However, as it is not feasible to realise all types of VNFs in CNs, the coexistence of VMs and CNs is proposed. To put VMs and CNs together, an orchestration framework that can chain services across distributed and heterogeneous domains is required. To this end, we implemented a framework by extending and consolidating state-of-the-art tools and technologies originated from Network Function Virtualization (NFV), Software-defined Networking (SDN) and cloud computing environments. This framework chains services provisioned across Kubernetes and OpenStack domains. During the demo, we deploy a service consist of CN- and VM-based VNFs to demonstrate different features provided by our framework.","lang":"eng"}],"file":[{"content_type":"application/pdf","relation":"main_file","date_updated":"2019-08-26T09:09:50Z","creator":"ups","date_created":"2019-08-26T09:09:50Z","file_size":1206037,"file_id":"12953","access_level":"closed","file_name":"p240-Kouchaksaraei.pdf"}],"publication":"13th ACM International Conference on Distributed and Event-based Systems","title":"Service Function Chaining Across OpenStack and Kubernetes Domains","date_created":"2019-05-14T05:43:57Z","year":"2019"},{"date_updated":"2022-01-06T07:04:23Z","oa":"1","author":[{"last_name":"Peuster","id":"13271","full_name":"Peuster, Manuel","first_name":"Manuel"},{"first_name":"Stefan Balthasar","id":"35343","full_name":"Schneider, Stefan Balthasar","last_name":"Schneider","orcid":"0000-0001-8210-4011"},{"full_name":"Zhao, Mengxuan","last_name":"Zhao","first_name":"Mengxuan"},{"full_name":"Xilouris, George","last_name":"Xilouris","first_name":"George"},{"last_name":"Trakadas","full_name":"Trakadas, Panagiotis","first_name":"Panagiotis"},{"first_name":"Felipe","full_name":"Vicens, Felipe","last_name":"Vicens"},{"first_name":"Wouter","full_name":"Tavernier, Wouter","last_name":"Tavernier"},{"first_name":"Thomas","full_name":"Soenen, Thomas","last_name":"Soenen"},{"last_name":"Vilalta","full_name":"Vilalta, Ricard","first_name":"Ricard"},{"last_name":"Andreou","full_name":"Andreou, George","first_name":"George"},{"last_name":"Kyriazis","full_name":"Kyriazis, Dimosthenis","first_name":"Dimosthenis"},{"last_name":"Karl","id":"126","full_name":"Karl, Holger","first_name":"Holger"}],"doi":"10.1109/mcom.2019.1800873","main_file_link":[{"url":"https://ieeexplore.ieee.org/document/8713807"}],"publication_identifier":{"issn":["0163-6804","1558-1896"]},"has_accepted_license":"1","publication_status":"published","page":"96-102","citation":{"ieee":"M.

These approaches depend not only on their program code to operate properly, but also require enough input data to train their internal models. However, such training data is barely available for the software networking domain and most presented solutions rely on their own, sometimes not even published, data sets. This makes it hard, or even infeasible, to reproduce and compare many of the existing solutions. As a result, it ultimately slows down the adoption of machine learning approaches in softwarised networks. To this end, we introduce the \"softwarised network data zoo\" (SNDZoo), an open collection of software networking data sets aiming to streamline and ease machine learning research in the software networking domain. We present a general methodology to collect, archive, and publish those data sets for use by other researches and, as an example, eight initial data sets, focusing on the performance of virtualised network functions.\r\n","lang":"eng"}],"publication":"IEEE/IFIP 15th International Conference on Network and Service Management (CNSM)","language":[{"iso":"eng"}],"ddc":["000"]},{"has_accepted_license":"1","citation":{"apa":"Moro, D., Peuster, M., Karl, H., &#38; Capone, A.

