摘要： A switch fabric access scheduler is disclosed. An indication is received that a link included in a plurality of links to the switch fabric is next in order to be serviced by a queue scheduling process common to the plurality of links. The queue scheduling process common to the plurality of links is used to determine, in a manner at least partly independent of each other link in the plurality, a queue to be serviced by the link.

摘要： Bounding cell reorder depth is disclosed. It is determined whether a reorder buffer that is associated with a switch fabric exceeds a depth limit. In the event that the reorder buffer exceeds the depth limit, backpressure with respect to a source associated with the reorder buffer is sent. In such cases source based back pressure information is included in a reserved field in a cell that is being sent into the switch fabric. In the event that the reorder buffer does not exceed the depth limit, the cell is sent to the switch fabric. In such cases the reserved field is present in the cell but is unused.
