In this chapter, we learned about developing the performance architecture for a network. The performance architecture consists of determining which performance mechanisms (QoS, prioritization, scheduling, traffic conditioning, SLAs, and policies) apply to a particular network, where each mechanism may apply, and the relationships within the performance architecture and between performance and other component architectures.
The performance architecture is the first of the component architectures that we will be examining. As we go through each component architecture, the reference architecture (consisting of all the external relationships) for the network will emerge.
