This paper presents the design of the 5GT Service Orchestrator (SO), which is one of the key components of the 5GTRANSFORMER (5GT) system for the deployment of vertical services. Depending on the requests from verticals, the 5GT-SO offers service or resource orchestration and federation. These functions include all tasks related to coordinating and providing the vertical with an integrated view of services and resources from multiple administrative domains. In particular, service orchestration entails managing end-to-end services that are split into various domains based on requirements and availability. Federation entails managing administrative relations at the interface between the SOs belonging to different domains and handling abstraction of services. The SO key functionalities, architecture, interfaces, as well as two sample use cases for service federation and service and resource orchestration are presented. Results for the latter use case show that a vertical service is deployed in the order of minutes.
