    Abstract: The embodiments of the invention provide a method for establishing a wireless local area network tunnel, an apparatus, and an access network system. An AC sends a first configuration message to an AP, where the first configuration message includes a first tunnel establishment configuration parameter, and the first tunnel establishment configuration parameter includes information about binding between an IP address of at least one BRAS and at least one SSID, so that the AP establishes a data tunnel with the BRAS according to the first tunnel establishment configuration parameter, and the AC establishes a control tunnel with the AP, thereby separating the data tunnel from the control tunnel, and reducing unnecessary overheads of the AC.

    Abstract: A data flow migration method and device are disclosed. When migration between a source virtual machine and a target virtual machine is started, determining a silent time used for processing data flow migration; and receiving, within the silent time, a data flow packet sent by a switching node; and sending the data flow packet to the target virtual machine according to the data flow packet and a data flow migration policy. In this way, the silent time is used, a newly arrived data flow is redirected, and the newly arrived data flow is directly sent to the target virtual machine according to the data flow migration policy, which avoids migration of the newly arrived data flow. Therefore, data flows that arrive at the source virtual machine are on the decrease, and system migration performance is effectively improved.
