Abstract: A traffic detection method, apparatus, and system are provided. A first network device obtains a packet, where the packet is any packet of the traffic. The first network device adds a detection flag and detection indication information to the packet to update the packet, where the detection flag is used to indicate a position of the detection indication information, where the detection indication information includes a first flag, and the first flag is used to indicate whether the traffic is to-be-detected traffic. The first network device sends an updated packet to a second network device. According to this method, traffic performance is detected, and flexibility and extensiveness of traffic performance detection are improved.

Abstract: An in-situ flow detection method. When determining a transmission delay in a detection domain in a first in-situ flow detection period, a first network node may color a plurality of packets in a first service flow that are received by the first network node through a first inbound interface and determine the delay in the detection domain in the first in-situ flow detection period based on the plurality of colored packets, thereby improving the precision of the detected transmission delay in the detection domain.

Abstract: A method for configuring performance measurement indication information and a related device. The method includes: a control node determines performance measurement indication information and sends a first advertisement packet in the communication network based on the BGP, where the first advertisement packet carries the performance measurement indication information, so that a plurality of forwarding nodes configure the performance measurement indication information on the plurality of forwarding nodes. In this way, when a data flow on which performance measurement is to be performed is transmitted between a plurality of different ASs, each forwarding node in the different ASs may obtain the performance measurement indication information from the first advertisement packet.

Abstract: A packet forwarding method and apparatus, and a communication network, related to the field of communication technologies. In the solutions provided, a controller may obtain a correspondence between an application-aware identifier of a service flow and a network service required for transmitting the service flow, and deliver the correspondence to a network device. Further, when identifying the service flow as a service flow indicated by the application-aware identifier, the network device may directly forward a packet of the service flow by using the corresponding network service. The controller may establish and deliver the correspondence between the application-aware identifier and the network service, so that the network device can directly forward the service packet of the service flow based on the correspondence. Therefore, flexibility of forwarding the service packet is effectively improved.

Abstract: Embodiments of this application provide a packet sending method and a device, to improve packet transmission efficiency. The method includes: A first network device receives a first packet from a second network device, where the first packet includes information about a first forwarding path, and the first forwarding path is a forwarding path for sending the first packet from the second network device to the first network device. The first network device obtains information about a second forwarding path based on the information about the first forwarding path, where the second forwarding path is a reverse path of the first forwarding path. The first network device sends a second packet to the second network device through the second forwarding path, where the second packet carries the information about the second forwarding path.

Abstract: A network performance detection method and apparatus, and a related network device are disclosed. According to the network performance detection method, a first IFIT header includes reporting manner indication information indicating that reporting is performed by an egress node device. After obtaining a first IFIT detection packet including the first IFIT header, a first network device can provide and process a second IFIT detection packet, where the second IFIT detection packet is obtained by adding a first device identifier and a first data flow detection result to the first IFIT detection packet. In other words, a detection result obtained by detecting a first data flow is reported only by the egress node device, and all node devices on a transmission link of the first data flow each includes the detection result in a same IFIT detection packet and sends the same IFIT detection packet to the egress node device.
