As it is not economic to interconnect all machines in the data center using a full-bisection-bandwidth network, techniques have to be developed to increase the efficiency of data-center networks. The Software-Defined Network paradigm opened the door for centralized traffic engineering (TE) in such environments. Up to now, there were already a number of TE proposals for SDN-controlled data centers that all work very well. However, these techniques either use a high amount of flow table entries or a high flow installation rate that overwhelms available switching hardware, or they require custom or very expensive end-of-line equipment to be usable in practice. We present HybridTE, a TE technique that uses (uncertain) information about large flows. Using this extra information, our technique has very low hardware requirements while maintaining better performance than existing TE techniques. This enables us to build very low-cost, high performance data-center networks.","lang":"eng"}],"urn":"2875","user_id":"15572","department":[{"_id":"75"}],"project":[{"_id":"1","name":"SFB 901"},{"name":"SFB 901 - Subprojekt A2","_id":"6"},{"_id":"2","name":"SFB 901 - Project Area A"}],"_id":"287","file_date_updated":"2018-03-08T09:59:05Z","ddc":["040"]},{"type":"conference","publication":"Proceedings of the 4th European Workshop on Software Defined Networks (EWSDN 2015)","abstract":[{"text":"Multi-rooted trees are becoming the norm for modern data-center networks. In these networks, scalable flow routing is challenging owing to vast number of flows. Current approaches either employ a central controller that can have scalability issues or a scalable decentralized algorithm only considering local information. In this paper we present a new decentralized approach to least-congested path routing in software-defined data center networks that has neither of these issues: By duplicating the initial (or SYN) packet of a flow and estimating the data rate of multiple flows in parallel, we exploit TCP’s habit to fill buffers to find the least congested path. We show that our algorithm significantly improves flow completion time without the need for a central controller or specialized hardware.","lang":"eng"}],"file":[{"file_size":277574,"file_name":"247-07313613.pdf","file_id":"1491","access_level":"closed","date_updated":"2018-03-21T09:46:21Z","date_created":"2018-03-21T09:46:21Z","creator":"florida","success":1,"relation":"main_file","content_type":"application/pdf"}],"status":"public","project":[{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Subprojekt A2","_id":"6"},{"name":"SFB 901 - Project Area A","_id":"2"}],"_id":"247","user_id":"15504","department":[{"_id":"75"}],"ddc":["040"],"file_date_updated":"2018-03-21T09:46:21Z","has_accepted_license":"1","year":"2015","citation":{"ieee":"A.

One recent solution for this is based on a two-layered network that uses long-range macro cells to provide a full coverage signaling overlay and short-range small cells for fast data transmissions. These small cells can be switched off when they are not needed and allow network-wide energy optimizations.\r\n\r\nThis paper presents an architecture that extends existing mobile networks to integrate a small cell layer that supports on-demand cell activation. We discuss how additional small cells can be interconnected with existing core components and how they can be controlled by a resource management component. \r\nFinally, a Wi-Fi based proof of concept testbed implementation is presented that demonstrates the feasibility of the approach."