Abstract
A method of processing cells in a communication system includes obtaining a cell, causing it to be stored, determined if it is associated with a loss event, and if so, causing it to be tagged with a lost cell indicator. An apparatus for processing cells includes a cell processing module and a cell buffer interface that can interface with a cell buffer. The processing module is configured to obtain a cell, cause it to be stored through the buffer interface, determine if it is associated with a loss event, and if so, cause it to be tagged with a lost cell indicator. The lost cell indicator can preferably be a compressed lost cell indicator. The inventive tagging enhances computational efficiency compared to approaches that require moving a stored cell to make room for a complete dummy cell.
