Abstract: A segment routing-based data transmission method includes that a first network device receives a first packet from a second network device, where the first packet includes a first segment identifier (SID); the first network device obtains, based on the first SID, a first network slice identifier corresponding to the first network device; the first network device generates a second packet based on the first packet, where the second packet includes the first network slice identifier; and the first network device sends the second packet.
