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:

1) Literature Review and Feature Analysis

2) 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.

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

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
