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."}],"publication":"4th IEEE International Conference on Network Softwarization (NetSoft 2018)","type":"conference","department":[{"_id":"75"}],"file":[{"creator":"sevilmeh","date_created":"2018-06-25T07:40:57Z","file_name":"RIS.pdf","file_size":1471937,"access_level":"open_access","relation":"main_file","date_updated":"2018-06-25T07:40:57Z","file_id":"3319","content_type":"application/pdf"}],"date_created":"2018-04-24T12:14:00Z"},{"type":"conference","oa":"1","file":[{"content_type":"application/pdf","file_id":"6969","file_size":215571,"access_level":"open_access","file_name":"eucnc18_RIS.pdf","date_updated":"2019-01-24T10:29:12Z","relation":"main_file","date_created":"2019-01-24T10:29:12Z","creator":"sevilmeh"}],"date_created":"2018-04-24T12:17:15Z","project":[{"grant_number":"762057","_id":"23","name":"5G Programmable Infrastructure Converging disaggregated neTwork and compUte Resources"}],"publication":"27th European Conference on Networks and Communications (EUCNC 2018)","file_date_updated":"2019-01-24T10:29:12Z","citation":{"ama":"Dräxler S, Karl H, Razzaghi Kouchaksaraei H, et al. 5G OS: Control and Orchestration of Services on Multi-Domain Heterogeneous 5G Infrastructures.

While general management requirements such as Virtual Network Function (VNF) resource requirements can be specified by the service developers using service descriptors, specific management operations like VNF-specific configuration cannot be performed by these descriptors. On the other hand, it is inefficient and also very challenging for Management and Orchestration (MANO) frameworks to provide all specific-management operations for every individual network service and their constituent VNFs. To mitigate this issue, we propose the use of service-specific programs called Specific Managers (SMs) that can customize management and orchestration of network services and also extend the capability of MANO frameworks to support per-service management and orchestration. The results of our evaluation show that the higher flexibility and programmability enabled by SMs improve the performance of the service performance and also utilises the service provider resources more efficiently."}],"publication":"2018 European Conference on Networks and Communications (EuCNC)","department":[{"_id":"34"}],"type":"conference","date_created":"2018-05-07T12:30:54Z","file":[{"file_id":"3357","content_type":"application/pdf","relation":"main_file","date_updated":"2018-06-25T13:58:12Z","file_name":"specific_management.pdf","file_size":183859,"access_level":"open_access","date_created":"2018-06-25T13:52:03Z","creator":"hadik3r"}],"publication_status":"accepted","date_updated":"2022-01-06T06:57:25Z","author":[{"full_name":"Razzaghi Kouchaksaraei, Hadi","last_name":"Razzaghi Kouchaksaraei","first_name":"Hadi","id":"60845"},{"id":"31764","full_name":"Dräxler, Sevil","last_name":"Dräxler","first_name":"Sevil"},{"last_name":"Peuster","first_name":"Manuel","full_name":"Peuster, Manuel","id":"13271"},{"first_name":"Holger","last_name":"Karl","full_name":"Karl, Holger","id":"126"}],"title":"Programmable and Flexible Management and Orchestration of Virtualized Network Functions","year":"2018","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1"}]},{"main_file_link":[{"open_access":"1"}],"publication_status":"accepted","date_updated":"2022-01-06T06:57:25Z","year":"2018","title":"Pishahang: Joint Orchestration of Network Function Chains and Distributed Cloud Applications","author":[{"id":"60845","full_name":"Razzaghi Kouchaksaraei, Hadi","last_name":"Razzaghi Kouchaksaraei","first_name":"Hadi"},{"full_name":"Dierich, Tobias","first_name":"Tobias","last_name":"Dierich"},{"id":"126","last_name":"Karl","first_name":"Holger","full_name":"Karl, Holger"}],"type":"conference","department":[{"_id":"34"}],"file":[{"date_created":"2018-06-25T13:56:37Z","creator":"hadik3r","content_type":"application/pdf","file_id":"3358","date_updated":"2018-06-25T13:56:37Z","relation":"main_file","access_level":"open_access","file_size":1113319,"file_name":"submitted.pdf"}],"date_created":"2018-05-07T12:36:27Z","abstract":[{"text":"Developing cloud applications using a microservice architecture allows their functional blocks to be distributed and\r\ndeployed on multiple Cloud infrastructures.

