Abstract: In embodiments of this application, the network node may receive a first data packet, where the first data packet carries first traffic feature data of a first data flow to which the first data packet belongs. The network node may determine a data forwarding policy based on the first traffic feature data. Because the data forwarding policy includes a policy used when the network node forwards a data packet included in the first data flow, the network node may forward the data packet based on the data forwarding policy. It may be learned that, in this solution, there is no need for a controller to determine the forwarding policy and the network node to execute the forwarding policy. Instead, the network node may learn of the traffic feature data of the transmitted data flow in real time, and determine and use the data forwarding policy in a timely manner.

Abstract: Embodiments of this application disclose a packet processing method and a related device, which may be applied to a mobile communications network. A first network device generates a first packet, where a packet header of the first packet carries application information; the first network device sends the first packet to a second network device; and the second network device provides a network service based on the application information in the packet header of the first packet. Because the second network device can identify the application information in the packet header of the first packet, and provide the corresponding network service based on the application information, differentiated network services are implemented, and a fine granularity of the network services is improved.

Abstract: Embodiments of this application disclose an application layer traffic optimization ALTO protocol-based communication method and a related apparatus. The method includes: An ALTO server sends first information to an ALTO client according to an ALTO protocol, where the first information indicates one or more network services available in a first network, and the first information is used by a first device associated with the ALTO client to obtain the one or more network services. In embodiments of this application, a network service allocation (or network service exposure) interface is provided according to the ALTO protocol. This improves efficiency of system interconnection between an operator and a service provider, reduces difficulty in exposing a network service by the operator, reduces difficulty of network service rollout, and improves timeliness of network service rollout.

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: A packet forwarding method, apparatus, and system, and a computer-readable storage medium are disclosed, and pertain to the field of communication technologies. After receiving a packet sent by a second device, a first device determines a target service node based on indication information and an application service identifier that are in the packet, where a service capability of the target service node matches the indication information, and a target application service corresponding to the application service identifier is deployed in the target service node. Then, the first device sends the packet to the target service node. The indication information is carried in the packet sent by the device, so that a forwarding device can send the packet to a service node whose service capability matches the indication information. In this way, differentiated application services are provided for devices of different levels, and flexibility of task scheduling is high.

Abstract: Embodiments of this application disclose a packet processing method and a related device. When determining a first network resource based on dynamic information, a network device performs in-band flow measurement in a network domain in which the first network resource is used, to detect actual transmission quality of a packet of an application in the network domain. By comprehensively considering dynamic information, of the application, used when the packet of the application is forwarded by using the first network resource and a detection result of in-band flow measurement in the network domain, the network device obtains a second network resource for forwarding a packet of the application, and forwards a subsequent packet of the application for the application in the network domain by using the second network resource.
