The present invention provides a method and apparatus for packet transmission in the network. When the network device receives data packets from the first user, the network device extracts and saves the data encapsulated in the data packets and then forwards the packets according to the destination addresses of the data packets. When it receives the request from a second user for the data mentioned above, it encapsulates the saved data in data packets and sends the data packets to the second user. With the present invention deployed, the uploaded data packets are saved on network devices and can be directly transmitted to users requesting them. In this way, the present invention avoids repeated traffic upload, reduces upload traffic in the network, decreases network bandwidth occupied by traffic, and thus improves the overall network performance.
