Abstract:
1. A method of controlling a rate shaper that manages network data traffic output by a network device, the method comprising: receiving a first traffic class specification for a first traffic class, wherein the first traffic class specification includes a first traffic class priority; receiving a second traffic class specification for a second traffic class, wherein the second traffic class specification includes a second traffic class priority lower than then first traffic class priority; defining first and second two-piece service curves for the first and second traffic classes, respectively, wherein the second two-piece service curve is associated with a delay time value based on at least the first and second traffic class priorities, wherein the delay time value represents a shift in time of the second two-piece curve to form a corresponding three-piece service curve; and using the corresponding three-piece curve and/or two-piece curves as part of rate shaping done by the rate shaper.
