Abstract: A method, a device, and a system for implementing service path detection are provided. The method is applied to an SRv6 network, and includes: A first network device generates a first packet based on IPv6 and sends the first packet to a second network device, where the first packet includes a first indication and identification information of a service, and the first indication indicates that the first packet is a detection packet; and after receiving the first packet, the second network device detects, based on the first indication and the identification information of the service, a path for carrying the service.

Abstract: A broadband connection method includes a virtual broadband network gateway (vBNG)-control plane (CP) that receives first indication information from a user plane selection function (USF), where the first indication information indicates a second vBNG-user plane (UP) that replaces a first vBNG-UP when the first vBNG-UP is faulty. The vBNG-CP sends a user entry to the second vBNG-UP based on the first indication information, where the user entry is used by the second vBNG-UP to enable a user to access a network based on the user entry when the first vBNG-UP is faulty such that when a user plane is faulty, broadband access of a user is not interrupted, and the user can continue to access a network.

Abstract: Embodiments of this application provide a packet transmission method, apparatus, and system. A first network device sends a probe packet to a second network device, the probe packet includes an identifier of the first network device, and the identifier of the first network device is used to indicate the second network device to add the identifier of the first network device to a destination address in a response packet of the probe packet; and receives the response packet from the second network device, where the destination address in the response packet is the identifier of the first network device; or receives an updated response packet from a third network device, where a destination address in the updated response packet is the identifier of the first network device. Both the third network device and the first network device are connected to a same user-side network device.

Abstract: The present application discloses a congestion control method and an apparatus. The method includes: receiving, by a root node network element, a first link notification message; determining, based on the link status information of the first link, that the first link is congested; determining an identifier of a first leaf node network element based on a correspondence between an identifier of the first port and the identifier of the first leaf node network element; determining a service queue of the first leaf node network element based on a correspondence between the identifier of the first leaf node network element and an identifier of the service queue of the first leaf node network element; and lowering output bandwidth of the service queue of the first leaf node network element.
