Abstract: The technology of this application relates to a transmission control method and apparatus. The method includes obtaining traffic information of a first node at M sample moments, where M is a positive integer greater than or equal to 1, determining first traffic information of the first node at a first moment based on the traffic information of the first node at the M sample moments, where the first moment does not belong to the M sample moments, determining first rate-limited traffic based on the first traffic information, where the first rate-limited traffic indicates maximum traffic that is allowed to pass through a first queue of the first node at the first moment, and limiting traffic of the first queue at the first moment based on the first rate-limited traffic.

Abstract: This application discloses a cloud platform selection method and apparatus. The method includes: obtaining service information, where the service information includes access device information and path requirement information; obtaining a recommendation result of a cloud platform based on the service information, where the recommendation result indicates a cloud platform corresponding to each access device in a first device set, the first device set includes a first access device, the first access device corresponds to a first cloud platform, path requirement evaluation information of a path from the first access device to the first cloud platform meets the path requirement information, the first device set includes M access devices or a part of the M access devices, the cloud platform corresponding to each access device belongs to a candidate cloud platform set, and the candidate cloud platform set includes P cloud platforms; and displaying the recommendation result in a first interface.

Abstract: A communication method, device, and system are disclosed, and pertain to the field of communication technologies. The method includes: After determining a node set including a node that supports segment routing, a controller may send a target segment identifier list to a source node, to indicate the source node to forward a packet of a target flow based on the target segment identifier list, where the source node of the target flow in a communication network belongs to the node set. According to the communication method provided in this application, the target segment identifier list can be sent to the source node of the target flow, to indicate a packet forwarding path of the target flow, thereby reducing network link congestion, and improving packet forwarding efficiency.

Abstract: A monitoring circuit includes: a sampling module, configured to sample an initial address to obtain a monitoring address; a counting module, configured to adjust a counting value of a first counter corresponding to the monitoring address and set a predetermined value for the monitoring address, and a magnitude of the set predetermined value is positively correlated with duration for which the monitoring address is stored in the counting module; and a processing module, configured to compare the counting value of the first counter corresponding to each monitoring address with the predetermined value, where if the counting value of the first counter is greater than or equal to the predetermined value, the monitoring address is retained, and if the counting value of the first counter is less than the predetermined value, the monitoring address is released, and the first counter and the predetermined value corresponding to the monitoring address are reset.
