Abstract: An instruction writing method, apparatus, and network device are provided to reduce a requirement for a storage space of a microcode processor. The method includes obtaining, by a first device, first indication information, where the first indication information indicates the first device to enable a first service function, and writing, by the first device, a first microcode instruction set corresponding to the first service function into an unused storage space of a target microcode processor in a network processor, where a size of the unused storage space is greater than or equal to a size of the first microcode instruction set.

Abstract: This application provides a communication method and apparatus, so that in a movement process of the communication apparatus, when a neighboring relationship between different cells may continuously change, because the communication apparatus may perform communication by using different target bandwidth information based on different movement information, implementation complexity of PCI planning can be reduced, and communication performance can be improved. In the method, the communication apparatus determines target bandwidth information, where the target bandwidth information is associated with movement information of the communication apparatus; and the communication apparatus performs communication based on the target bandwidth 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.
