Abstract: A path construction method and related devices are disclosed. The method may include: advertising, by a second PE node, a first VPN route to a first PE node through an MP-BGP signaling channel, such that the first PE node is able to determine a label forwarding path to a first VPN Prefix based on a first transmission path descriptor (TPD) carried in the first VPN route received; where the first TPD is configured to identify the label forwarding path for a first VPN message to reach a BGP next hop.

Abstract: A routing method, a routing device and a computer-readable storage medium are disclosed. The routing method includes: allocating, to each of network slices corresponding to different algorithm types, a segment identifier corresponding to a respective algorithm type, and flooding the segment identifier through an IGP; configuring, for each network slice, a QoS policy corresponding to a respective algorithm type; and, forwarding a packet based on the segment identifier and the QoS policy.

Abstract: Disclosed are a method and apparatus for sending a segment routing traffic engineering (SR-TE) policy, a method and apparatus for receiving an SR-TE policy, a network element, and a computer-readable storage medium. The method for sending an SR-TE policy includes creating an SR-TE policy instance by a first network element; and sending an SR-TE policy corresponding to the SR-TE policy instance to a second network element by the first network element, where the SR-TE policy carries path identifier information and primary/standby state information of a segment list so as to support fast reroute (FRR) of a segment list level.
