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.

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.
A service curve mapper comprising:
- a first module adapted to define a plurality of traffic classes each traffic class being characterized by a bandwidth and a delay priority;
- and
- a second module adapted to compute 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.
