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.

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: A packet transmission method and an electronic device. In the packet transmission method, a response packet request field is set in a service packet, and a sending device can set a value of a response packet request field in a sent service packet. When the sending device needs a receiving device to send a response packet, the sending device changes a value of a response packet request field in a subsequently sent service packet, to trigger the receiving device to send the response packet to the sending device.

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: The present disclosure discloses a method for determining a Transmission Control Protocol (TCP) congestion window, and an apparatus. The communications method includes: receiving, by a network node, a data packet; obtaining a load level of a first output port used for sending the data packet by the network node; updating a load level in the data packet; and generating a network node data packet and sending the network node data packet to a TCP receive end. A TCP receiving end adds a load level to a to-be-returned acknowledgement (ACK) packet. A TCP transmitting end determines a new congestion window based on the load level of the ACK packet and a current congestion window.