It becomes even harder if heterogeneous services, making use of different offloading and network virtualization technologies, should be developed.\r\nIn this paper, we introduce FOP4 (Function Offloading Pro- totyping with P4), a novel prototyping platform that allows to prototype heterogeneous software network scenarios, including container-based, P4-switch-based, and SmartNIC-based network functions. The presented work substantially extends our existing Containernet platform with the means to prototype offloading scenarios. Besides presenting the platform’s system design, we evaluate its scalability and show that it can run scenarios with more than 64 P4 switch or SmartNIC nodes on a single laptop. Finally, we presented a case study in which we use the presented platform to prototype an extended in-band network telemetry use case.","lang":"eng"}],"language":[{"iso":"eng"}],"ddc":["000"]},{"citation":{"mla":"Moro, Daniele, et al. “Demonstrating FOP4: A Flexible Platform to Prototype NFV Offloading Scenarios.” <i>IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN)</i>, IEEE, 2019.","bibtex":"@inproceedings{Moro_Peuster_Karl_Capone_2019, place={Dallas}, title={Demonstrating FOP4: A Flexible Platform to Prototype NFV Offloading Scenarios}, booktitle={IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN)}, publisher={IEEE}, author={Moro, Daniele and Peuster, Manuel and Karl, Holger and Capone, Antonio}, year={2019} }","short":"D.

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."}],"file":[{"creator":"ups","date_created":"2018-12-12T15:18:12Z","date_updated":"2018-12-12T15:18:12Z","file_id":"6195","access_level":"closed","file_name":"08460029.pdf","file_size":2211450,"content_type":"application/pdf","relation":"main_file","success":1},{"date_updated":"2019-01-24T10:17:00Z","date_created":"2019-01-24T10:17:00Z","creator":"sevilmeh","file_size":3445650,"file_name":"NetSoft18_RIS.pdf","file_id":"6968","access_level":"open_access","content_type":"application/pdf","relation":"main_file"}],"publication":"4th IEEE International Conference on Network Softwarization (NetSoft 2018)","ddc":["004"],"language":[{"iso":"eng"}],"year":"2018","title":"Generating Resource and Performance Models for Service Function Chains: The Video Streaming Case","publisher":"IEEE","date_created":"2018-04-24T12:11:36Z"},{"user_id":"477","department":[{"_id":"75"}],"project":[{"grant_number":"761493","name":"5G Development and validation platform for global industry-specific network services and Apps","_id":"28"},{"_id":"1","name":"SFB 901"},{"_id":"4","name":"SFB 901 - Project Area C"},{"name":"SFB 901 - Subproject C4","_id":"16"}],"_id":"2481","file_date_updated":"2018-06-25T07:40:57Z","type":"conference","status":"public","urn":"24814","author":[{"first_name":"Sevil","last_name":"Dräxler","id":"31764","full_name":"Dräxler, Sevil"},{"id":"35343","full_name":"Schneider, Stefan Balthasar","last_name":"Schneider","orcid":"0000-0001-8210-4011","first_name":"Stefan Balthasar"},{"last_name":"Karl","id":"126","full_name":"Karl, Holger","first_name":"Holger"}],"oa":"1","date_updated":"2022-01-06T06:56:38Z","conference":{"name":"4th IEEE International Conference on Network Softwarization (NetSoft 2018)","location":"Montreal"},"publication_status":"published","has_accepted_license":"1","citation":{"ama":"Dräxler S, Schneider SB, Karl H.

Current approaches are limited in flexibility and practical applicability. Specifically, we study dynamic, single-step, joint scaling and placement of network services with bidirectional flows traversing Physical or Virtual Network Functions (VNFs) and returning to their sources. 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). We show that this problem is NP-complete and also present a heuristic algorithm to find good solutions in short time. In an extensive evaluation with realistic scenarios, we investigate the capabilities of the two approaches.","lang":"eng"}],"date_created":"2018-04-24T12:14:00Z","publisher":"IEEE","title":" Scaling and Placing Bidirectional Services with Stateful Virtual and Physical Network Functions","year":"2018"},{"_id":"2483","project":[{"grant_number":"762057","name":"5G Programmable Infrastructure Converging disaggregated neTwork and compUte Resources","_id":"23"},{"_id":"1","name":"SFB 901"},{"name":"SFB 901 - Project Area C","_id":"4"},{"name":"SFB 901 - Subproject C4","_id":"16"}],"department":[{"_id":"75"}],"series_title":"KuVS-Fachgespräch Fog Computing 2018","user_id":"31764","ddc":["000"],"language":[{"iso":"eng"}],"type":"report","abstract":[{"lang":"eng","text":"Understanding the behavior of distributed cloud service components in different load situations is important for efficient and automatic management and orchestration of these services.

