A network device, such as a network switch, can include an ingress to receive data packets from a network. The ingress can communicate with an egress included in the network device though a fabric included in the network device. At least one of ingress and the egress can enqueue a data packet prior to receipt of all cells of the data packet. The ingress can also commence with dequeue of the cells of the received data packet prior to receipt of the entire data packet from the network. At least one of ingress and the egress can process the data packets using cut-through processing and store-and-forward processing. In a case of cut-through processing of a data packet at both the ingress and the egress of a network device, such as CIOQ switch, the fabric can be allocated to provide a prioritized virtual channel through the fabric for the data packet.

Early queueing network device

A system includes a task scheduler to select a queue from a port. The port includes a determined number of cell slots between pick opportunities. The task scheduler selects a queue at a pick opportunity. A queue manager connects with the task scheduler to pop cell packets from the selected queue, and to send update information to the task scheduler. The update information includes information of how the queue manager expects to fill the cell slots between the task scheduler selections. The task scheduler makes subsequent queue selections based on the update information.

Multiple cell dequeue for high speed queueing

Techniques, systems and apparatus are described for implementing an inter-channel ring interface in a communication device. A communication device can include communication channels to carry data at respective first data throughputs. An inter-channel ring interface connects at least some of the communication channels in a ring configuration to form an aggregated group of channels that operates as a single channel at a second data throughput.
