Abstract: This application relates to example service configuration methods and example apparatuses. In one example method, a first optical transport network (OTN) device receives a first message from an optical line terminal (OLT) device, where the first message includes first address information of a service. The first OTN device determines, based on the first message, whether a first path has been established in an OTN, where the first path is used to transmit data of the service, and the first path satisfies the first address information. The first OTN device establishes a path for transmitting data of the service or adjusts a bandwidth of the established first path based on a result of the determining.

Abstract: Embodiments can provide a service orchestration method and apparatus, and a server. In the service orchestration method, a service flowchart can be obtained. The service flowchart may include a plurality of operation model identifiers and a logical connection relationship among the plurality of operation model identifiers. The logical connection relationship may be an execution sequence in the service flowchart. In this method, a scheduling parameter corresponding to each operation model identifier can be obtained. When the scheduling parameter indicates a live network resource for executing the service flowchart, a live network status can be obtained by using a control plane. Based on the obtained live network status, whether the live network resource can be obtained can be verified. When the verification succeeds, based on the logical connection relationship and the scheduling parameter that corresponds to each operation model identifier, executable code for executing the service flowchart can be generated.
