Title:
METHOD FOR FORWARDING MESSAGE IN SR NETWORK, DEVICE, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/056945
Kind Code:
A1
Abstract:
A method for processing a message in an SR network, comprising: receiving a message, the message header of the message comprising a destination address field, a first pointer, a second pointer and a list for processing the message, the list comprising a plurality of identifiers arranged in sequence, the plurality of identifiers being mapped to a plurality of segments in the SR network on a one-to-one basis, and the value of the first pointer and the value of the second pointer together indicating the position of a first identifier among the plurality of identifiers in the list; determining the first identifier according to the value of the first pointer and the value of the second pointer; and copying the first identifier into the destination address field. In said method, a CL pointer is provided in a message header, and together with an SL pointer, forms a two-dimensional pointer, to indicate the position of a C-SID in an SID list. Thus, the message length is reduced, and the transmission efficiency and processing efficiency of a network are improved.
