However, packet-level information is crucial for the timely and reliable detection, investigation, and mitigation of security incidents. Currently, no solution effectively balances these two contradicting approaches, forcing network operators to compromise between efficiency and accuracy. In this paper, we thus propose HybridMon, a hybrid solution that combines condensed packet-level monitoring with selective flow-based aggregation to strike a new balance between efficiency and accuracy. Operating on the data plane of P4-programmable switches, HybridMon enables fine-grained, practical, and flexible network monitoring at Tbps speeds. We validate the effectiveness of HybridMon through extensive evaluations using Internet backbone and university campus traffic traces, demonstrating its reliability and performance in network forensics and intrusion detection contexts. Our results show that HybridMon reliably monitors all flows while reducing the output bandwidth to 12 % to 20 % compared to packet monitoring when exporting standard features.

Thus, deploying redundant hardware for both local and wide area communication, along with protocols that leverage these redundancies for automatic and timely failovers, is fundamental. This paper presents a comprehensive overview of key protocols (PRP/HSR, MPLS-TP, and MPTCP) which offer robust recovery mechanisms. Additionally, it provides a specific concept and topology that effectively combine the presented protocols to ensure resilient communication from the control center to substation devices. ven2us https://digital-library.theiet.org/doi/pdf/10.1049/icp.2024.2609 Proceedings of the CIRED Chicago Workshop 2024 on Resilience of Electric Distribution Systems, November 7-8, 2024, Chicago, USA Chicago CIRED Chicago Workshop 2024 on Resilience of Electric Distribution Systems November 7-8, 2024 10.1049/icp.2024.2609 1 Ina BereniceFink MarkusDahlmanns GerritErichsen KlausWehrle inproceedings 2024-buildsys-breyer-transferstudy 2024 11 6 333-336 www.comsys.rwth-aachen.de/fileadmin/papers/2024/2024-breyer-transferstudy.pdf Online ACM Proceedings of the 11th ACM International Conference on Systems for Energy-Efficient Buildings, Cities, and Transportation (BuildSys 2024), Hangzhou, China en 979-8-4007-0706-3/24/11 10.1145/3671127.3699532 1 JustusBreyer SparshJauhari RenéGlebke Muhammad HamadAlizai MarkusStroot KlausWehrle inproceedings 2024-buildsys-breyer-waterreview 2024 11 6 318-322 www.comsys.rwth-aachen.de/fileadmin/papers/2024/2024-breyer-waterreview.pdf Online ACM Proceedings of the 11th ACM International Conference on Systems for Energy-Efficient Buildings, Cities, and Transportation (BuildSys 2024), Hangzhou, China en 979-8-4007-0706-3/24/11 10.1145/3671127.3698793 1 JustusBreyer MaximilianPetri Muhammad HamadAlizai KlausWehrle inproceedings 2024-wagner-madtls 2024 7 1 https://www.comsys.rwth-aachen.de/fileadmin/papers/2024/2024-wagner-madtls.pdf ACM 19th ACM ASIA Conference on Computer and Communications Security (ACM AsiaCCS '24), Singapur Singapur ACM ASIA Conference on Computer and Communications Security (AsiaCCS) July 1-5, 2024 10.1145/3634737.3637640 1 EricWagner DavidHeye MartinSerror IkeKunze KlausWehrle MartinHenze inproceedings 2024-dahlmanns-cired 2024 6 19 The increasing demands on the power grid require intelligent and flexible solutions that ensure the grid's stability. Many of these measures involve sophisticated communication between the control center and the stations that is not efficiently realizable using traditional protocols, e.g., IEC 60870-5-104. To this end, IEC 61850 introduces data models which allow flexible communication. Still, the specification leaves open how DSOs should interconnect their stations to realize resilient communication between the control center and station devices. However, DSOs require such communication to adapt modern solutions increasing the grid's capacity, e.g., adaptive protection systems. In this paper, we present our envisioned network and communication concept for future DSO's ICT infrastructures that enables the control center to resiliently and flexibly communicate with station devices. For resilience, we suggest interconnecting each station with two distinct communication paths to the control center, use MPLS-TP and MPTCP for fast failovers when a single link fails, and mTLS to protect the communication possibilities against misuse. Additionally, in accordance with IEC 61850, we envision the control