Packet Switch

26 Mar 2002 (Updated 20 Jul 2009)

Simulink® and Stateflow® model of a simple packet switch.

File Information
Description	Simulink® and Stateflow® model of a four input, four output packet switch. The model includes variable length packet generators, FIFO managers, a scheduler, and a crossbar. Instructions: Unzip to a new folder, change the MATLAB current directory to this folder, then open the 'packet_switch' mdl file. Open the Stateflow charts inside the FIFO managers to view the switch's operation during the simulation. This model is described in the animated demonstration called 'Packet Switch' on this page: http://www.mathworks.com/products/dsp_comm/demos.shtml
Required Products	Simulink Stateflow
MATLAB release	MATLAB 6.1 (R12.1)
Other requirements	Made with Simulink 4.1.1 (patch) and Stateflow 4.2.0 (patch) available for download from the web site.

26 Nov 2002	James Moffatt	This is a very useful introduction to using Simlink/Stateflow to model packet networks. I could understand the Stateflow diagram for packet generation on the first pass!
31 Jul 2003	Abdullah Gani	it is very useful stuff, indeed.
30 Oct 2004	Mauro Pinto	I need a tutorial pass by pass about Stateflow of Matlab