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."}],"publication":"4th IEEE International Conference on Network Softwarization (NetSoft 2018)","type":"conference","department":[{"_id":"75"}],"file":[{"creator":"peuster","date_created":"2018-07-05T11:11:37Z","access_level":"open_access","file_size":901561,"file_name":"main_ris.pdf","date_updated":"2018-07-05T11:12:29Z","relation":"main_file","content_type":"application/pdf","file_id":"3428"}],"date_created":"2018-06-25T12:21:49Z","publication_status":"accepted","date_updated":"2022-01-06T06:59:11Z","title":" Let the state follow its flows: An SDN-based flow handover protocol to support state migration","year":"2018","author":[{"id":"13271","first_name":"Manuel","last_name":"Peuster","full_name":"Peuster, Manuel"},{"last_name":"Küttner","first_name":"Hannes","full_name":"Küttner, Hannes"},{"id":"126","full_name":"Karl, Holger","first_name":"Holger","last_name":"Karl"}],"doi":"10.1109/NETSOFT.2018.8460007","main_file_link":[{"url":"https://ieeexplore.ieee.org/document/8460007/"}],"language":[{"iso":"eng"}],"project":[{"_id":"28","grant_number":"761493","name":"5G Development and validation platform for global industry-specific network services and Apps"},{"_id":"1","name":"SFB 901"},{"name":"SFB 901 - Project Area C","_id":"4"},{"_id":"16","name":"SFB 901 - Subproject C4"}],"file_date_updated":"2018-07-05T11:12:29Z","citation":{"chicago":"Peuster, Manuel, Hannes Küttner, and Holger Karl. “ Let the State Follow Its Flows: An SDN-Based Flow Handover Protocol to Support State Migration.” In <i>4th IEEE International Conference on Network Softwarization (NetSoft 2018)</i>.

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. Further, we present a case study in which we test ETSI's Open Source MANO~(OSM) against our proposed system  to gain insights about OSM's behaviour in large-scale NFV deployments."}],"publication":"European Conference on Networks and Communications (EuCNC)","department":[{"_id":"75"}],"type":"conference","date_created":"2018-06-25T12:27:59Z","file":[{"file_size":713495,"access_level":"open_access","file_name":"main_ris.pdf","date_updated":"2018-07-05T11:13:29Z","relation":"main_file","content_type":"application/pdf","file_id":"3430","creator":"peuster","date_created":"2018-07-05T11:13:29Z"}],"publication_status":"accepted","date_updated":"2022-01-06T06:59:12Z","author":[{"id":"13271","full_name":"Peuster, Manuel","first_name":"Manuel","last_name":"Peuster"},{"full_name":"Marchetti, Michael","last_name":"Marchetti","first_name":"Michael"},{"first_name":"Gerado","last_name":"Garcia de Blas","full_name":"Garcia de Blas, Gerado"},{"id":"126","full_name":"Karl, Holger","last_name":"Karl","first_name":"Holger"}],"year":"2018","title":"Emulation-based Smoke Testing of NFV Orchestrators in Large Multi-PoP Environments","doi":"10.1109/EuCNC.2018.8442701","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://ieeexplore.ieee.org/document/8442701/"}]},{"has_accepted_license":"1","conference":{"end_date":"2018-09-14","name":"European Conference on Machine Learning and Principles and Practice of Knowledge Discovery in Databases","start_date":"2018-09-10","location":"Dublin, Ireland"},"status":"public","user_id":"5786","ddc":["000"],"publisher":"Springer","_id":"3510","page":"1495-1515","project":[{"_id":"1","name":"SFB 901"},{"_id":"3","name":"SFB 901 - Project Area B"},{"name":"SFB 901 - Subproject B2","_id":"10"},{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"citation":{"mla":"Mohr, Felix, et al. “ML-Plan: Automated Machine Learning via Hierarchical Planning.” <i>Machine Learning</i>, Springer, 2018, pp. 1495–515, doi:<a href=\"https://doi.org/10.1007/s10994-018-5735-z\">10.1007/s10994-018-5735-z</a>.","apa":"Mohr, F., Wever, M.

