Abstract
Approaches, techniques, and mechanisms are disclosed for reutilizing discarded link data in a buffer space for buffering data units in a network device. Rather than wasting resources on garbage collection of such link data when a data unit is dropped, the link data is used as a free list that indicates buffer entries in which new data may be stored. In an embodiment, operations of the buffer may further be enhanced by re-using the discarded link data as link data for a new data unit. The link data for a formerly buffered data unit may be assigned exclusively to a new data unit, which uses the discarded link data to determine where to store its constituent data. As a consequence, the discarded link data actually serves as valid link data for the new data unit, and new link data need not be generated for the new data unit.
