These microservices are clearly bounded for each other and expose their functionality through, for instance, RESTful application inter- faces. Particularly the clear boundaries between microservices enable the reuse of microservice throughout different projects. Because of the increasing use of microservices, the composition of multiple microservices in service composition becomes a more important task. A challenging area in developing service compo- sitions is that it involves two distinct layers with few junctions. On the one hand, describes a service composition a business process, which involves multiple com- ponents. On the other hand, involves the implementation of a service composition topics like service discovery and message exchange protocols since the microser- vices involved in a service composition are located within a network environment. In this Bachelor’s Thesis, I describe a descriptions language to abstractly describe the business logic of a service composition. Furthermore, I describe a genera- tion process, which compiles this abstract description to a working microservice realizing the specified service composition. In addition to that, I provide an im- plementation of the generation process, as a proof of concept, and test it within a Kubernetes-based cluster environment.","lang":"eng"}],"project":[{"_id":"16","name":"SFB 901 - Subproject C4"},{"_id":"1","name":"SFB 901"},{"_id":"4","name":"SFB 901 - Project Area C"}],"supervisor":[{"first_name":"Holger","last_name":"Karl","full_name":"Karl, Holger","id":"126"}],"citation":{"mla":"Schürmann, Andreas. <i>Microservice-Based Execution Environment for Service Compositions</i>.

For extended flexibility, we go beyond seeing services as a fixed chain of functions. We define the service structure in a flexible way that enables changing the order of functions in case the functionality of the service is not influenced by this, and propose a YANG data model for expressing this flexibility. Flexible structures allow the network orchestration system to choose the optimal composition of service components that for example gives the best results for placement of services in the network. When number of flexible services and number of components in each service increase, combinatorial explosion limits the practical use of this flexibility. In this paper, we describe a selection heuristic that gives a Pareto set of the possible compositions of a service as well as possible combinations of different services, with respect to different optimization objectives. Moreover, we present a heuristic algorithm for placement of a combination of services, which aims at placing service components along shortest paths that have enough capacity for accommodating the services. By applying these solutions, we show that allowing flexibility in the service structure is feasible.","lang":"eng"}],"file":[{"file_id":"1579","content_type":"application/pdf","file_name":"58-preprint-ijnm.pdf","access_level":"open_access","file_size":2765738,"relation":"hidden","date_updated":"2018-06-13T09:15:42Z","date_created":"2018-03-21T13:18:13Z","creator":"florida"},{"date_created":"2018-06-13T09:22:37Z","creator":"sevilmeh","file_id":"3197","content_type":"application/pdf","file_name":"58-accepted-ijnm.pdf","access_level":"open_access","file_size":2766920,"relation":"main_file","date_updated":"2018-06-13T09:22:37Z"}],"date_created":"2017-10-17T12:41:02Z","type":"journal_article","department":[{"_id":"75"}],"status":"public","has_accepted_license":"1","page":"1--16","_id":"58","urn":"582","publisher":"Wiley Online Library","ddc":["040"],"user_id":"477","file_date_updated":"2018-06-13T09:22:37Z","citation":{"short":"S.

This paves the way for wide-area service deployments with improved service quality: e.g. user-perceived response times can be reduced by offering services at nearby sites. But always assigning users to the nearest site can be a bad decision if this site is already highly utilised. This paper formalises two related decisions of allocating compute resources at different sites and assigning users to them with the goal of minimising the response times while the total number of resources to be allocated is limited – a non-linear capacitated Facility Location Problem with integrated queuing systems. To efficiently handle its non-linearity, we introduce five linear problem linearisations and adapt the currently best heuristic for a similar scenario to our scenario. All six approaches are compared in experiments for solution quality and solving time. Surprisingly, our best optimisation formulation outperforms the heuristic in both time and quality. Additionally, we evaluate the influence of distributions of available compute resources in the network on the response time: The time was halved for some configurations. The presented formulation techniques for our problem linearisations are applicable to a broader optimisation domain."}],"date_created":"2017-10-17T12:41:03Z","file":[{"date_created":"2018-03-21T13:15:53Z","creator":"florida","file_id":"1576","success":1,"content_type":"application/pdf","relation":"main_file","date_updated":"2018-03-21T13:15:53Z","file_name":"64-07572217.pdf","access_level":"closed","file_size":1505773}],"department":[{"_id":"75"}],"type":"journal_article","author":[{"first_name":"Matthias","last_name":"Keller","full_name":"Keller, Matthias"},{"id":"126","last_name":"Karl","first_name":"Holger","full_name":"Karl, Holger"}],"title":"Response-Time-Optimised Service Deployment: MILP Formulations of Piece-wise Linear Functions Approximating Non-linear Bivariate Mixed-integer Functions","year":"2017","date_updated":"2022-01-06T07:03:03Z","doi":"10.1109/TNSM.2016.2611590"},{"conference":{"location":"Bologna"},"author":[{"last_name":"Schwabe","first_name":"Arne","full_name":"Schwabe, Arne"},{"last_name":"Rojas","first_name":"Elisa","full_name":"Rojas, Elisa"},{"id":"126","first_name":"Holger","last_name":"Karl","full_name":"Karl, Holger"}],"year":"2017","title":"Minimizing downtimes: Using dynamic reconfiguration and state management in SDN","status":"public","date_updated":"2022-01-06T07:03:27Z","_id":"708","page":"1--5","doi":"10.1109/NETSOFT.2017.8004209","user_id":"15572","citation":{"short":"A.