center to communicate with the station devices using MMS by using the station RTU as a proxy. ven2us Proceedings of the CIRED workshop on Increasing Distribution Network Hosting Capacity 2024, June 19-20, 2024, Vienna, Austria Vienna CIRED workshop on Increasing Distribution Network Hosting Capacity 2024 June 19-20, 2024 10.1049/icp.2024.2096 1 MarkusDahlmanns Ina BereniceFink GerritErichsen GuosongLin ThomasHammer BurkhardBorkenhagen SebastianSchneider ChristofMaahsen KlausWehrle inproceedings 2024-wagner-acns-aggregate 2024 3 5 https://www.comsys.rwth-aachen.de/fileadmin/papers/2024/2024-wagner-mac-aggregation.pdf 22nd International Conference on Applied Cryptography and Network Security (ACNS '24), Abu Dhabi, UAE Abu Dhabi, UAE International Conference on Applied Cryptography and Network Security (ACNS) March 5-9, 2024 accepted 10.1007/978-3-031-54773-7_10 1 EricWagner MartinSerror KlausWehrle MartinHenze poster 2024-fink-sul 2024 3 5 19 ven2us VDE ETG/FNN-Tutorial 2024 Schutz- und Leittechnik, March 05-06, 2024, Leipzig, Germany Leipzig, Germany VDE ETG/FNN-Tutorial 2024 Schutz- und Leittechnik March 05-06, 2024 1 Ina BereniceFink MarkusDahlmanns KlausWehrle article 2024_pennekamp_supply-chain-survey ACM Computing Surveys 2024 2 1 56 2 Supply chains form the backbone of modern economies and therefore require reliable information flows. In practice, however, supply chains face severe technical challenges, especially regarding security and privacy. In this work, we consolidate studies from supply chain management, information systems, and computer science from 2010--2021 in an interdisciplinary meta-survey to make this topic holistically accessible to interdisciplinary research. In particular, we identify a significant potential for computer scientists to remedy technical challenges and improve the robustness of information flows.

However, the handling of sensitive information, in terms of (i) internal company data and (ii) the underlying algorithm to compute the benchmark, demands strict (technical) confidentiality guarantees—an aspect that existing approaches fail to address adequately. Still, advances in private computing provide us with building blocks to reliably secure even complex computations and their inputs, as present in industry benchmarks. In this paper, we thus compare two promising and fundamentally different concepts (hardware- and software-based) to realize privacy-preserving benchmarks. Thereby, we provide detailed insights into the concept-specific benefits. Our evaluation of two real-world use cases from different industries underlines that realizing and deploying secure information systems for industry benchmarking is possible with today's building blocks from private computing.

As manually creating these behavioral models is tedious and error-prone, research focuses on machine learning to train them automatically, achieving detection rates upwards of 99 %. However, these approaches are typically trained not only on benign traffic but also on attacks and then evaluated against the same type of attack used for training. Hence, their actual, real-world performance on unknown (not trained on) attacks remains unclear. In turn, the reported near-perfect detection rates of machine learning-based intrusion detection might create a false sense of security. To assess this situation and clarify the real potential of machine learning-based industrial intrusion detection, we develop an evaluation methodology and examine multiple approaches from literature for their performance on unknown attacks (excluded from training). Our results highlight an ineffectiveness in detecting unknown attacks, with detection rates dropping to between 3.2 % and 14.7 % for some types of attacks. Moving forward, we derive recommendations for further research on machine learning-based approaches to ensure clarity on their ability to detect unknown attacks. anomaly detection; machine learning; industrial control system internet-of-production, rfc https://www.comsys.rwth-aachen.de/fileadmin/papers/2022/2022-kus-iids-generalizability.pdf ACM Proceedings of the 8th ACM Cyber-Physical System Security Workshop (CPSS '22), co-located with the 17th ACM ASIA Conference on Computer and Communications Security (ASIACCS '22), May 30-June 3, 2022, Nagasaki, Japan 978-1-4503-9176-4/22/05 10.1145/3494107.3522773 1 DominikKus EricWagner JanPennekamp KonradWolsing Ina BereniceFink MarkusDahlmanns KlausWehrle MartinHenze