  1. Communication Virtual MachineFeature Analysis & Policy Definitions Paola Boettner Mansi Gupta PhD Students Andrew Allen & Yali Wu

  2. Motivation • Provide users with a Communication Paradigm takes into consideration: • Rich functionality • User priorities • User preferences • CVM is the solution

  3. What is CVM? CVM is a new paradigm for developing collaborative communication applications.[1]

  4. Project Description Explore communication frameworks and analyze user needs to form policy structures for CVM Tasks: • Literature Review and Feature Analysis • Policy Definitions

  5. Literature Review • Identifying various communication frameworks • Exploring each framework: • Core Features • Additional Features • API • Scan developer websites, follow links, experiment with features • Compile findings and analyze them using domain analysis

  6. Domain Analysis[12] • Domain analysis is the process of analyzing related software systems in a domain to find their common and variable parts. • It is a key method for realizing systematic software reuse. • Several methods for domain analysis have been proposed, producing models such as feature tables and feature diagrams.

  7. 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) in order to allow successful software re-use.

  8. Importance of Feature Analysis • Provides a generic description of the requirements of systems. • Provides a basis for understanding the problem space addressed by software in the domain. • Proposes a set of approaches for the implementation of new systems.

  9. Yahoo! Messenger[5] • Chat & Email • PC-to-PC, PC-to-Phone, Phone-to-PC (Conferencing Available) • File transfer • Video Chat (Conferencing Available) • Text Messaging • Voicemail • JavaScript/C++ API <http://messenger.yahoo.com/features/>

  10. AOL Instant Messenger (AIM)[7] • Chat & Email • PC-to-PC, PC-to-Phone, Phone-to-PC • Video Chat • File Transfer • Text Messaging • Java, C/C++ API <http://help.channels.aol.com/kjump.adp?articleId=222487>

  11. Android[4] • Chat • PC-to-PC • Video Chat • File Transfer • Java API <http://code.google.com/android/documentation.html>

  12. Other Frameworks • Skype[10] • JML • GoogleTalk[11] • Windows Live Messenger[6] • Blackberry OS[8] • Palm OS[9] • NCB Native

  13. Feature Table Comments: *Audio conferencing in Skype depends on Hardware Single Core Processors- a maximum of 4 people allowed Dual Core Processors- more than 4 people allowed

  14. Feature Diagrams: Syntax Paradigm title Colored-in Circle: Required Feature Open Circle: Optional Feature Filled Arc: And/Or Features Empty Arc: Either/Or Features

  15. Feature Diagram

  16. Next Steps • 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. • Identify policy structures: • Use comparative study of features • Identify user needs by creating common scenarios • Create a GUI for users to create their policies
