Abstract: The present disclosure provides a packet encapsulation method, including: determining a segment routing-traffic engineering (SR-TE) path; generating, according to a segment identifier (SID) of each node in the SR-TE path, an SID list, where each node supports a plurality of unified-SID encapsulation types (UETs) corresponding to SIDs of different lengths, and in the SID list, the SID of at least a node serving as an intermediate node of the SR-TE path is the SID having the non-longest length in the plurality of SIDs corresponding to the node; forming a segment routing header (SRH) from the SID list; and encapsulating an initial packet with the SRH to obtain a final packet. The present disclosure further provides a packet forwarding method, a UET announcement method, an electronic device, and a computer-readable storage medium. The final packet obtained by the packet encapsulation method has a higher load rate.

Abstract: Methods and devices for constructing a label and forwarding a label packet are provided. A node receives a message which carries a segment list and a segment list Identifier (ID) for identifying the segment list. The node constructs a label forwarding table according to the segment list and the segment list ID, and performs forwarding according to the label forwarding table; and/or the node maintains a mapping relationship between the segment list and the segment list ID.
