Abstract
A traffic manager includes an execution unit that is responsive to instructions related to queuing of data in memory. The instructions may be provided by a network processor that is programmed to generate such instructions, depending on the data. Examples of such instructions include (1) writing of data units (of fixed size or variable size) without linking to a queue, (2) re-sequencing of the data units relative to one another without moving the data units in memory, and (3) linking the previously-written data units to a queue. The network processor and traffic manager may be implemented in a single chip.
