Title:
SERVICE TRANSMISSION METHOD, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/231442
Kind Code:
A1
Abstract:
Embodiments of the present invention provide a service transmission method, a device, and a storage medium. The method comprises: a first network device receives Border Gateway Protocol-labeled unicast (BGP-LU) routing information from a second network device, the BGP-LU routing information comprising a plurality of pieces of Color attribute information, and each piece of Color attribute information comprising a Color value and a Slice label corresponding to the Color value; and when a service packet from a third network device is received, determining a target tunnel from a Slice entry according to a Slice label carried in the service packet, and forwarding the service packet to the second network device by means of the target tunnel. A plurality of LSPs respectively corresponding to different Color values are established between cross-domain end-to-end network devices, and each LSP corresponds to an underlying network slice resource.