We want algorithms with low asymptotic competitive ratio while repacking items sparingly between updates. Formally, each item i has a movement cost c_i >= 0, and we want to use alpha * OPT bins and incur a movement cost gamma * c_i, either in the worst case, or in an amortized sense, for alpha, gamma as small as possible. We call gamma the recourse of the algorithm. This is motivated by cloud storage applications, where fully-dynamic bin packing models the problem of data backup to minimize the number of disks used, as well as communication incurred in moving file backups between disks. Since the set of files changes over time, we could recompute a solution periodically from scratch, but this would give a high number of disk rewrites, incurring a high energy cost and possible wear and tear of the disks. In this work, we present optimal tradeoffs between number of bins used and number of items repacked, as well as natural extensions of the latter measure."}],"file":[{"content_type":"application/pdf","relation":"main_file","success":1,"date_created":"2018-10-31T16:58:18Z","creator":"feldi","date_updated":"2018-10-31T16:58:18Z","file_id":"5227","file_name":"LIPIcs-ICALP-2018-51.pdf","access_level":"closed","file_size":723824}],"date_updated":"2022-01-06T06:56:39Z","volume":107,"author":[{"first_name":"Björn","full_name":"Feldkord, Björn","id":"22704","last_name":"Feldkord"},{"full_name":"Feldotto, Matthias","id":"14052","last_name":"Feldotto","orcid":"0000-0003-1348-6516","first_name":"Matthias"},{"full_name":"Gupta, Anupam","last_name":"Gupta","first_name":"Anupam"},{"last_name":"Guruganesh","full_name":"Guruganesh, Guru","first_name":"Guru"},{"first_name":"Amit ","full_name":"Kumar, Amit ","last_name":"Kumar"},{"first_name":"Sören","full_name":"Riechers, Sören","last_name":"Riechers"},{"first_name":"David","full_name":"Wajc, David","last_name":"Wajc"}],"conference":{"location":"Prag","end_date":"2018-07-13","start_date":"2018-07-10","name":"45th International Colloquium on Automata, Languages, and Programming (ICALP 2018)"},"doi":"10.4230/LIPIcs.ICALP.2018.51","has_accepted_license":"1","publication_identifier":{"issn":["1868-8969"],"isbn":["978-3-95977-076-7"]},"publication_status":"published","place":"Dagstuhl, Germany","page":"51:1-51:24","intvolume":"       107","citation":{"apa":"Feldkord, B., Feldotto, M., Gupta, A., Guruganesh, G., Kumar, A., Riechers, S., &#38; Wajc, D.

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"}],"file":[{"content_type":"application/pdf","relation":"main_file","date_updated":"2018-07-05T11:12:29Z","date_created":"2018-07-05T11:11:37Z","creator":"peuster","file_size":901561,"file_id":"3428","file_name":"main_ris.pdf","access_level":"open_access"}],"ddc":["000"],"language":[{"iso":"eng"}],"has_accepted_license":"1","publication_status":"accepted","place":"Montreal","citation":{"ama":"Peuster M, Küttner H, Karl H.

These integration tasks require testbeds that offer the\r\n  needed network function virtualization infrastructure~(NFVI), like OpenStack, introducing a\r\n  lot of management and maintenance overheads. Such testbed setups\r\n  become even more complicated when the multi\r\n  point-of-presence~(PoP) case, with multiple infrastructure\r\n  installations, is considered.\r\n\r\n  In this demo, we showcase an emulation platform that executes\r\n  containerized network services in user-defined multi-PoP\r\n  topologies. The platform does not only allow network service developers to\r\n  locally test their services but also to connect real-world\r\n  management and orchestration solutions to the emulated PoPs. During our\r\n  interactive demonstration we focus on the integration between\r\n  the emulated infrastructure and state-of-the-art orchestration\r\n  solutions like SONATA or OSM."}],"language":[{"iso":"eng"}],"ddc":["000"]}]
