In doing so, various optimization objectives are conceivable, e.g., minimizing certain required resources or the end-to-end delay of the placed services.\r\n\r\nIn this paper, we investigate the relationship between four typical optimization objectives when coordinating the placement and resource allocation of chained VNF instances. We observe an interesting trade-off between minimizing the overhead of starting/stopping VNF instances and all other objectives when adapting to changed service demands."}],"ddc":["040"],"year":"2018","conference":{"name":"IEEE Global Communications Conference (GLOBECOM 2018)","location":"Abu Dhabi, UAE"},"language":[{"iso":"eng"}],"_id":"6970","date_updated":"2022-01-06T07:03:24Z","author":[{"id":"35343","orcid":"0000-0001-8210-4011","first_name":"Stefan Balthasar","full_name":"Schneider, Stefan Balthasar","last_name":"Schneider"},{"first_name":"Sevil","id":"31764","last_name":"Dräxler","full_name":"Dräxler, Sevil"},{"first_name":"Holger","id":"126","last_name":"Karl","full_name":"Karl, Holger"}],"status":"public","has_accepted_license":"1","title":"Trade-offs in Dynamic Resource Allocation in Network Function Virtualization","date_created":"2019-01-24T13:53:22Z","publication":"IEEE Global Communications Conference (GLOBECOM 2018)","file_date_updated":"2019-01-24T13:53:16Z","type":"conference"}
