Simulation models

This page makes available simulation models developed as part of the Gigabit Ethernet Project. Unless otherwise stated, all software is made available here for open use with no restrictions. The models all require the CSIM18 function libraries. CSIM18 is a commercial product available from Mesquite Software, Inc.

Switch models

Several models of output queued (OQ), input queued (IQ), combined input and crossbar queued (CICQ), and virtual input queued parallel packet switches (VIQ PPS) have been developed. Models have been developed for both cell and variable-length packets versions. Each model is contained in a zip file with a readme.txt describing build and execution of the model.

Simple OQ switch (cell and packet).
IQ with iSLIP, PIM, and PP-VOQ scheduling (cell and packet).
IQ with iSLIP scheduling and PAUSE flow control and two-levels of priority packet).
CICQ with RR/RR and OPF/RR scheduling (cell and packet).
CICQ with RR/RR scheduling using block transfers (packet).
VIQ PPS (cell) and existing designs for comparison:
- Iyer PPS with centralized scheduling (cell)
- Iyer PPS with distributed scheduling (cell)
- Khotimsky et al. PPS (cell)
- Saad et al. PPS (cell)

Additional models are available. Contact to Ken Christensen (christen@csee.usf.edu) to make sure you have the latest model version. CSIM18 must be obtained directly from the vendor (Mesquite Software, Inc.).
