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.","lang":"eng"}],"publication":"4th IEEE International Conference on Network Softwarization (NetSoft 2018)","type":"conference","department":[{"_id":"75"}],"file":[{"date_updated":"2018-12-12T15:18:12Z","relation":"main_file","access_level":"closed","file_size":2211450,"file_name":"08460029.pdf","content_type":"application/pdf","success":1,"file_id":"6195","creator":"ups","date_created":"2018-12-12T15:18:12Z"},{"file_id":"6968","content_type":"application/pdf","file_name":"NetSoft18_RIS.pdf","file_size":3445650,"access_level":"open_access","relation":"main_file","date_updated":"2019-01-24T10:17:00Z","date_created":"2019-01-24T10:17:00Z","creator":"sevilmeh"}],"date_created":"2018-04-24T12:11:36Z","date_updated":"2022-01-06T06:56:37Z","title":"Generating Resource and Performance Models for Service Function Chains: The Video Streaming Case","year":"2018","author":[{"last_name":"Dräxler","first_name":"Sevil","full_name":"Dräxler, Sevil","id":"31764"},{"full_name":"Peuster, Manuel","last_name":"Peuster","first_name":"Manuel","id":"13271"},{"first_name":"Marvin","last_name":"Illian","full_name":"Illian, Marvin"},{"id":"126","full_name":"Karl, Holger","first_name":"Holger","last_name":"Karl"}],"doi":"10.1109/NETSOFT.2018.8460029","language":[{"iso":"eng"}]},{"abstract":[{"lang":"eng","text":"Network function virtualization requires scaling and placement, deciding the number and the location of function instances.

We develop models to support stateful components and legacy network functions with fixed locations in these network services as well as the possibility of reusing VNFs across network services. We formalize the problem of jointly scaling and placing such network services as a mixed- integer linear program (MILP).

This becomes par- ticular challenging when stateful functions are involved, necessi- tating state management. The problem with existing solutions is that they typically embrace state migration and flow rerouting jointly, imposing a huge set of requirements on the on-boarded VNFs, e.g., solution-specific state management interfaces.\r\nIn this paper, we introduce the seamless handover proto- col (SHarP). It provides an easy-to-use, loss-less, and order- preserving flow rerouting mechanism that is not fixed to a single state management approach. This allows VNF vendors to implement or use the state management solution of their choice. SHarP supports these solutions with additional information when flows are migrated. Further, we show how SHarP significantly reduces the buffer usage at a central (SDN) controller, which is a typical bottleneck in existing solutions. Our experiments show that SHarP uses a constant amount of controller buffer, irrespective of the time taken to migrate the VNF state.","lang":"eng"}],"publication":"4th IEEE International Conference on Network Softwarization (NetSoft 2018)","department":[{"_id":"75"}],"type":"conference","date_created":"2018-06-25T12:21:49Z","file":[{"creator":"peuster","date_created":"2018-07-05T11:11:37Z","date_updated":"2018-07-05T11:12:29Z","relation":"main_file","file_size":901561,"access_level":"open_access","file_name":"main_ris.pdf","content_type":"application/pdf","file_id":"3428"}],"has_accepted_license":"1","conference":{"name":"4th IEEE International Conference on Network Softwarization (NetSoft 2018)","start_date":"2018-06-25","location":"Montreal","end_date":"2018-06-29"},"status":"public","ddc":["000"],"user_id":"13271","urn":"33458","_id":"3345","project":[{"name":"5G Development and validation platform for global industry-specific network services and Apps","grant_number":"761493","_id":"28"},{"name":"SFB 901","_id":"1"},{"_id":"4","name":"SFB 901 - Project Area C"},{"name":"SFB 901 - Subproject C4","_id":"16"}],"citation":{"mla":"Peuster, Manuel, et al. “ Let the State Follow Its Flows: An SDN-Based Flow Handover Protocol to Support State Migration.” <i>4th IEEE International Conference on Network Softwarization (NetSoft 2018)</i>, doi:<a href=\"https://doi.org/10.1109/NETSOFT.2018.8460007\">10.1109/NETSOFT.2018.8460007</a>.","bibtex":"@inproceedings{Peuster_Küttner_Karl, place={Montreal}, title={ Let the state follow its flows: An SDN-based flow handover protocol to support state migration}, DOI={<a href=\"https://doi.org/10.1109/NETSOFT.2018.8460007\">10.1109/NETSOFT.2018.8460007</a>}, booktitle={4th IEEE International Conference on Network Softwarization (NetSoft 2018)}, author={Peuster, Manuel and Küttner, Hannes and Karl, Holger} }","ama":"Peuster M, Küttner H, Karl H.

