Abstract: This application discloses a communications method and related communications apparatus and system. The method includes recovering, by a first node, when detecting that a first packet is lost, the first packet according to a local recovery mechanism. The first packet is a packet obtained based on a packet sent by at least one first terminal to at least one second terminal, and the first node is a node on a network path between each first terminal and a second terminal communicating with the first terminal. The method further includes adding a first identification information related to local recovery, and sending the first packet. This application can reduce a transmission delay and improve transmission efficiency.

Abstract: This application provides a sequence number synchronization method. The specific method includes: A first network device sends a data packet including a first synchronization indication to a second network device, where the first synchronization indication is used to indicate the second network device and the first network device to perform a sequence number synchronization operation. The first network device receives a response packet sent by the second network device, where the response packet includes a second synchronization indication, and the second synchronization indication is used to indicate that the second network device has received the packet including the first synchronization indication.

Abstract: This application discloses a queue control method and apparatus. The queue control method includes: A first device obtains a packet drop parameter of a first queue, where the packet drop parameter of the first queue is determined based on a packet that is dropped because the packet cannot be added to the first queue; and when the packet drop parameter of the first queue is greater than a first packet drop threshold, the first device increases a first cache parameter, where the first cache parameter is for adjusting a queue threshold of the first queue, and the queue threshold of the first queue indicates a maximum total quantity of bytes of packets that are allowed to be cached in the first queue.

Abstract: The present disclosure relates to methods and devices for obtaining path information of a data packet. One example method includes receiving, by a network device, a data packet transmitted in a network, and obtaining, by the network device, path information of the data packet from a source end to a destination end, where the path information is a total hop count of routers passed through by the data packet from the source end to the destination end or a latency of the data packet from the source end to the destination end.

Abstract: This application provides a network device service quality detection method and apparatus. A service function feature of a network device is built into a service template as a fixed part. An operation and maintenance engineer does not need to learn of a service function feature of each network device, and only needs to provide information such as a flow identifier and deployment information that are of a to-be-detected service flow. A controller dynamically deploys a detection point according to the flow identifier and the deployment information of the service flow that are provided by the operation and maintenance engineer and the fixed part of the service template, so as to automatically detect service quality of a network device, and reduce operation and maintenance complexity and difficulties.
