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

7. 7 CVM Structure [1] User Communication Interface (UCI) Synthesis Engine (SE) User-Centric Communication Middleware (UCM) Network Communication Broker (NCB) 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. Motivation Background Project Description ObjectivesWork Deliverables

8. 8 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. Motivation Background Project Description ObjectivesWork Deliverables

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

10. 10 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 Motivation Background Project Description Objectives Work Deliverables

11. 11 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) Motivation Background Project Description Objectives Work Deliverables

12. 12 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 Motivation Background Project Description Objectives Work Deliverables

16. 16 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 Motivation Background Project Description Objectives Work Deliverables
