr. (in prov.dom) • TCSM Term.CSM (in user/terminal domain)

  11. Invite someone to existing session

  12. More examples • See more computation examples in TINA doc. ch. 7.4 • Will be provided as handouts from institute office