}],"file":[{"content_type":"application/pdf","creator":"ups","file_size":1916017,"file_name":"p25-peuster.pdf","success":1,"relation":"main_file","date_updated":"2018-11-02T14:06:06Z","open_access":1,"date_created":"2018-11-02T14:06:06Z","access_level":"closed","file_id":"5261"}],"publication":"Proceedings of the 5th Workshop on All Things Cellular: Operations, Applications and Challenges","title":"An Architecture for Energy-aware On-demand Mobile Network Management","date_created":"2017-11-27T10:22:29Z","year":"2015"},{"user_id":"15572","department":[{"_id":"75"}],"project":[{"grant_number":"318115","name":"Connectivity management for eneRgy Optimised Wireless Dense works","_id":"22","call_identifier":"FP7-ICT-2011-C"}],"_id":"1636","type":"conference","publication":"2015 European Conference on Networks and Communications (EuCNC)","status":"public","date_created":"2018-03-22T13:33:59Z","author":[{"first_name":"Sébastien","last_name":"Auroux","full_name":"Auroux, Sébastien","id":"42575"},{"last_name":"Draxler","full_name":"Draxler, Martin","first_name":"Martin"},{"first_name":"Arianna","full_name":"Morelli, Arianna","last_name":"Morelli"},{"first_name":"Vincenzo","full_name":"Mancuso, Vincenzo","last_name":"Mancuso"}],"date_updated":"2022-01-06T06:52:49Z","publisher":"IEEE","doi":"10.1109/eucnc.2015.7194057","title":"Dynamic network reconfiguration in wireless DenseNets with the CROWD SDN architecture","publication_status":"published","publication_identifier":{"isbn":["9781467373593"]},"ec_funded":"1","citation":{"bibtex":"@inproceedings{Auroux_Draxler_Morelli_Mancuso_2015, title={Dynamic network reconfiguration in wireless DenseNets with the CROWD SDN architecture}, DOI={<a href=\"https://doi.org/10.1109/eucnc.2015.7194057\">10.1109/eucnc.2015.7194057</a>}, booktitle={2015 European Conference on Networks and Communications (EuCNC)}, publisher={IEEE}, author={Auroux, Sébastien and Draxler, Martin and Morelli, Arianna and Mancuso, Vincenzo}, year={2015} }","short":"S.

Up to now, there is no emulation tool that is able to emulate large software-defined data center networks that consist of several thousand nodes. Mininet is the most common tool to emulate Software-Defined Networks of several hundred nodes. We extend Mininet to span an emulated network over several physical machines, making it possible to emulate networks of several thousand nodes on just a handful of physical machines. This enables us to emulate, e.g., large data center networks. To test this approach, we additionally introduce a traffic generator for data center traffic. Since there are no data center traffic traces publicly available we use the results of two recent traffic studies to create synthetic traffic. We show the design and discuss some challenges we had in building our traffic generator. As a showcase for our work we emulated a data center consisting of 3200 hosts on a cluster of only 12 physical machines. We show the resulting workloads and the trade-offs involved."}],"file":[{"date_updated":"2018-03-20T07:30:29Z","date_created":"2018-03-20T07:30:29Z","creator":"florida","file_size":786320,"file_name":"329-maxinet_networking14_01.pdf","file_id":"1425","access_level":"closed","content_type":"application/pdf","success":1,"relation":"main_file"}],"status":"public","type":"conference","publication":"Proceedings of the 2014 IFIP Networking Conference (Networking 2014)"},{"title":"Using Application Layer Knowledge in Routing and Wavelength Assignment Algorithms","doi":"10.1109/ICC.2014.6883825","date_updated":"2022-01-06T06:59:14Z","date_created":"2017-10-17T12:41:58Z","author":[{"first_name":"Philip","full_name":"Wette, Philip","last_name":"Wette"},{"first_name":"Holger","full_name":"Karl, Holger","id":"126","last_name":"Karl"}],"year":"2014","citation":{"ama":"Wette P, Karl H.

