Autonomic Communication Virtual Machine for Multimedia Applications

This project focuses on enhancing communication applications by self-configuring multiple frameworks within the Communication Virtual Machine (CVM). The goal is to expand medium coverage, incorporate additional communication frameworks, and enable NCB to adapt and utilize these layers seamlessly. The design involves creating bridges to integrate various frameworks like Google Talk and Skype into NCB without extensive rewriting. The Communication Service Manager serves as a centralized hub for managing multiple frameworks and autonomic computing principles are applied to optimize framework selection and usage. The project aims to publish research findings at esteemed conferences like SAC and address future work on refining Google Talk and JML functionality and addressing user availability issues.

  1. Self-configuring of multiple frameworks for NCB Sean Leslie Ricardo Tirado Graduate Students: Andrew Allen

  2. Problem/Motivation • Communication Virtual Machine • A new paradigm for developing new communication applications • Problem • Adding additional medium coverage to the CVM. • Motivation • Design NCB to be able to incorporate additional communication frameworks, and self-configure NCB to use these layers.

  3. Original Goals • Design a framework that self-configures NCB • Implement this design for NCB • Publish papers describing our research findings

  4. Outline • Recap • Literature Review • Design • Demonstration • Summary/Contribution • Future Work

  5. Recap • Identify the problem • Read, read, read • “User-Centric Network Communication Broker for Multimedia Collaborative Computing • “A Communication Virtual Machine” • Propose a solution • Incorporate multiple communication frameworks via a bridge. • Self-configure NCB to work with these frameworks

  6. Recap (cont.) • Research • Survey paper • Refine knowledge of the API (Google Talk, JML) • Design • Create an architecture that allows use of bridges within NCB but without rewriting all of NCB • Implementation • Write the code for NCB • Write the code for the bridges

  7. Design • Communication Framework • Google Talk, Skype, NCB, JML • Java API

  8. Design • Bridge • Interface implemented for each communication framework • Each bridge is particular to its communication framework

  9. Bridge Class Diagram

  10. Design • Communication Service Manager (CSM) • Contains the list of all the separate Bridge objects • Maintains the multiple communication frameworks • Concept of multiple frameworks is centralized here

  14. Design

  15. Design • NCB • Limited knowledge of the multiple frameworks • Maintains the communication session

  16. Design • UCM, SE, UCI • Unchanged

  17. Applying Autonomic computing to CSM • Knowledge • The communication bridge objects • Stored in a list

  18. Applying Autonomic computing to CSM • Monitor • Wait for an incoming request • Poll to get incoming communication information

  19. Applying Autonomic computing to CSM • Analyze • Analyze the request to determine what is being asked for • Generate a list of possible communication frameworks

  20. Applying Autonomic computing to CSM • Plan • Apply any kinds of preferences to the list of possible frameworks • Make a comparison

  21. Applying Autonomic computing to CSM • Execute • Hand off the bridge object to NCB

  22. Original Goals • Create a design that self-configures NCB • Completed • Implement this design for NCB • Mostly completed • Publish papers describing our research findings • 3rd Annual ACM Symposium on Applied Computing (SAC): Autonomic Computing Track • 46th ACM Southeast Conference Deadline for submission: Late November

  23. Future Work • Further implement Google Talk, and JML functionality • Handling various user availability issues • Constraints – User availability
