Abstract
A packet transmission method and apparatus, and a computer storage medium, and relates to the field of communications technologies. A first device obtains service type information of an original packet. The first device generates an encapsulating security payload (ESP) packet of the original packet based on a target security association, where the ESP packet includes a packet header, an ESP header, a service type field, a first encrypted part, and an ESP authentication data field, and the service type field includes the service type information. The first device sends the ESP packet to a second device. The second device parses the service type field to obtain the service type information of the original packet. The second device performs a target operation on the ESP packet based on a service policy and the service type information of the original packet.