inproceedings WagnerSWH2022 2022 5 18 201-206 /fileadmin/papers/2022/2022-wagner-bpmac.pdf ACM Proceedings of the 15th ACM Conference on Security and Privacy in Wireless and Mobile Networks (WiSec '22) San Antonio, Texas, USA 15th ACM Conference on Security and Privacy in Wireless and Mobile Networks (WiSec '22) 978-1-4503-9216-7/22/05 10.1145/3507657.3528554 1 EricWagner MartinSerror KlausWehrle MartinHenze inproceedings 2022-lorenz-ven2us 2022 Power grids are increasingly faced with the introduction of decentralized, highly volatile power supplies from renewable energies and high loads occurring from e-mobility. However, today’s static grid protection cannot manage all upcoming conditions while providing a high level of dependability and security. It forms a bottleneck of a future decarbonizing grid development. In our research project, we develop and verify an adaptive grid protection algorithm. It calculates situation dependent protection parameters for the event of power flow shifts and topology changes caused by volatile power supplies due to the increase of renewable generation and the rapid expansion of e-mobility. As a result the distribution grid can be operated with the optimally adapted protection parameters and functions for changing operating states. To safely adjust the values on protection hardware in the field, i.e., safe from hardware failures and cyberattacks, we research resilient and secure communication concepts for the adaptive and interconnected grid protection system. Finally, we validate our concept and system by demonstrations in the laboratory and field tests. ven2us Proceedings of the CIRED workshop on E-mobility and power distribution systems 2022, June 2-3, 2022, Porto, Portugal Porto CIRED workshop on E-mobility and power distribution systems 2022 June 2-3, 2022 10.1049/icp.2022.0768 1 MatthiasLorenz Tobias MarkusPletzer MalteSchuhmacher TorstenSowa MichaelDahms SimonStock DavoodBabazadeh ChristianBecker JohannJaeger TobiasLorz MarkusDahlmanns Ina BereniceFink KlausWehrle AndreasUlbig PhilippLinnartz AntigonaSelimaj ThomasOffergeld proceedings fink-lcn-demons-2021 2021 10 4 nerd-nrw https://www.comsys.rwth-aachen.de/fileadmin/papers/2021/2021-fink-lcn-demons.pdf IEEE online Edmonton, Canada 46th IEEE Conference on Local Computer Networks (LCN) October 4-7, 2021 10.1109/LCN52139.2021.9524879 1 Ina BereniceFink MartinSerror KlausWehrle inproceedings 2021-glebke-service-based-forwarding 2021 6 10 reflexes /fileadmin/papers/2021/2021-glebke-service-based-forwarding.pdf IEEE Proceedings of the 2021 IEEE International Conference on High Performance Switching and Routing: Workshop on Semantic Addressing and Routing for Future Networks (SARNET-21) 978-1-6654-4005-9 2325-5609 10.1109/HPSR52026.2021.9481814 1 RenéGlebke DirkTrossen IkeKunze DavidLou JanRüth MirkoStoffers KlausWehrle inproceedings 2021-kunze-signal-detection 2021 6 10 internet-of-production https://www.comsys.rwth-aachen.de/fileadmin/papers/2021/2021-kunze-signal-detection.pdf IEEE Proceedings of the 2021 IEEE 30th International Symposium on Industrial Electronics (ISIE) 978-1-7281-9023-5 2163-5145 10.1109/ISIE45552.2021.9576221 1 IkeKunze PhilippNiemietz LiamTirpitz RenéGlebke DanielTrauth ThomasBergs KlausWehrle inproceedings 2021-kunze-coordinate-transformation 2021 5 11 334-340 in-network computing; latency; approximation internet-of-production,reflexes https://www.comsys.rwth-aachen.de/fileadmin/papers/2021/2021-kunze-coordinate-transformation.pdf IEEE Proceedings of the 4th IEEE International Conference on Industrial Cyber-Physical Systems (ICPS '21) 978-1-7281-6207-2 10.1109/ICPS49255.2021.9468247 1 IkeKunze RenéGlebke JanScheiper MatthiasBodenbenner Robert H.Schmitt KlausWehrle inproceedings 2021_dahlmanns_entrust 2021 4 28 78–87 The ongoing digitization of industrial manufacturing leads to a decisive change in industrial communication paradigms. Moving from traditional one-to-one to many-to-many communication, publish/subscribe systems promise a more dynamic and efficient exchange of data. However, the resulting significantly more complex communication relationships render traditional end-to-end security futile for sufficiently protecting the sensitive and safety-critical data transmitted in industrial systems. Most notably, the central message brokers inherent in publish/subscribe systems introduce a designated weak spot for security as they can access all communication messages. To address this