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

7Design  Communication Framework –Google Talk, Skype, NCB, JML –Java API

8Design  Bridge –Interface implemented for each communication framework –Each bridge is particular to its communication framework

9 Bridge Class Diagram

10Design  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

11 Design

12 Design

13 Design

14 Design

15Design  NCB –Limited knowledge of the multiple frameworks –Maintains the communication session

16Design  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
