M&S-based design of embedded controllers on network processors
Rodrigo Castro, Iván Ramello, Matías Bonaventura, Gabriel Wainer · 2012
We introduce advanced techniques to develop embedded real-time controllers for networking applications using a Modeling and Simulation (M&S) based methodology. Our solution relies on the DEVS formalism and the Embedded CD++ (ECD++) real-time simulator. We show how DEVS-based prototypes can be embedded in the target hardware, consisting of an Intel IXP2400 Network Processor. We developed interface libraries allowing DEVS models to interact with specialized microcontrollers for high performance packet handling. We also introduce a portable Virtual Lab for developing prototypes and deploying them for quick validation on a real-world network. Our approach provides model continuity, eliminating the need for adapting logic or structure of the controllers when evolving from standalone simulations to execution in the target platform.
