Abstract: A method includes determining a first data sending rate based on multiple round-trip times (RTTs), where the multiple RTTs include RTTs of a plurality of first probe packets sent at different sending rates, and the first sending rate is a sending rate corresponding to an RTT that is in the multiple RTTs and that is less than a first preset threshold; determining a second sending rate based on a plurality of packet loss rates, where the packet loss rates include packet loss rates of a plurality of second probe packets sent at different sending rates, and the second sending rate is a sending rate corresponding to a packet loss rate that is less than a second preset threshold; and sending a third probe packet at a third sending rate.

Abstract: A packet forwarding method includes that a session management network element sends a path identifier to a first device, where the first device includes an access network element corresponding to a protocol data unit (PDU) session and a user plane network element corresponding to the PDU session, the PDU session corresponds to a first terminal, the path identifier indicates a first path from the access network element to the user plane network element, the first path includes a part or all of a second path, and the second path is a path corresponding to a PDU session pre-established by the session management network element for a second terminal. The session management network element further sends, to the first device, identification information of a destination address corresponding to the path identifier.
