Document Type and Number:
WIPO Patent Application WO/2021/036328
Kind Code:
A1
Abstract:
Disclosed is a message forwarding method. The method comprises: receiving a message, wherein the first message header of the message comprises a segment list used for forwarding the message, the segment list comprises a plurality of identifiers that are sequentially arranged, each of the plurality of identifiers separately corresponds to a network device or a link, the list comprises a first element having the length of 128 bits, the first element comprises at least two adjacent identifiers of the plurality of identifiers, and the first message comprises a first pointer; according to the value of the first pointer, determining the position of the first identifier in the first element, wherein the first identifier is one of the at least two identifiers; copying at least one identifier starting with the first identifier into the second message header of the first message so as to generate a second message; and transmitting the second message. By means of the method, the present invention can reduce the length of the segment list and improve the efficiency of message transmission.
