Abstract
A method for providing a service for a traffic flow includes a network device receives a first packet; and when a packet feature of the first packet matches a packet feature of the traffic flow, the network device encapsulates an indication identifier of the traffic flow into the first packet to obtain a second packet, and sends the second packet. The second packet is an Internet Protocol (IP) version 6 (IPv6) packet or a Multiprotocol Label Switching MPLS packet. The indication identifier indicates the service provided for the traffic flow.
