Chapter 20

Traffic Engineering for Circuit-Switched Networks

We can never judge the lives of others, because each person knows only their own pain and renunciation. It's one thing to feel that you are on the right path, but it's another to think that yours is the only path.

Paulo Coelho


In this chapter, we present traffic engineering for circuit-swtiched networks. In particlar, we define the offered load in Erlangs and its relation to blocking for a given capacity. We also discuss blocking computation in the presence of dynamic routing without or with trunk reservation.
