Consider that we have two applications using MPLS with traffic engineering. One application is delay sensitive (DS), such as a real-time voice or video application. The other application is throughput sensitive (TS), such as a file transfer application or a high-volume remote sensor feed. Now consider the following settings defined by the user for the ingress node of a requested LSP:

Where the S values are user specified and may differ for each entry.

a. Which row is more appropriate for DS and which for TS?

b. Consider the following two policies: (1) drop packet if PDR is exceeded. (2) drop packet if PDR or PBS is exceeded; mark packet as potentially to be dropped, if needed, if CDR or CBS is exceeded. Which policy is more appropriate for DS and which for TS?
