Abstract: A network device management method and apparatus are provided. The method includes: generating statistical traffic data, where the statistical traffic data includes at least one of data traffic of a port of a network device, a queue status of the network device, traffic of a data packet that passes through the network device, or traffic of a target data flow that passes through the network device; and sending the statistical traffic data to a controller. The controller receives statistical traffic data sent by multiple network devices, and can adjust a path of a data flow dynamically according to a traffic status of each port of the multiple network devices or a traffic status of a transmitted data flow in the multiple network devices and by changing routing tables of the network devices, thereby improving link utilization, and further improving network performance.

Abstract: A forwarding table generation method is provided. The method includes: determining, by a forwarding device, a first timeslot set, where the first timeslot set includes multiple timeslots during which the forwarding device sends, to a first device by using a first flexible Ethernet group, multiple encoded data blocks generated by a physical coding sublayer; determining, by the forwarding device, a second timeslot set, where the second timeslot set includes multiple timeslots during which the forwarding device receives, by using a second FlexE group, the multiple encoded data blocks sent by a second device; and generating, by the forwarding device, a forwarding table, where the forwarding table includes a mapping relationship between the second FlexE group and the multiple timeslots included in the second timeslot set, and between the first FlexE group and the multiple timeslots included in the first timeslot set.

Abstract: The application provides a method: for any network node in a network, the network node may collect a traffic count result of traffic from the network node to a destination network node that belongs to a same area as the network node. Because destination network nodes of the network node are used to indicate an egress node on a path for forwarding a packet by the network node in the area, a control node may learn of, based on count results corresponding to the destination network nodes, traffic transmitted from the network node to egress nodes. This facilitates the control node to determine a traffic distribution feature in the network. The application provides a method that network nodes collect local aggregated traffic statuses, and then the control node determines the traffic distribution feature in the network based on the local aggregated traffic statuses collected by the network nodes.