Network softwarization and network function virtualization have been introduced to tackle these problems, aiming at decreasing costs and complexity of implementing new services, maintaining the implemented services, and managing available resources in service provisioning platforms and underlying infrastructures. To experience the full potential of these approaches, innovative development support tools and service provisioning environments are needed. To answer these needs, we introduce the architecture of the open-source SONATA system, a service programming, orchestration, and management framework. We present a development toolchain for virtualized network services, fully integrated with a service platform and orchestration system. We introduce the modular and flexible architecture of our system and discuss its main components and features, such as function- and service-specific managers that allow fine-grained service management, slicing support to facilitate multi-tenancy, recursiveness for improved scalability, and full-featured DevOps support.","lang":"eng"}],"file":[{"date_created":"2018-11-02T14:22:10Z","creator":"ups","success":1,"content_type":"application/pdf","file_id":"5270","access_level":"closed","file_size":821211,"file_name":"07962785.pdf","date_updated":"2018-11-02T14:22:10Z","relation":"main_file"}],"date_created":"2017-11-22T09:42:59Z","type":"conference","department":[{"_id":"75"}],"status":"public","conference":{"end_date":"2017-05-25","location":"Paris, France","start_date":"2017-05-21","name":"2017 IEEE International Conference on Communications Workshops (ICC Workshops)"},"has_accepted_license":"1","publisher":"IEEE","_id":"717","ddc":["000"],"user_id":"31764","file_date_updated":"2018-11-02T14:22:10Z","citation":{"mla":"Dräxler, Sevil, et al. “SONATA: Service Programming and Orchestration for Virtualized Software Networks.” <i>2017 IEEE International Conference on Communications Workshops (ICC Workshops)</i>, IEEE, 2017, doi:<a href=\"https://doi.org/10.1109/iccw.2017.7962785\">10.1109/iccw.2017.7962785</a>.","bibtex":"@inproceedings{Dräxler_Karl_Peuster_Razzaghi Kouchaksaraei_Bredel_Lessmann_Soenen_Tavernier_Mendel-Brin_Xilouris_2017, title={SONATA: Service programming and orchestration for virtualized software networks}, DOI={<a href=\"https://doi.org/10.1109/iccw.2017.7962785\">10.1109/iccw.2017.7962785</a>}, booktitle={2017 IEEE International Conference on Communications Workshops (ICC Workshops)}, publisher={IEEE}, author={Dräxler, Sevil and Karl, Holger and Peuster, Manuel and Razzaghi Kouchaksaraei, Hadi and Bredel, Michael and Lessmann, Johannes and Soenen, Thomas and Tavernier, Wouter and Mendel-Brin, Sharon and Xilouris, George}, year={2017} }","ama":"Dräxler S, Karl H, Peuster M, et al.

This becomes even more challenging when agile development methodologies, like DevOps, are applied. In such scenarios, management and orchestration systems are continuously facing new versions of functions and services which makes it hard to decide how much resources have to be allocated to them to provide the expected service performance. \r\nOne solution for this problem is to support resource allocation decisions with performance behavior information obtained by profiling techniques applied to such network functions and services.\r\n\r\nIn this position paper, we analyze and discuss the components needed to generate such performance behavior information within the NFV DevOps workflow. We also outline research questions that identify open issues and missing pieces for a fully integrated NFV profiling solution. Further, we introduce a novel profiling mechanism that is able to profile virtualized network functions and entire network service chains under different resource constraints before they are deployed on production infrastructure."}],"language":[{"iso":"eng"}],"main_file_link":[{"url":"http://ieeexplore.ieee.org/document/7956044/"}],"doi":"10.1109/EWSDN.2016.9","author":[{"full_name":"Peuster, Manuel","first_name":"Manuel","last_name":"Peuster","id":"13271"},{"first_name":"Holger","last_name":"Karl","full_name":"Karl, Holger","id":"126"}],"year":"2016","title":"Understand Your Chains: Towards Performance Profile-Based Network Service Management","publication_status":"published","date_updated":"2022-01-06T07:03:33Z","oa":"1","citation":{"mla":"Peuster, Manuel, and Holger Karl. “Understand Your Chains: Towards Performance Profile-Based Network Service Management.” <i>Fifth European Workshop on Software-Defined Networks, EWSDN 2016, Den Haag, The Netherlands, October 10-11, 2016</i>, 2016, pp. 7--12, doi:<a href=\"https://doi.org/10.1109/EWSDN.2016.9\">10.1109/EWSDN.2016.9</a>.","bibtex":"@inproceedings{Peuster_Karl_2016, title={Understand Your Chains: Towards Performance Profile-Based Network Service Management}, DOI={<a href=\"https://doi.org/10.1109/EWSDN.2016.9\">10.1109/EWSDN.2016.9</a>}, booktitle={Fifth European Workshop on Software-Defined Networks, EWSDN 2016, Den Haag, The Netherlands, October 10-11, 2016}, author={Peuster, Manuel and Karl, Holger}, year={2016}, pages={7--12} }","ama":"Peuster M, Karl H.

Two-layer mobile networks with separated signalling and data layers have been recently proposed for energy savings in future implementations. These networks are able to switch off unneeded data cells completely while maintaining full coverage with their signalling cells, thus saving energy. In this demonstration, we showcase a testbed that uses Wi-Fi access points to emulate small cells of the data layer and a publicly available cellular connection as the signalling layer. We use off-the-shelf Android smartphones with an ad-hoc networking management module and a MultiPath TCP-enabled kernel to manage the Wi-Fi and cellular interfaces simultaneously.\r\nThe testbed is used to demonstrate the general feasibility of this layered architecture and to facilitate experiments with network-wide resource optimization.