issue, we propose ENTRUST, a novel solution for key server-based end-to-end security in publish/subscribe systems. ENTRUST transparently realizes confidentiality, integrity, and authentication for publish/subscribe systems without any modification of the underlying protocol. We exemplarily implement ENTRUST on top of MQTT, the de-facto standard for machine-to-machine communication, showing that ENTRUST can integrate seamlessly into existing publish/subscribe systems. cyber-physical system security; publish-subscribe security; end-to-end security internet-of-production, rfc https://www.comsys.rwth-aachen.de/fileadmin/papers/2021/2021-dahlmanns-entrust.pdf ACM Proceedings of the 1st ACM Workshop on Secure and Trustworthy Cyber-Physical Systems (SaT-CPS '21), co-located with the 11th ACM Conference on Data and Application Security and Privacy (CODASPY '21), April 26-28, 2021, Virtual Event, USA Virtual Event, USA ACM Workshop on Secure and Trustworthy Cyber-Physical Systems April 28, 2021 978-1-4503-8319-6/21/04 10.1145/3445969.3450423 1 MarkusDahlmanns JanPennekamp Ina BereniceFink BerndSchoolmann KlausWehrle MartinHenze phdthesis 2021-serror-phd-thesis 2021 3 https://www.shaker.de/de/content/catalogue/index.asp?ISBN=978-3-8440-7923-4 Shaker Verlag

Due to a competitive environment, this process imposes strong privacy needs, as leaked business secrets can have devastating effects on participating companies. Consequently, related work proposes to protect sensitive input data of companies using secure multi-party computation or homomorphic encryption. However, related work so far does not consider that also the benchmarking algorithm, used in today's applied real-world scenarios to compute all relevant statistics, itself contains significant intellectual property, and thus needs to be protected. Addressing this issue, we present PCB — a practical design for Privacy-preserving Company Benchmarking that utilizes homomorphic encryption and a privacy proxy — which is specifically tailored for realistic real-world applications in which we protect companies' sensitive input data and the valuable algorithms used to compute underlying key performance indicators. We evaluate PCB's performance using synthetic measurements and showcase its applicability alongside an actual company benchmarking performed in the domain of injection molding, covering 48 distinct key performance indicators calculated out of hundreds of different input values. By protecting the privacy of all participants, we enable them to fully profit from the benefits of company benchmarking. practical encrypted computing; homomorphic encryption; algorithm confidentiality; benchmarking; key performance indicators; industrial application; Internet of Production internet-of-production https://www.comsys.rwth-aachen.de/fileadmin/papers/2020/2020-pennekamp-company-benchmarking.pdf https://eprint.iacr.org/2020/1512 HomomorphicEncryption.org Proceedings of the 8th Workshop on Encrypted Computing & Applied Homomorphic Cryptography (WAHC '20), December 15, 2020, Virtual Event Virtual Event December 15, 2020 978-3-00-067798-4 10.25835/0072999 1 JanPennekamp PatrickSapel Ina BereniceFink SimonWagner SebastianReuter ChristianHopmann KlausWehrle MartinHenze proceedings fink-lcn-demons-2020 2020 11 15 nerd-nrw https://www.comsys.rwth-aachen.de/fileadmin/papers/2020/2020-fink-lcn-mud-smartphone.pdf IEEE online Sydney, Australia 45th IEEE Conference on Local Computer Networks (LCN) November 16-19, 2020 10.1109/LCN48667.2020.9314782 1 Ina BereniceFink MartinSerror KlausWehrle inproceedings 2020-dahlmanns-imc-opcua 2020 10 27 101-110 Due to increasing digitalization, formerly isolated industrial networks, e.g., for factory and process automation, move closer and closer to the Internet, mandating secure communication. However, securely setting up OPC UA, the prime candidate for secure industrial communication, is challenging due to a large variety of insecure options. To study whether Internet-facing OPC UA appliances are configured securely, we actively scan the IPv4 address space for publicly reachable OPC UA systems and assess the security of their configurations. We observe problematic security configurations such as missing access control (on 24% of hosts), disabled security functionality (24%), or use of deprecated cryptographic primitives (25%) on in total 92% of the reachable deployments. Furthermore, we discover several hundred devices in multiple autonomous