This becomes even more challenging when agile development methodologies, like DevOps, are applied. In such scenarios, management and orchestration systems are continuously facing new versions of functions and services which makes it hard to decide how much resources have to be allocated to them to provide the expected service performance. \r\nOne solution for this problem is to support resource allocation decisions with performance behavior information obtained by profiling techniques applied to such network functions and services.\r\n\r\nIn this position paper, we analyze and discuss the components needed to generate such performance behavior information within the NFV DevOps workflow. We also outline research questions that identify open issues and missing pieces for a fully integrated NFV profiling solution. Further, we introduce a novel profiling mechanism that is able to profile virtualized network functions and entire network service chains under different resource constraints before they are deployed on production infrastructure."}],"has_accepted_license":"1","project":[{"name":"SONATA NFV: Agile Service Development and Orchestration in 5G Virtualized Networks","call_identifier":"5G PPP Phase 1","grant_number":"671517","_id":"25"},{"name":"SFB 901","_id":"1"},{"_id":"4","name":"SFB 901 - Project Area C"},{"name":"SFB 901 - Subproject C4","_id":"16"}],"page":"7--12","file":[{"file_size":966702,"creator":"peuster","date_created":"2018-06-25T13:10:10Z","date_updated":"2018-06-25T13:16:56Z","relation":"main_file","content_type":"application/pdf","access_level":"open_access","file_name":"main_ris.pdf","file_id":"3353"}],"doi":"10.1109/EWSDN.2016.9","publication_status":"published","ddc":["000"],"citation":{"chicago":"Peuster, Manuel, and Holger Karl. “Understand Your Chains: Towards Performance Profile-Based Network Service Management.” In <i>Fifth European Workshop on Software-Defined Networks, EWSDN 2016, Den Haag, The Netherlands, October 10-11, 2016</i>, 7--12, 2016. <a href=\"https://doi.org/10.1109/EWSDN.2016.9\">https://doi.org/10.1109/EWSDN.2016.9</a>.","short":"M.
