This chapter covered several thingsa brief look at the DiffServ architecture and its interaction with IP and MPLS packets, the MQC, and DS-TE.
Many tools are available to help you build QoS policies on your network. Here are the two main points to take away from this chapter:
Applying the DiffServ architecture to MPLS packets is not much different from applying it to IP packets.
DS-TE helps you solve the same problem for QoS that "regular" MPLS TE solves for link bandwidth, and in the same manner.
You can put as much or as little work as you like into your QoS policy. Whatever you can do with IP, you can do with MPLS. The resource awareness and source-based forwarding that MPLS TE gives you let you do even more with QoS in your network.
