In the previous chapter, we looked at basic designs using OpenFlow, ACI, SnapRoute, and NSX. In this chapter, we will cover Quality of Service (QoS), which is an important part of any network. QoS is no longer an extra; it's a key part of networking, in both enterprise and service provider networks.
By the end of this chapter, you will:
- Understand what QoS is, both in layer 2 and layer 3 applications
- Understand how QoS is deployed and configured
- Know how to configure QoS using open source controllers
- Know how to configure QoS using NSX
