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 controller is configured to obtain traffic information of one or more tunnels in the network, where the traffic information of each tunnel is indicative of a protection type of the tunnel against failures, and provide configuration information to each network node that is a head-end node of a determined tunnel with a certain protection type according to the obtained traffic information of the determined tunnel, where the configuration information includes a bandwidth threshold and a load balancing configuration for the determined tunnel. A network node is configured to receive configuration information from the controller, and send the notification to the controller, if it is determined that the traffic of the tunnel is above the bandwidth threshold.

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.
