Federation Execution - Problem

• Problem
• A user per computer
• Needed communication between persons when
  federation execution is failed
• Performance must be adjusted

Current RTI Federation Execution - Static
4
Federation Execution - Solution

• Solution
• A user controls all computer
• Resource sharing
• Performance must be always best
• Cost low

Dynamic

The Proposed Framework 1/2
6
The Proposed Framework 2/2

• RTI-dependent Services
• Resource monitoring
• Federation communication
• RTI-independent Services
• Decision of priority
• FTP

7
Sequence Diagram 1/2
8
Sequence Diagram 2/2

• RMF requires the resource information from
  Resource Federate
• Resource Federates response
• RMF decides the priority of resource information
• RMF transfers the federates to the hosts
• RMF commands the start of federation
• Federation executes
• When Federation ends, inform the end to RMF

9
Configuration of Federates 1/2

• Resource federate is executed as daemon at all
  computer
• Resource Federation
• Application federation is executed to the hosts
  transferred by RMF
• Application Federation
• Sometimes communication between Application
  Federation is needed

10
Configuration of Federates 2/2
11
Communication between Federation 1/2
12
Communication between Federation 2/2

• Communication between Federation is needed
• Multi Port Federate (MPF) method is used
• RMF (Resource Manager Federate) is MPF
• RMF is responsible for synchronization
• RMF provides data communication between
  federations

13
Addition of Resource Dimension 1/2
14
Addition of Resource Dimension 2/2

• Resource addition of communication dimension
• Dynamic network management
• Better performance
• Resource addition of application (federate)
  dimension
• Deployment
• Platform-independent
• Dynamic execution environment

15
Future Work and Conclusions
Application

• Security
• The proposed framework can provide the dynamic
  characteristic to existing RTI federation
  execution environment
