SERVICE FLOW PROCESSING METHOD AND DEVICE

Embodiments of this application disclose a traffic flow processing method and apparatus for traffic flow transmission and protection. The method includes: generating and configuring first configuration information for a first edge node, where the first configuration information is used to: replicate a data packet included in a received traffic flow, output, to a first relay node, a first data packet obtained through replication, and output, to a second relay node, a second data packet obtained through replication; generating and configuring second configuration information for the first relay node, where the second configuration information is used to: replicate the first data packet, output, to the second relay node, a third data packet obtained through replication, and obtain and output a first received data packet in a fourth data packet obtained through replication and a fifth data packet from the second relay node; and generating and configuring third configuration information for a second edge node, where the third configuration information is used to: obtain a first received data packet in a data packet from the first relay node and a data packet from the second relay node.
