Abstract

The invention comprises a method and apparatus for discarding frames in a communications device. In accordance with the method of the invention, a plurality of cells are received representing a plurality of frames wherein each cell comprises a data portion and a header portion including a cell loss priority indicator. At least some of the cells are stored in a buffer. It is determined if the number of cells in the buffer exceeds a first threshold when a first cell including an end of file marker is received. A series of cells received between the first cell and a second cell are discarded if the first threshold was exceeded in the determining step and if the cell loss priority indicator for a cell in the series of cells is set to a first state. The second cell comprises a cell including an end of file marker.
