In this paper, we propose JASPER, a fully automated approach to jointly optimizing scaling, placement, and routing for complex network services, consisting of multiple (virtualized) components. JASPER handles multiple network services that share the same substrate network; services can be dynamically added or removed and dynamic workload changes are handled. Our approach lets service designers specify their services on a high level of abstraction using service templates. JASPER automatically makes scaling, placement and routing decisions, enabling quick reaction to changes. We formalize the problem, analyze its complexity, and develop two algorithms to solve it. Extensive empirical results show the applicability and effectiveness of the proposed approach."}],"date_created":"2018-06-11T06:55:05Z","author":[{"id":"31764","first_name":"Sevil","last_name":"Dräxler","full_name":"Dräxler, Sevil"},{"last_name":"Karl","full_name":"Karl, Holger","id":"126","first_name":"Holger"},{"first_name":"Zoltan Adam","full_name":"Mann, Zoltan Adam","last_name":"Mann"}],"title":"JASPER: Joint Optimization of Scaling, Placement, and Routing of Virtual Network Services","type":"journal_article","_id":"3152","file":[{"file_size":1767054,"creator":"ups","access_level":"closed","date_updated":"2018-11-02T15:25:49Z","content_type":"application/pdf","file_name":"08382313.pdf","date_created":"2018-11-02T15:25:49Z","relation":"main_file","file_id":"5302","success":1},{"creator":"sevilmeh","file_size":2878350,"date_updated":"2019-01-21T16:12:36Z","access_level":"open_access","date_created":"2019-01-21T16:12:36Z","content_type":"application/pdf","file_name":"TNSM2846572_RIS.pdf","relation":"main_file","file_id":"6950"}],"doi":"10.1109/TNSM.2018.2846572","ddc":["000"],"urn":"31522","language":[{"iso":"eng"}],"year":"2018","has_accepted_license":"1"}
