Abstract
In an enhanced partial packet discard (PPD) methodology, if an end-of-packet cell is discarded for non-PPD reasons, all non-end-of-packet cells of the immediately following packet are discarded. When an end-of-packet cell may validly be discarded, a switch faced with an end-of-packet cell may discard that cell if the last cell admitted to the buffer was an end-of-packet cell. To reduce the likelihood of having to drop end-of-packet cells, a buffer is configured to include a partial packet discard threshold such that the buffer space between that threshold and the end of the buffer is reserved for use by end-of-packet cells.
