    摘要： Embodiments of the present invention provide a method for establishing a service path in a transport network, a network device, and a system, and the service path passes through an automatically switched optical network ASON and at least one edge network. The method includes: An ASON first node obtains a service path computation result path, where the service path includes the ASON first node, an ASON last node, and at least one first edge network node; the ASON first node sends a path establishment request message to a downstream node, where the path establishment request message carries cross-connection configuration information of the ASON last node and the at least one first edge network node; and the ASON first node receives a path establishment response message of the downstream node, where the path establishment response message indicates that cross-connection configuration for the ASON last node and the at least one first edge network node is complete. In the embodiments of the present invention, an end-to-end service path across the edge network and the ASON can be automatically configured, thereby improving service provisioning efficiency and accuracy.

    摘要： Embodiments of the present invention disclose a service troubleshooting method, apparatus, and device, and are related to the field of communications technologies, so as to resolve a problem that due to instability of a physical parameter of an optical layer network, a service is frequently switched between a working path and a protection path at an optical layer, and an IP layer node generates a false alarm, and consequently, the service is frequently switched between currently available paths, affecting transmission of another service and stability of a transmission network. The present invention is applied to a service transmission network including an IP layer network and an optional layer network. The IP layer network includes an IP layer PCE and an IP node. The IP layer PCE receives alarm details. The IP layer PCE determines a fault type of a service transmission path in the optical layer network according to the alarm details. The IP layer PCE performs service optimization when determining that the path fault type is a real fault. The IP layer PCE does not perform service optimization when determining that the path fault type is a pseudo fault.

    摘要： Embodiments of the present invention disclose a service optimization method, a transport controller, a client controller, and a service optimization system. The method includes: receiving, by a TC, an optimization request from a CC; sending, by the TC, an answer message to the CC when determining that an idle resource in a resource pool can meet an optimization requirement of the CC, where the answer message carries identification information of a service and an optimization policy that meets the optimization requirement of the CC; receiving, by the TC, an optimization instruction of the CC, where the optimization instruction carries the identification information of the service and a corresponding optimization policy that meets the optimization requirement of the CC; and optimizing, by the TC according to the optimization policy in the optimization instruction, the service identified in the optimization instruction. It can be learned that, in the embodiments of the present invention, the CC may send the optimization request to the TC, and when an idle network resource in the resource pool can meet the optimization requirement of the CC, the TC executes the optimization policy that meets the optimization requirement of the CC, so as to reduce a service interruption phenomenon in a service optimization process.
