Abstract: Methods and apparatus for two-layer Alpha-based buffer management with dynamic RED. A two-layer hierarchical sharing scheme using alpha parameters is provided. A buffer is dynamically shared across upper-level entities, such as hosts, using one set of alpha parameters, then a dynamically-adjusted buffer portion allocated for an upper level entity is shared among its lower level entities (e.g., sub queues) using a separate set of low-level alpha parameters. The memory spaces for the upper- and lower-level entities may be dynamically redistributed. Determinations to drop and/or mark and ECN field of received packets are performed using Dynamic RED, which employs dynamic thresholds and associated dynamic probabilities.
