Abstract
Process Petri nets are an ideal modeling language for depicting
the architecture of computer-based systems such as a broadband switch
platform because: 1) computers are process systems, and 2) complexity of
computer systems requires a hierarchical abstraction capability to
understand the system well. Petri nets also allow one to exploit the
dualistic nature of transformation and place to model complex process
systems in a versatile, yet formal, manner as well as analyze the
system's use of resources and operational performance characteristics.
This paper introduces dualistic Petri nets (dP-nets) and how they are
used to depict the architecture of an SS7 protocol stack engine on an
already-existent broadband switch platform during the engine's
development process. dP-nets were used to establish the scope of the
problem space and differentiate subsystems during the requirements
analysis phase guiding further development of high-level designs in the
solution space. Analysis of critical path and bottleneck process
performance can also give support to architectural decisions
