摘要： Embodiments of the present invention disclose a packet processing method, including: obtaining, by a first network node, a format of a segment identifier of a second network node, where the format is used to describe a location and a length of each field in the segment identifier of the second network node, and the segment identifier of the second network node includes a first field; determining, by the first network node, a value of the first field in the segment identifier of the second network node based on a segment routing policy and the format of the segment identifier of the second network node, and adding the determined value of the first field to a second packet sent to the second network node, where the determined value of the first field is used to indicate the second network node to process the second packet. In the embodiments of the present invention, a prior-art problem that a programming capability of a network node is affected because an obtained format of a segment identifier of the network node cannot be displayed can be resolved.

摘要： Embodiments of this application provide a bit-forwarding ingress router, a bit-forwarding router, and an OAM test method, and pertain to the field of multicast networks. A first BFR receives an OAM request packet from a BFIR; the first BFR determines, according to the OAM request packet, that a destination BFR corresponding to the OAM request packet is the first BFR; and the first BFR obtains a first OAM response packet according to an ID of the BFIR, and sends the first OAM response packet to the BFIR. According to the method and the apparatus that are provided in the embodiments of this application, a problem that a BFIR cannot diagnose or handle a transmission fault when the fault occurs during transmission of a multicast packet can be resolved, which helps implement connectivity testing by using an OAM packet and enables testing of multiple BFERs.

摘要： Embodiments of the present invention disclose a method for forwarding a packet, and a network device. The method includes: receiving, by a first network device, a first packet, where the first packet includes first indication information, payload data, and a packet sequence number of the first packet in a data flow corresponding to the first packet; when the first network device determines that the first packet includes the first indication information, generating, by the first network device, a plurality of second packets based on the first packet, where each of the plurality of second packets includes the payload data, the packet sequence number, and second indication information; and separately forwarding, by the first network device, the plurality of second packets to a second network device over different forwarding paths in a plurality of forwarding paths, where the second indication information is used to instruct the second network device to discard a packet in the plurality of second packets except a packet that first reaches the second network device. According to the embodiments of the present invention, reliability of packet forwarding can be improved.
