However, to change the subport level bandwidth, existing hierarchy needs to be dismantled and whole process of building hierarchy under subport nodes needs to be repeated which might result in router downtime. Furthermore, due to lack of dynamic configuration of the subport bandwidth profile configuration (shaper and Traffic class rates), the user application is unable to dynamically re-distribute the excess-bandwidth of one subport among other subports in the scheduler hierarchy. Therefore, it is also not possible to adjust the subport bandwidth profile in sync with dynamic changes in pipe profiles of subscribers who want to consume higher bandwidth opportunistically. This patch series implements dynamic configuration of the subport bandwidth profile to overcome the runtime situation when group of subscribers are not using the allotted bandwidth and dynamic bandwidth re-distribution is needed the without making any structural changes in the hierarchy. The implementation work includes refactoring the existing data structures defined for port and subport level, new APIs for adding subport level bandwidth profiles that can be used in runtime.
