Abstract: This application discloses a method and an apparatus for obtaining a shared maximum segment size MSS, and a storage medium, and belongs to the field of communications technologies. In this application, a first device may obtain a first parameter after a Transmission Control Protocol TCP connection is established, obtain a first MSS based on the first parameter, and further obtain a first shared MSS based on the first MSS and a second MSS. After the TCP connection is established, when a parameter of the TCP connection changes, the first device updates a shared MSS based on a changed parameter, and may use an updated shared MSS to transmit a packet. This helps save network resources and improve transmission reliability.
