Abstract: A method, an apparatus, and a system for controlling access of a user terminal, where the method includes receiving, by a controller, an authentication packet sent by an access switching node through an established data tunnel; obtaining, by the controller, a source media access control (MAC) address of the authentication packet; after access authentication implemented on a user terminal, determining, from a maintained correspondence between MAC addresses of user terminals and interface identifiers, an interface identifier corresponding to the MAC address of the successfully-authenticated user terminal, where the interface identifier identifies an interface connected to the user terminal; and sending, by the controller, the determined interface identifier to the access switching node through an established control tunnel, and instructing the access switching node to enable the interface corresponding to the interface identifier.
Abstract translation: 一种用于控制用户终端访问的方法，装置和系统，其中所述方法包括由控制器通过建立的数据隧道接收由接入交换节点发送的认证分组; 由所述控制器获取所述认证包的源媒体访问控制（MAC）地址; 在用户终端上实现接入认证之后，从用户终端的MAC地址和接口标识符之间的维持的对应关系中确定与成功认证的用户终端的MAC地址对应的接口标识符，其中，接口标识符标识连接到 用户终端; 并且由所述控制器通过建立的控制隧道将所确定的接口标识符发送到所述接入交换节点，并且指示所述接入交换节点启用与所述接口标识符相对应的接口。

Abstract: The method includes: receiving, by a first device, a first packet from a second device, where the first packet includes a primary scheduling identifier, and the primary scheduling identifier is used to identify that the second device has permission to select a path; determining, by the first device, a first path used to transmit the first packet; sending, by the first device, a second packet to the second device by using the first path, where the second packet includes a following identifier, and the following identifier is used to identify that the first device sends the packet by using a transmission path selected by a device other than the first device. This can ensure that a same path is used for bidirectional packet transmission between two communication parties while ensuring service quality, in a complex SD-WAN path selection scenario.
