ABSTRACT Network Calculus is a powerful mathematical theory for the performance evaluation of communication systems; among others it allows to determine worst-case performance measures. This is why it is often used to appoint Quality of Service guarantees in packet-switched systems like the internet. The main mathematical operation within this deterministic queuing theory is the min- plus convolution of two functions. For example the convolution of the arrival and s...
