2. Motivation Background Project Description Objectives Work Deliverables Motivation • Michael & Elias want to share their photos: • Free chat or calls • Easy file transfer • Need a conference to add Seychelles & Jairo

3. Motivation Background Project Description Objectives Work Deliverables Motivation • Sergeant Robert Parks (in Iraq) wants to speak with his superior officers (in the US): • Good quality of voice • Cost is not an issue

4. Motivation Background Project Description Objectives Work Deliverables Motivation • Courtney wants to talk to Steve: • Free way of talking to each other • Video

5. Motivation Background Project Description Objectives Work Deliverables Motivation • Communication Paradigm takes into consideration: • Rich functionality • User priorities • User preferences • CVM is the solution

6. Motivation Background Project Description Objectives Work Deliverables What is CVM? • CVM is a new paradigm for developing collaborative communication applications.[1]

7. Motivation Background Project Description Objectives Work Deliverables CVM Structure[1] • UCI – provides users with an interface to interact with CVM. • SE – contains algorithms to automatically synthesize a user communication schema instance to an executable form (communication control script) • UCM – executes communication control script and manages the delivery of communication services. • NCB – provides an API to the UCM and delivers communication services.

8. Motivation Background Project Description Objectives Work Deliverables CVM Design[1] • Currently CVM operates with: • JML, Skype[10], Google Talk[11], NCB Native • Autonomic Computing: • Self Configuration: Paradigm shift on the development of today’s communication applications.

9. Motivation Background Project Description Objectives Work Deliverables Project Description • Explore communication frameworks and analyze user needs to form policy structures for CVM

10. Motivation Background Project Description Objectives Work Deliverables Objectives • Literature Review on existing frameworks • Conduct a feature analysis of communication frameworks: • Survey core and additional features of various frameworks. • Compilation & comparative study of features according to commonalities and variabilities • Identify policy structures: • Use comparative study of features • Identify user needs by creating common scenarios • Create a GUI for users to create their policies

11. Motivation Background Project Description Objectives Work Deliverables Feature Analysis[2] • The process of identifying, collecting, organizing and representing information in a domain based on the study of existing systems and development histories. • Take into account the ways in which the systems are alike (core features) and how they differ (additional features)

12. Motivation Background Project Description Objectives Work Deliverables Feature Analysis (Contd)[2] • Features may be defined as: • Mandatory: (Core Features) • baseline features of an application • Example: Audio or Chat • Alternative or Optional: (Additional Features) • Specialization of more general features • Example: Emoticons

13. Motivation Background Project Description Objectives Work Deliverables Core Features[3] • Chat (one to one & Conference) • Audio (one to one & Conference) • Video (one to one & Conference) • File transfer • Contact List

14. Motivation Background Project Description Objectives Work Deliverables Additional Features[3] • Emoticons • Online status • Avatar Images • Voicemail • Scrolling marque text

15. Motivation Background Project Description Objectives Work Deliverables Communication Frameworks • Android[4] • Yahoo! Messenger[5] • Windows Live Messenger[6] • AIM (AOL Instant Messenger)[7] • Blackberry OS[8] • Palm OS[9]

16. Motivation Background Project Description Objectives Work Deliverables Policies • A policy is a set of considerations designed to guide decisions on courses of action. • They are rules that define the choices in the behavior of a system. • They include 4 common elements:[3] • Scope: what is or is not the subject of the policy • Condition: when a policy is to be applied • Business Value: labels relative priority allowing to make economic trade-offs. • Decision: describes desired outcome of a policy

17. Motivation Background Project Description Objectives Work Deliverables Deliverables • Technical Report • Papers: • SAC: • 24th Annual ACM Symposium on Applied Computing • Deadline for submission: August 16th, 2008 • ACM Southeast • 47th Annual ACM Southeast Conference.
