For this purpose and for practical research in network function virtualization in general, there is a great need for benchmarks and experimental data. In this paper, we describe our experiments for characterizing the relationship between resource demands of virtual network functions (VNFs) and the expected performance of the SFC, considering the individual performance of the VNFs as well as the interdependencies among VNFs within the SFC. We have designed our experiments focusing on video streaming, an important application in this context. We present examples of models for predicting the interdependence between resource demands and performance characteristics of SFCs using support vector regression and polynomial regression models. We also show practical evidence from our experiments that VNFs need to be benchmarked in their final chain setup, rather than individually, to capture important interdependencies that affect their performance. The data gathered from our experiments is publicly available. https://ris.uni-paderborn.de/download/2480/6195/08460029.pdf application/pdf https://ris.uni-paderborn.de/download/2480/6968/NetSoft18_RIS.pdf application/pdfno IEEE2018Montreal eng 4th IEEE International Conference on Network Softwarization (NetSoft 2018)10.1109/NETSOFT.2018.8460029 318--322 S.
