n is now vital. It is therefore also time to redraw the classical FP diagram in Figure 3.2. When complemented with 'the new layer' and adapted to the structure of Figure 3.26 it gets a look according to Figure 3.27. When looking at Figure 3.27 the following view should be applied: The figure shows a service factory with a service production line. The service production (= service plan) extends to all layers. All other FPs have a direct or indirect contribution to and impact on the service product. Many FPs have QoS features, such as transmission, switching and routing, which impact on the service. See also the Chapter 7. QoS adaptation protocols are provided at the top of the service production line.
