Abstract: A packet processing method and apparatus, related to the communication field are provided. The method includes: re-encapsulating a first packet from a first device to obtain a second packet, where the first packet includes first identification information and first service function chain (SFC) header encapsulation information, the second packet includes first index information and the first identification information and does not include the first SFC header encapsulation information, and the first index information is associated with the first SFC header encapsulation information and the first identification information; and sending the second packet to the second device based on the first SFC header encapsulation information. This can avoid impact on packet transmission after the second device modifies the identification information.
