I would like to draw a diagram for packets scheduling in networks similar to the this one:

enter image description here

The same type of diagram (or very similar) can be used also for tasks scheduling.

Can you please indicate a template for this? Or a resource I could use.

Thanks a lot. The copyright for the image belongs to the authors from here.

Do you know about the pgfgantt package? See ctan.org/pkg/pgfgantt . This package typesets Gantt charts. – Yori May 27 '12 at 17:21
knulp created a task diagram package. Check this: tex.stackexchange.com/questions/29679/pdflatex-and-pstricks – user22273 Nov 18 '12 at 17:32
