AB The 5G-TRANSFORMER project proposes an NFV/SDN-based architecture to manage the end-to-end deployment of composite NFV network services, which may involve multiple administrative domains, hence, requiring network service federation capabilities. At the architectural level, this article presents the service federation functionality of the 5G-TRANSFORMER service orchestrator. It covers the gaps identified in ETSI NFV reports and specifications (e.g., IFA028). Some recommendations are also presented based on this experience, particularly on the relevance of multi-domain resource orchestration. Experimental results show that the federated service under evaluation is deployed in less than 5 minutes. Time profiling of the various processing federation-related operation shows its reduced impact in the experienced deployment time. A comparison of service deployments of increasing complexity also offers valuable insights.
