--- res: bibo_abstract: - "Benchmarking and profiling virtual network functions (VNFs) generates input\r\nknowledge for resource management decisions taken by \r\nmanagement and orchestration systems. \r\nSuch VNFs are usually not executed in isolation but are often deployed as part of a service function chain (SFC) that connects single functions into complex \r\nstructures. To manage such chains, isolated performance\r\nprofiles of single functions have to be combined to get insights into \r\nthe overall behavior of an SFC. This becomes particularly\r\nchallenging in highly agile DevOps environments in which profiling\r\nprocesses need to be fully automated and detailed insights about a chain's\r\ninternal structures are not always available. \r\n\r\nIn this paper, we introduce a\r\nfully automatable, flexible, and platform-agnostic profiling\r\nsystem that allows to profile entire SFCs at once. This obviates \r\nmanual modeling procedures to combine profiling results from single\r\nVNFs to reflect SFC performance. \r\nWe use a case study with different SFC configurations to show that it\r\nis hard to model the resulting SFC performance based on single-VNF measurements and that\r\nperformance interactions between real, non-trivial functions that are deployed in a\r\nchain exist. @eng" bibo_authorlist: - foaf_Person: foaf_givenName: Manuel foaf_name: Peuster, Manuel foaf_surname: Peuster foaf_workInfoHomepage: http://www.librecat.org/personId=13271 - foaf_Person: foaf_givenName: Holger foaf_name: Karl, Holger foaf_surname: Karl foaf_workInfoHomepage: http://www.librecat.org/personId=126 bibo_doi: 10.1109/NFV-SDN.2017.8169826 dct_date: 2017^xs_gYear dct_language: eng dct_title: Profile Your Chains, Not Functions.
