DiffServ-Aware Traffic Engineering (DS-TE)
So far, you've seen that DiffServ service with MPLS packets is basically the same thing as with IP packets, with a few differences in configuration. Overall, MPLS packets with a given EXP setting are treated just like IP packets with a given IP Precedence setting.
There's more to MPLS TE and DiffServ than just applying IP mechanisms to MPLS packets, though. The rest of this book spends a great deal of time showing you that there's benefit in making a headend resource-aware, because the headend can then intelligently pick paths through the network for its traffic to take. However, after you add QoS, you're almost back at square one. Things are better than they were—you can steer IP traffic away from the ...
