SERVICE CURVE MAPPING
First Claim
1. A method for configuring service curves for managing the output port of a networking device, the method comprising:
- defining a plurality of traffic classes each traffic class being characterized by a bandwidth and a delay priority; and
computing a plurality of traffic service curves each associated with a different one of the plurality of traffic classes, at least one of the plurality of traffic service curves being characterized by a shifted two-piece linear function shifted such that the service curve limits service to during a nonzero time period prior to the start of the two-piece linear function.

Abstract
A method for configuring service curves for managing the output port of a networking device includes the following steps. A multitude of traffic classes is defined, each traffic class being characterized by a bandwidth and a delay priority. A multitude of traffic service curves is computed, each of the plurality of traffic service curves is associated with a different one of the multitude of traffic classes. At least one of the multitude of traffic classes service curves is characterized by a shifted two-piece linear function shifted such that the service curve limits service to during a nonzero time period prior to the start of the two-piece linear function.

24. A method for configuring service curves for managing the output port of a networking device, the method comprising:
-
configuring, according to user input, one or more traffic classes, wherein each class is assigned a bandwidth and a priority; and
computing a service curve for each of the one or more traffic classes, each as a function of the bandwidth and priority assigned to that class.
