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?

PDR PBS CDR CBS EBS Frequency 1 S S =PDR =PBS 0 Frequent 2 S S S S 0 Unspecified
