The outer scheduler separates delay sensitive applications from the incoming burst of multi-part data and also decides whether to apply Aggregated -MAC Service Data Unit (A-MSDU) aggregation technique or to send the data without any aggregation. The inner scheduler schedules the remaining (delay-insensitive, background and best-effort) packets using Aggregated-MAC Protocol Data unit (A-MPDU) aggregation technique.