A critical angle can be defined beyond which all radiation losses are suppressed. Additionally an increase of the curvature radius of the bends also leads to low-loss configurations for incidence angles below that critical angle. A combination of two bent corner systems represents a step-like structure, behaving like a Fabry-Perot interferometer, with two partial reflectors separated by the vertical height between the horizontal slabs. We numerically analyse typical high-index-contrast Si/SiO2 structures for their reflectance and transmittance properties. When increasing the curvature radius the resonant effect becomes less relevant such that full transmittance is reached with less critical conditions on the vertical distance or the incidence angle. For practical interest 3-D problems are considered, where the structures are excited by the fundamental mode of a wide, shallow rib waveguide. High transmittance levels can be observed also for these 3-D configurations depending on the width of the rib."}],"issue":"14","publication":"Optics Express","volume":26,"ddc":["620"],"user_id":"158","publisher":"OSA Publishing","_id":"3740","urn":"37409","page":"18621-18632","has_accepted_license":"1","status":"public","oa":"1","project":[{"_id":"56","name":"TRR 142 - Project Area C"},{"name":"TRR 142","_id":"53"},{"_id":"75","name":"TRR 142 - Subproject C5"}],"citation":{"ieee":"L.

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."}],"file":[{"creator":"ups","date_created":"2018-11-02T15:25:49Z","relation":"main_file","date_updated":"2018-11-02T15:25:49Z","file_name":"08382313.pdf","file_size":1767054,"access_level":"closed","file_id":"5302","content_type":"application/pdf","success":1},{"relation":"main_file","date_updated":"2019-01-21T16:12:36Z","file_name":"TNSM2846572_RIS.pdf","access_level":"open_access","file_size":2878350,"file_id":"6950","content_type":"application/pdf","creator":"sevilmeh","date_created":"2019-01-21T16:12:36Z"}],"date_created":"2018-06-11T06:55:05Z","type":"journal_article","department":[{"_id":"75"}]},{"has_accepted_license":"1","conference":{"end_date":"2018-07-19","location":"Kyoto, Japan","name":"GECCO 2018","start_date":"2018-07-15"},"status":"public","user_id":"33176","ddc":["000"],"publisher":"ACM","_id":"2109","project":[{"_id":"1","name":"SFB 901"},{"_id":"3","name":"SFB 901 - Project Area B"},{"name":"SFB 901 - Subproject B2","_id":"10"},{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"citation":{"short":"M.D. Wever, F.

For example, by recursively bisecting the original set of classes, so-called nested dichotomies define a set of binary classification problems that are organized in the structure of a binary tree. In contrast to the existing one-shot heuristics for constructing nested dichotomies and motivated by recent work on algorithm configuration, we propose a genetic algorithm for optimizing the structure of such dichotomies. A key component of this approach is the proposed genetic representation that facilitates the application of standard genetic operators, while still supporting the exchange of partial solutions under recombination. We evaluate the approach in an extensive experimental study, showing that it yields classifiers with superior generalization performance.","lang":"eng"}],"publication":"Proceedings of the Genetic and Evolutionary Computation Conference, GECCO 2018, Kyoto, Japan, July 15-19, 2018","department":[{"_id":"355"}],"keyword":["Classification","Hierarchical Decomposition","Indirect Encoding"],"type":"conference","date_created":"2018-03-31T13:51:23Z","file":[{"creator":"ups","date_created":"2018-11-02T14:33:54Z","file_size":875404,"access_level":"closed","file_name":"p561-wever.pdf","date_updated":"2018-11-02T14:33:54Z","relation":"main_file","content_type":"application/pdf","success":1,"file_id":"5275"}]}]
