Multi-level buffer system dynamically allocates storage for data units arriving at network gateway, and retrieves stored data units according to hierarchical schedule. Minimum and maximum thresholds associated with system resource and storage availability determine acceptance and storage of data units. Data units are accepted preferably if all threshold criteria are met. Threshold criteria may be determined from reserved minimum buffer length, calculated maximum buffer length, or random early discard-type algorithm applied separately to each buffer level. Optionally, buffer management applies to non-hierarchical storage systems.
