摘要： This application discloses a method for generating a segment list used for packet forwarding in an SRv6 network. The method includes: A network device obtains an original segment list corresponding to a packet forwarding path, where the original segment list includes original segment identifiers that are sequentially arranged, and each of the original segment identifiers that are sequentially arranged corresponds to one node or link on the packet forwarding path; the network device compares a plurality of successively adjacent original segment identifiers in the original segment list, to generate a plurality of successively adjacent compressed segment identifiers, where a length of each compressed segment identifier is less than a length of a corresponding original segment identifier; and the network device generates a compressed segment list, where the compressed segment list includes a plurality of compressed segment identifiers, and the compressed segment list is used to forward a packet along the packet forwarding path. In the method, the compressed segment identifier is generated based on the original segment identifier, where the length of the compressed segment identifier is less than that of the original segment identifier, and a length of the compressed segment list is less than that of the original segment list. This improves packet transmission efficiency and processing efficiency in an SR network.

摘要： Embodiments of the present invention provide a data sending method, including: respectively receiving, by a forwarding device by using a first FlexE group and in multiple timeslots included in a first timeslot set, multiple first encoded data blocks generated by a physical coding sublayer; determining, by the forwarding device according to the multiple timeslots included in the first timeslot set and the first FlexE group, a second FlexE group and multiple timeslots included in a second timeslot set; and respectively sending, by the forwarding device, the multiple first encoded data blocks by using the second FlexE group and in the multiple timeslots included in the second timeslot set. According to the data sending method in the embodiments of the present invention, the forwarding device does not need to process the first encoded data blocks in a conventional layer 2 (link layer) or layer 3 (network layer) forwarding mode. Therefore, a processing delay can be reduced, and a transmission delay can be reduced.
