Abstract: A method for detecting loop position in an Ethernet network, includes: the Ethernet switch device learns a MAC address; in a MAC table, a first MAC address corresponds to a first port before the leaning of MAC address, and the first MAC address corresponds to a second port after the learning of MAC address; if the second port and the first port do not belong to the same sub-network, an interval between a time of learning on the second port and a time of transmitting a last packet or receiving a last packet from the first port is calculated; and if the interval is smaller than a predetermined judgment threshold of host migration, it is determined that a loop exists in a sub-network connected to the second port.

Abstract translation: 一种用于检测以太网中循环位置的方法，包括：以太网交换设备学习MAC地址; 在MAC表中，第一MAC地址对应于MAC地址倾斜之前的第一端口，并且在学习MAC地址之后第一MAC地址对应于第二端口; 如果第二端口和第一端口不属于同一子网，则计算第二端口上的学习时间与发送最后一个分组的时间或从第一端口接收最后一个分组的时间间隔; 并且如果间隔小于主机迁移的预定判定阈值，则确定在连接到第二端口的子网中存在循环。

Abstract: Embodiments of the present invention disclose a virtual network device. The virtual network device is configured to implement a broadband network gateway BNG function, and the virtual network device includes a load balance unit and a first forwarding unit; the load balance unit is configured to: receive a first data packet from a first user terminal, determine the first forwarding unit according to the first data packet and a first correspondence, and send the first data packet to the first forwarding unit, where the first correspondence indicates mapping from the first user terminal to the first forwarding unit; and the first forwarding unit is configured to receive and forward the first data packet. In addition, the embodiments of the present invention further disclose a method for implementing load sharing in a virtual network device.
