This application provides an optical power commissioning method, a commissioning system, a control device, and a commissioning station. The commissioning system includes a control device and one or more commissioning stations. The method includes the control device first identifies one or more to-be-commissioned services on which optical power commissioning needs to be performed, the control device sends, based on the to-be-commissioned service, commissioning information to the one or more commissioning stations on which the to-be-commissioned service passes through, where the one or more commissioning stations perform parallel optical power commissioning based on the commissioning information, and the one or more commissioning stations perform optical power commissioning based on the commissioning information. According to this application, a plurality of services and a plurality of commissioning stations can be commissioned concurrently.

Optical power commissioning method, commissioning system, control device, and commissioning station

In accordance with an embodiment, a method includes generating, by a network device, a flow table comprising a plurality of flow records; determining, by the network device, whether a data flow corresponding to the plurality of flow records is an abnormal flow; and sending, by the network device, a flow record of the abnormal flow to an analyzer in response to a determination that the data flow is the abnormal flow, so that the analyzer analyzes the abnormal flow.

Flow table sending method and related apparatus

A SDN orchestration method includes: obtaining a first request for creating a first logical switch; creating a control plane instance of the first logical switch, and sending first configuration information to instruct the first forwarding device to configure the data plane instance of the first logical switch; obtaining a second request for connecting the first logical switch to a first logical router; sending second configuration information to instruct the first forwarding device to configure a first port of the data plane instance of the first logical switch to be communicatively connected to a second port of a data plane instance of the first logical router on the second forwarding device configured with the data plane instance of the first logical router; and sending third configuration information to instruct the second forwarding device to configure the second port to be communicatively connected to the first port.
