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.

Abstract: A path identity allocation method, system, and apparatus, a device, and a storage medium are provided, and belong to the field of communication technologies. According to the method, a forwarding node on a path receives a PCEP packet, so that when determining that path identification information of the path is unavailable, the forwarding node performs, based on indication information in the PCEP packet, an operation associated with the path identification information, for example, determines, based on indicated content, that the forwarding node reallocates a path identity, or requests the control node to reallocate a path identity.
