Abstract: This application discloses a method, and a device for load balancing in a BIER network. The method includes: a network device obtains a BIER packet, and determines, based on an identifier in the BIER packet, a target next-hop node that reaches a destination address of the first BIER packet from a plurality of next-hop nodes of the network device. Then, the network device generates a target forwarding table based on the target next-hop node, and forwards the first BIER packet based on the target forwarding table. In this application, a control plane does not perform load balancing on a BIER packet in a manner of delivering a large quantity of load balancing tables to a forwarding plane, but the forwarding plane of the network device generates the target forwarding table to perform load balancing on the BIER packet.

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.
