Abstract: A method for obtaining path association information, a device, and a system are provided, and belong to the field of network technologies. A first network device generates a packet carrying template indication information, and sends the packet to a second network device. After receiving the packet, the second network device determines, based on the template indication information carried in the packet, a target template associated with a target forwarding path, and performs, based on the target template, an operation associated with the target forwarding path. In this way, the first network device may include template indication information corresponding to different templates in a packet, to indicate different receiving network devices to determine a target template associated with a target forwarding path, and determine, based on the target template, association information such as a path attribute or a path constraint associated with the target forwarding path. The path association information is advertised in a manner of carrying the template indication information provided in this method, so that flexibility of obtaining the path association information can be improved without affecting protocol stability.

Abstract: A service processing method includes that a first network device determines a second network device on a forwarding path of a packet based on a service requirement; the first network device sends a first message to the second network device, to establish a first connection to the second network device; and the first network device sends a second message to the second network device using the first connection, where the second message requests the second network device to assist in determining information related to the forwarding path. when determining the second network device is needed to assist the first network device for information related to the forwarding path of the packet, the first network device actively establishes a connection to the second network device, and requests, using the established connection, the second network device to assist the first network device in determining the information related to the forwarding path.
