Today, we'll cover Queueing Theory. So that completes network layer stuff
(graphs, routing, errors, queueing)
Note in the printed (and old online pdf) queuing theory slides, there was a font error on some slides with \rho being rendered as ~n.
I've fixed it on the PDFs online (its ok in the ppt). apologies (again).
Next week we start on Flow Control, and hopefully get up to control theory.
