Abstract: A segment routing device receives a first packet from a first network. A first packet header of the first packet includes a segment list. The segment list includes a plurality of sequentially arranged identifiers. The identifiers include a first-type identifier and a plurality of second-type identifiers. Network devices or links identified by the first-type identifier and the second-type identifier are respectively on the first network and a second network. A type of the first network is different from a type of the second network. The segment routing device encapsulates a second packet header for the first packet to form a second packet. The second packet header includes the plurality of second-type identifiers. The segment routing device sends the second packet to the second network.

Abstract: This application provides a circuit, a chip, and an electronic device. The circuit includes a first processor and a first processing module connected to the first processor. The first processing module includes a second processor connected to a first memory. A transmission latency generated when the second processor performs read and write operations on the first memory is less than a transmission latency generated when the first processor communicates with the first processing module. Because the transmission latency generated when the second processor performs the read and write operations on the first memory is less than the transmission latency generated when the first processor communicates with the first processing module, a cost of a transmission latency of data in a bus can be reduced.

Abstract: A data processing apparatus includes a searching module, a first functional module (FM), and a second FM. The first FM implements a service sub-function of a first category. The second FM implements a service sub-function of a second category. The searching module determines first entry data based on first data in target data, and determines second entry data based on second data in the target data. The first data is related to a first service sub-function. The second data is related to a second service sub-function. The first service sub-function belongs to the first category. The second service sub-function belongs to the second category. The first FM performs a first functional operation based on the first data and the first entry data. The second FM performs a second functional operation based on the second data and the second entry data.

Abstract: A data processing method applied to a programmable chip, includes a logic classification unit (LCU) that obtains, based on first data received through a data bus, at least first target classified data (TCD) and second TCD, and sends the first and second TCD to a corresponding first arithmetic logic unit (ALU) and a corresponding second ALU based on a preset mapping relationship. The LCU classifies target execution information obtained through preprocessing an entry by a ternary content addressable memory (TCAM) and service data, so that an instruction memory determines first and second information, and sends the first and second information to the corresponding first and second ALUs. The first and second ALUs respectively send, through the data bus, data obtained through performing calculation based on the first TCD and the first information and data obtained through performing calculation based on the second TCD and the second information.

Abstract: This application provides a packet processing method, including: receiving, by a current network node, a first packet; determining, by the current network node, a flow identification corresponding to the first packet, where the first packet does not include the flow identification; obtaining, by the current network node based on the first packet and the flow identification, a second packet, where the second packet includes the flow identification and an IOAM header, and in the second packet, the flow identification is located before the IOAM header; and sending, by the current network node, the second packet to a next network node. This resolves a problem that as a quantity of passed IOAM nodes increases, traffic classification performed by a subsequent node consumes a longer delay, thereby deteriorating forwarding performance.
