csma-cd-timing's Introduction

CSMA-CD-timing

The program simulates network with N hosts sending frames. The output of program is timecode when each station begun succesful transmition of frame.

Build

Using meson

meson setup builddir
cd builddir
meson compile # ... or if meson < 0.5.5, use ninja

Using pure gcc

gcc *.c

Run

If you have used meson run with ./csmacd otherwise use ./a.out.

Arguments

--help - shows help message
-n - number of stations(default: 5)
--frame-size - size of frame(default: 1518)
--max-attempt - how many station can retry before stopping(default: 10)

Example of results

$ ./csmacd -n 10 --max-attempt 16

Also in such table instead of timecode can be string FAILED which means that station exceeded it's attempts to send frame
