This paper presents a placement abstraction layer (PAL) that provides a clear and simple northbound interface for using such algorithms while hiding their internal functionality and implementation. Through its southbound interface, PAL can connect to different back ends that evaluate the calculated placements, e.g., using simulations, emulations, or testbed approaches. As an example for such evaluation back ends, we introduce a novel placement emulation framework (PEF) that allows executing calculated placements using real, containerbased VNFs on real-world network topologies. In a case study, we show how PAL and PEF facilitate reusing and evaluating placement algorithms as well as validating their underlying models and performance claims. https://ris.uni-paderborn.de/download/6972/6973/preprint_ris.pdf application/pdfno IEEE2018Verona, Italy eng IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN 2018)10.1109/NFV-SDN.2018.8725795 @inproceedings{Schneider_Peuster_Karl_2018, title={A Generic Emulation Framework for Reusing and Evaluating VNF Placement Algorithms}, DOI={<a href="https://doi.org/10.1109/NFV-SDN.2018.8725795">10.1109/NFV-SDN.2018.8725795</a>}, booktitle={IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN 2018)}, publisher={IEEE}, author={Schneider, Stefan Balthasar and Peuster, Manuel and Karl, Holger}, year={2018} } Schneider SB, Peuster M, Karl H.
