In some embodiments, a method includes sending a signal to a first module associated with a stage of a switch fabric and receiving a signal from the first module a first amount of time after sending the signal to the first module. A signal is sent to a second module associated with the stage of the switch fabric and a signal is received from the second module a second amount of time after sending the signal to the second module. The second amount of time is less than the first amount of time. A cell of a first data packet is sent to the first module and a cell of a second data packet is sent to the second module a third amount of time after sending the cell of the first data packet. The third amount of time is associated with the difference between the first amount of time and the second amount of time.

A network device includes a main storage memory and a queue handling component. The main storage memory includes multiple memory banks which store a plurality of packets for multiple output queues. The queue handling component controls write operations to the multiple memory banks and controls read operations from the multiple memory banks, where the read operations for at least one of the multiple output queues alternates sequentially between the each of the multiple memory banks, and where the read operations and the write operations occur during a same clock period on different ones of the multiple memory banks.

A device may include a compressor. The compressor may receive a first number of inputs, each of the inputs having a predetermined width. The compressor may also compute a one's complement sum of the first number of inputs to generate carry bits having the predetermined width and sum bits having the predetermined width, modify the carry bits by moving a most significant bit of the carry bits to a least significant bit position, and output the modified carry bits and the sum bits.

A multi-chassis network device may automatically detect whether cables connected between chassis devices are correctly inserted. The device may insert, into a first data stream output from a first port of the device, control information identifying the first port. The device may receive, from a second data stream received by the first port of the device, second control information identifying a second port, at another device connected to the device via a cable. The device may determine, based on the second control information, whether the connection of the first port to the second port, via the cable, is valid and cause, when the connection of the first port to the second port is determined to not be valid, the device to output an indication that the connection is not valid or to reconfigure the device to make the connection of the first port to the second port valid.

Some embodiments of the invention provide a forwarding element that can be configured through in-band data-plane messages from a remote controller that is a physically separate machine from the forwarding element. The forwarding element of some embodiments has data plane circuits that include several configurable message-processing stages, several storage queues, and a data-plane configurator. A set of one or more message-processing stages of the data plane are configured (1) to process configuration messages received by the data plane from the remote controller and (2) to store the configuration messages in a set of one or more storage queues. The data-plane configurator receives the configuration messages stored in the set of storage queues and configures one or more of the configurable message-processing stages based on configuration data in the configuration messages.

Examples described herein relate to a network interface device that includes circuitry that is to: receive a packet; replicate the packet based on a multicast configuration; and determine a number of replicate packets that differ from the received packet. In some examples, circuitry is to receive hash value that comprises a hash of a portion of the packet and circuitry is to determine a hash value of the replicated packet.
