Abstract: This application provides for data transmission between first and second network devices. The first network device requests information from the second network device and in return receives grant information from the second network device. The grant information includes at least a first sequence number that is used by the first network device to determine a first credit limit, where the first credit limit is an amount of data allowed to be sent by the first network device in a packet-distributed load sharing manner. The first network device sends data to the second network device based on the first credit limit. Second and third sequence numbers are also described.

Abstract: A packet edit processing method and a device are provided. In an embodiment, the method includes: generating an input packet template based on N to-be-edited protocol header fields of an input packet, and a preset protocol field mapping relationship, where the input packet template includes N protocol descriptors, and the protocol field mapping relationship is a mapping relationship between a protocol field included in a protocol descriptor and a protocol field included in a protocol header field; performing edit processing on the input packet template to obtain an output packet template; and converting, based on the preset protocol field mapping relationship, M protocol descriptors into M protocol header fields of an output packet, and replacing the N protocol header fields in the input packet with the M protocol header fields to obtain the output packet.
