A network device includes one or more dies, wherein each die, of the one or more dies includes one or more packet forwarding components and a switch fabric component. The switch fabric component of a particular die, of the one or more dies, may be connected to the one or more forwarding components of the particular die, and may be configured to provide a switching plane for the one or more packet forwarding components of the particular die. A first die, of the one or more dies, may be connected to the one or more packet forwarding components of a second die of the one or more dies, and may be configured to provide a switching plane for the one or more packet forwarding components of the second die. The switch fabric component may be included in each of the one or more dies and the network device does not include a standalone switch fabric component.

In some examples, a switching system includes a plurality of fabric endpoints and a multi-stage switching fabric. A fabric endpoint of the system is configured to receive, via the switch fabric, a plurality of cell streams, wherein each cell of a cell stream of the plurality of cell stream is associated with a sequence number that defines a correct ordering of cells of the cell stream; assign subsequences of each cell stream of the plurality of cell streams to respective reorder engines of the fabric endpoint; concurrently reorder the assigned respective subsequences to produce respective ordered subsequences for the subsequences, wherein the ordered subsequences are ordered according to the correct ordering of the corresponding cell stream; interleave the respective ordered subsequences for each cell stream to produce reordered cell streams each having correctly ordered cells; and process each reordered cell stream according to the corresponding correct ordering of cells.

In one embodiment, a processor-readable medium can store code representing instructions that when executed by a processor cause the processor to receive a value representing a congestion level of a receive queue and a value representing a state of a transmit queue. At least a portion of the transmit queue can be defined by a plurality of packets addressed to the receive queue. A rate value for the transmit queue can be defined based on the value representing the congestion level of the receive queue and the value representing the state of the transmit queue. The processor-readable medium can store code representing instructions that when executed by the processor cause the processor to define a suspension time value for the transmit queue based on the value representing the congestion level of the receive queue and the value representing the state of the transmit queue.
