Specifying Software Architectures Based On
Coloured Petri NetsWenxin Wu, Motoshi Saeki

• Architecture and Design Patterns
• Assignment 2

2
Major Software Architecture Issues

• Simulate and Analyze Software architecture
• This is possible thanks to
• Colored Petri Nets (CPN)
• Design Patterns
• Tools to study CPN

3
Identification Of Shaws or POSA patterns

• Pattern is the basic brick of this work.
• A CPN is provided for Pipe and Filter
• The Blackboard pattern is the example of
  application
• Composite patterns
• Pattern itself

4
Integration issues?

• None to the best of my knowledge.
• Using this work will help to give quantitative
  results of the performance of a system, may help
  to detect sensitive parts, bottlenecks. This may
  help to
• Detect where integration problem may occur
• Compare different architectures

5
Theoretical or Empirical ?

• Neither theoretical nor empirical, mostly
  descriptive.
• A bit more theoretical, they give the feeling
  about why their idea works, but further reading
  is needed.

6
Unresolved issues

• Deviation from patterns
• Domain specific component
• How to extract parts?
• How to make them more reusable?
• Retrieve parts
• Dynamism of software architectures
• How to study large CPN

7
Conclusion

• Good and simple idea. All the component are
  present, they had to get the idea of mixing them.
• Give enough facts to arouse interest, one may
  feel like playing with a pattern and simulate it
  to understand better how useful it might be.
