FEDERATION COMPOSITION PROCESS AND TOOL SUPPORT

• Ole Martin Mevassvik,
• Norwegian Defence Research Establishment (FFI)

2
PRESENTATION OVERVIEW

• Concept
• Introduction to Federation Composition Process
• Federation Architecture
• Tool Support
• Demo
• Summary

3
FEDERATION COMPOSITION

• Assembling Simulation Components into a
  Federation Design using the SE System
  Specification as input

4
CONCEPT

• Reduce time and cost in developing a Federation
  by reusing existing Simulation Assets
• Searching for existing Simulation Assets stored
  in a distributed repository
• Component based architecture
• Integrated tool support

5
COMPONENT BASED FEDERATES

• A federates may internally be composed by a
  federation
• A bridge is introduced between the federations
• Advantages
• Federate configurability
• Security
• Complexity
• Different types of RTIs
• Performance

FEDERATION COMPOSITION PROCESS

• Inputs from Step 1 and 2
• Scenario
• Conceptual Model
• System Requirements
• Evaluation Data Requirements
• Outputs
• Architecture
• Asset responsibility
• Federation Object Model
• Federation Agreements
• Bridge design impl

7
FEDERATION AGREEMENTS

• Agreements that must be reached among federates,
  which are not necessarily documented in the FOM
• Agreements necessary for providing a fully
  consistent interoperable distributed simulated
  environment
• Databases to establish fair fight
• Key algorithms (line-of-sight, kill algorithms,
  )
• Operational issues addressed and resolved among
  federates, e.g. initialization procedures,
  save/restore policies.

8
FEDERATION COMPOSITION TOOL (FCT)

• Integrated Tool Support
• Supports both bottom-up and top-down design

9
KEY FUNCTIONALITY

• Support all necessary book-keeping and guide the
  user through the different steps and tasks for
  iterative federation composition and design
• Support for editing a federation architecture and
  assigning requirements to federates.
• Support for searching Candidate Simulation Assets
  in the Repository.
• Support for assessing Candidate Simulation Assets
  against allocated requirements.

10
KEY FUNCTIONALITY, cont.

• Support for consistency checking of a Federation
  Design.
• Support for FOM creation and editing.
• Support for documenting Federation Agreements.
• Support for the development of Federation
  Bridges.

FCT - BENEFITS

• Reuse Component based solutions improves the
  potential for reusing the simulation assets as
  opposed to complete simulations.
• Customisation Traditional federates are
  monolithic in scope. A composable federate can be
  tailored to user requirements through assembly of
  specific simulation models.
• Security Provide technical solutions for the
  encapsulation of algorithms for certain parts of
  the federate, or federation (encryption in
  Bridge).