Thus, if dedicated properties of the networktopology are required by the applications running on the network,these requirements have to be known to the RWA algorithm.We present a family of preemptive RWA algorithms for WDMnetworks. These algorithms have two distinguishing features: a)they can handle dynamic traffic by on-the-fly reconfiguration,and b) users can give feedback for reconfiguration decisions andthus influence the preemption decision of the RWA algorithm,leading to networks which adapt directly to application needs.This is different from traffic engineering where the network is(slowly) adapted to observed traffic patterns.Our algorithms handle various WDM network configurationsincluding networks consisting of heterogeneous WDM hardware.To this end, we are using the layered graph approach togetherwith a newly developed graph model that is used to determineconflicting lightpaths.","lang":"eng"}],"file":[{"success":1,"relation":"main_file","content_type":"application/pdf","file_size":138062,"file_name":"339-IEEE-WK-14.pdf","access_level":"closed","file_id":"1422","date_updated":"2018-03-20T07:29:00Z","creator":"florida","date_created":"2018-03-20T07:29:00Z"}],"status":"public","type":"conference","publication":"Proceedings of the IEEE International Conference on Communications 2014"},{"file":[{"creator":"florida","date_created":"2018-03-20T07:28:26Z","date_updated":"2018-03-20T07:28:26Z","access_level":"closed","file_id":"1421","file_name":"343-2014_Diss_Kuensemoeller.pdf","file_size":1378657,"content_type":"application/pdf","relation":"main_file","success":1}],"status":"public","type":"dissertation","ddc":["040"],"file_date_updated":"2018-03-20T07:28:26Z","project":[{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Subprojekt A2","_id":"6"},{"name":"SFB 901 - Subprojekt A3","_id":"7"},{"name":"SFB 901 - Project Area A","_id":"2"}],"_id":"343","user_id":"477","department":[{"_id":"75"}],"year":"2014","citation":{"ieee":"J.

Recent research developed algorithms to find optimal locations for virtual machines. However, those algorithms assume to have either single-tier applications or a fixed number of virtual machines – a strong simplification of reality. This paper investigates the placement and scaling of complex application architectures. An application is dynamically scaled to fit both the current demand situation and the currently available infrastructure resources. We compare two approaches: The first one is based on virtual network embedding. The second approach is a novel method called Template Embedding. It is based on a hierarchical 1-allocation hub flow problem and combines applica- tion scaling and embedding in one step. Extensive experiments on 43200 network configurations showed that Template Embedding outperforms virtual network embedding in all cases in three metrics: success rate, solution quality, and runtime. This positive result shows that template embedding is a promising approach for distributed cloud resource allocation.","lang":"eng"}],"status":"public","file":[{"relation":"main_file","success":1,"content_type":"application/pdf","access_level":"closed","file_name":"354-keller_ucc14_preprint_01.pdf","file_id":"1413","file_size":737652,"date_created":"2018-03-20T07:23:02Z","creator":"florida","date_updated":"2018-03-20T07:23:02Z"}],"publication":"Proceedings of 7th International Conference on Utility and Cloud Computing (UCC)","type":"conference","ddc":["040"],"file_date_updated":"2018-03-20T07:23:02Z","_id":"354","project":[{"name":"SFB 901","_id":"1"},{"_id":"6","name":"SFB 901 - Subprojekt A2"},{"_id":"2","name":"SFB 901 - Project Area A"}],"department":[{"_id":"75"}],"user_id":"15572"},{"doi":"10.1109/CloudNet.2014.6968961","title":"Specifying and Placing Chains of Virtual Network Functions","date_created":"2017-10-17T12:42:02Z","author":[{"last_name":"Dräxler","id":"31764","full_name":"Dräxler, Sevil","first_name":"Sevil"},{"full_name":"Keller, Matthias","last_name":"Keller","first_name":"Matthias"},{"first_name":"Holger","last_name":"Karl","full_name":"Karl, Holger","id":"126"}],"oa":"1","date_updated":"2022-01-06T06:59:27Z","citation":{"mla":"Dräxler, Sevil, et al. “Specifying and Placing Chains of Virtual Network Functions.” <i>Proceedings of the 3rd International Conference on Cloud Networking (CloudNet)</i>, 2014, pp. 7–13, doi:<a href=\"https://doi.org/10.1109/CloudNet.2014.6968961\">10.1109/CloudNet.2014.6968961</a>.","bibtex":"@inproceedings{Dräxler_Keller_Karl_2014, title={Specifying and Placing Chains of Virtual Network Functions}, DOI={<a href=\"https://doi.org/10.1109/CloudNet.2014.6968961\">10.1109/CloudNet.2014.6968961</a>}, booktitle={Proceedings of the 3rd International Conference on Cloud Networking (CloudNet)}, author={Dräxler, Sevil and Keller, Matthias and Karl, Holger}, year={2014}, pages={7–13} }","short":"S.