This task becomes very challenging because large-scale NFV testbeds are hard to maintain, too expensive, or simply not available.\r\n\r\nIn this paper, we present a multi-PoP NFV infrastructure emulation platform that enables automated, large-scale testing of MANO stacks. We show that our platform can easily emulate hundreds of PoPs on a single physical machine and reduces the setup time of a test PoP by a factor of 232x compared to a DevStack-based test PoP installation.

In this paper, we propose JASPER, a fully automated approach to jointly optimizing scaling, placement, and routing for complex network services, consisting of multiple (virtualized) components. JASPER handles multiple network services that share the same substrate network; services can be dynamically added or removed and dynamic workload changes are handled. Our approach lets service designers specify their services on a high level of abstraction using service templates. JASPER automatically makes scaling, placement and routing decisions, enabling quick reaction to changes. We formalize the problem, analyze its complexity, and develop two algorithms to solve it. Extensive empirical results show the applicability and effectiveness of the proposed approach."}],"_id":"3152","publisher":"IEEE","urn":"31522","ddc":["000"],"user_id":"31764","status":"public","has_accepted_license":"1","oa":"1","citation":{"ama":"Dräxler S, Karl H, Mann ZA.

Currently, development requires many manual\r\nsteps that are time-consuming and error-prone (e.g., for creating\r\nservice descriptors). Furthermore, existing management and\r\norchestration (MANO) platforms only offer limited support of\r\nstandardized descriptor models or package formats, limiting the\r\nre-usability of network services.\r\n\r\nTo this end, we introduce a fully integrated, open-source\r\nNFV service development kit (SDK) with multi-MANO platform\r\nsupport. Our SDK simplifies many NFV service development\r\nsteps by offering initial generation of descriptors, advanced\r\nproject management, as well as fully automated packaging and\r\nsubmission for on-boarding. To achieve multi-platform support,\r\nwe present a package format that extends ETSI’s VNF package\r\nformat. In this demonstration, we present the end-to-end workflow\r\nto develop an NFV service that is then packaged for multiple\r\nplatforms, i.e., 5GTANGO and OSM.","lang":"eng"}],"main_file_link":[{"url":"https://ieeexplore.ieee.org/abstract/document/8725794"}],"language":[{"iso":"eng"}],"doi":"10.1109/NFV-SDN.2018.8725794","year":"2018","title":"A Fully Integrated Multi-Platform NFV SDK","author":[{"id":"35343","orcid":"0000-0001-8210-4011","last_name":"Schneider","first_name":"Stefan Balthasar","full_name":"Schneider, Stefan Balthasar"},{"id":"13271","last_name":"Peuster","first_name":"Manuel","full_name":"Peuster, Manuel"},{"full_name":"Tavernier, Wouter","last_name":"Tavernier","first_name":"Wouter"},{"full_name":"Karl, Holger","last_name":"Karl","first_name":"Holger","id":"126"}],"date_updated":"2022-01-06T07:03:25Z"},{"publisher":"Universität Paderborn","_id":"1208","language":[{"iso":"eng"}],"doi":"10.17619/UNIPB/1-287","user_id":"477","year":"2018","title":"Data-Centre Traffic Optimisation using Software-Defined Networks","status":"public","author":[{"full_name":"Schwabe, Arne","first_name":"Arne","last_name":"Schwabe"}],"date_updated":"2022-01-06T06:51:17Z","date_created":"2018-03-13T10:22:51Z","type":"dissertation","department":[{"_id":"75"}],"supervisor":[{"last_name":"Karl","first_name":"Holger","full_name":"Karl, Holger","id":"126"}],"citation":{"mla":"Schwabe, Arne. <i>Data-Centre Traffic Optimisation Using Software-Defined Networks</i>.
