Abstract: This application provides a node device implementing connection establishment for a Space Division Multiplexing (SDM) network. A first node receives a path (Path) message, which includes a plurality of label objects, each label object includes a field used to indicate a number of an optical core in a multi-core optical fiber, and idle spectrum information of each optical core. The first node then obtains an intersection set of the idle spectrum information of each optical core indicated in the path message and idle spectrum information of a corresponding optical core on a first link. The first node sends, over the first link, a path message that carries an intersection set result, where the first link is a link between the first node and an adjacent node in a direction from the first node to an end node.

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.
