Substantial efforts have been invested in the recent years in the development of new network management approaches taking advantage of emerging paradigms such as software-defined networking and network function virtualization. Until now however there has not been much progress in the development of a northbound interface (NBI) linking high-level requirements (HLRs) capturing business objectives to management operations. This is a crucial functionality to facilitate faster service deployment and realization of business objectives. In this paper we extend the efforts towards the development of a NBI and propose a novel approach for the automatic decomposition of HLRs to network management operations. We demonstrate its functionality based on representative use cases and evaluate its feasibility through prototype implementation. The results obtained show that our solution can translate new technical requirements to network configurations in the order of a few seconds, thus enabling the management of network functionality and services in short timescales. date: 2018-12-24 date_type: published publisher: IEEE official_url: https://ieeexplore.ieee.org/document/8584931 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1629471 isbn_13: 9783903176140 lyricists_name: Charalambides, Marinos lyricists_name: Pavlou, George lyricists_name: Tangari, Gioacchino lyricists_id: MCHAR90 lyricists_id: GPAVL62 lyricists_id: GTANG64 actors_name: Pavlou, George actors_id: GPAVL62 actors_role: owner full_text_status: public publication: 14th International Conference on Network and Service Management, CNSM 2018 and Workshops, 1st International Workshop on High-Precision Networks Operations and Control, HiPNet 2018 and 1st Workshop on Segment Routing and Service Function Chaining, SR+SFC 2 place_of_pub: Rome, Italy pagerange: 99-107 event_title: 2018 14th International Conference on Network and Service Management (CNSM) citation: Tuncer, D; Charalambides, M; Tangari, G; Pavlou, G; (2018) A Northbound Interface for Software-based Networks.