systems sharing the same security certificate, opening the door for impersonation attacks. Overall, in this paper, we highlight commonly found security misconfigurations and underline the importance of appropriate configuration for security-featuring protocols. industrial communication; network security; security configuration internet-of-production, rfc https://www.comsys.rwth-aachen.de/fileadmin/papers/2020/2020-dahlmanns-imc-opcua.pdf ACM Proceedings of the Internet Measurement Conference (IMC '20), October 27-29, 2020, Pittsburgh, PA, USA Pittsburgh, PA, USA ACM Internet Measurement Conference 2020 October 27-29, 2020 978-1-4503-8138-3/20/10 10.1145/3419394.3423666 1 MarkusDahlmanns JohannesLohmöller Ina BereniceFink JanPennekamp KlausWehrle MartinHenze article serror-iiotsec-tii-2020 IEEE Transactions on Industrial Informatics 2020 9 11 17 5 2985-2996 nerd-nrw https://comsys.rwth-aachen.de/fileadmin/papers/2020/2020-serror-tii-iiotsec.pdf https://ieeexplore.ieee.org/document/9195014 online 1941-0050 10.1109/TII.2020.3023507 1 MartinSerror SachaHack MartinHenze MarkoSchuba KlausWehrle inproceedings 2020-kirchhof-wowmom-ccncps 2020 8 31 internet-of-production, reflexes https://comsys.rwth-aachen.de/fileadmin/papers/2020/2020-kirchhof-wireless-mac-improvements.pdf IEEE Computer Society online International Symposium on a World of Wireless, Mobile and Multimedia Networks: Workshop on Communication, Computing, and Networking in Cyber Physical Systems (WoWMoM-CCNCPS'2020), August 31 - September 3, 2020, Cork, Ireland Cork, Ireland August 31 - September 3, 2020 10.1109/WoWMoM49955.2020.00068 1 Jörg ChristianKirchhof MartinSerror RenéGlebke KlausWehrle inproceedings 2020-serror-networking-qwin 2020 6 21 consent https://comsys.rwth-aachen.de/fileadmin/papers/2020/2020-serror-qwin.pdf https://ieeexplore.ieee.org/abstract/document/9142792 IFIP online Proceedings of the 19th IFIP Networking 2020 Conference (NETWORKING '20), June 22-26, 2020, Paris, France Paris, France IFIP NETWORKING Conference June 22-26, 2020 978-3-903176-28-7 1 MartinSerror EricWagner RenéGlebke KlausWehrle inproceedings 2020-mann-ur-weldseamstudy 2020 6 https://www.comsys.rwth-aachen.de/fileadmin/papers/2020/2020-mann-weld-seam-geometry-control.pdf Proceedings of the 2020 Internal Conference on Ubiquitous Robots Internal Conference on Ubiquitous Robots June 22-26, 2020 10.1109/UR49135.2020.9144839 1 SamuelMann RenéGlebke IkeKunze DominikScheurenberg RahulSharma UweReisgen KlausWehrle DirkAbel inproceedings 2020_roepert_opcua 2020 4 2 To address the increasing security demands of industrial deployments, OPC UA is one of the first industrial protocols explicitly designed with security in mind. However, deploying it securely requires a thorough configuration of a wide range of options. Thus, assessing the security of OPC UA deployments and their configuration is necessary to ensure secure operation, most importantly confidentiality and integrity of industrial processes. In this work, we present extensions to the popular Metasploit Framework to ease network-based security assessments of OPC UA deployments. To this end, we discuss methods to discover OPC UA servers, test their authentication, obtain their configuration, and check for vulnerabilities. Ultimately, our work enables operators to verify the (security) configuration of their systems and identify potential attack vectors. internet-of-production, rfc https://www.comsys.rwth-aachen.de/fileadmin/papers/2020/2020-roepert-opcua-security.pdf en University of Tübingen Proceedings of the 1st ITG Workshop on IT Security (ITSec '20), April 2-3, 2020, Tübingen, Germany Tübingen, Germany April 2-3, 2020 10.15496/publikation-41813 1 LinusRoepert MarkusDahlmanns Ina BereniceFink JanPennekamp MartinHenze inproceedings 2019-glebke-in-network-cv 2019 12 9 reflexes,maki,internet-of-production https://www.comsys.rwth-aachen.de/fileadmin/papers/2019/2019-glebke-in-network-cv.pdf Online ACM 1st ACM CoNEXT Workshop on Emerging in-Network Computing Paradigms (ENCP '19) en 978-1-4503-7000-4/19/12 10.1145/3359993.3366646 1 RenéGlebke JohannesKrude IkeKunze JanRüth FelixSenger KlausWehrle book 2019-stoffers-dissertation 2019 10 Discrete Event Simulation; Parallelization; Memoization memosim https://www.shaker.de/de/content/catalogue/index.asp?ISBN=978-3-8440-6973-0 Klaus Wehrle Shaker Reports on Communications and Distributed Systems en 978-3-8440-6973-0 1 MirkoStoffers thesis 2019-fink-ma 2019 6 Communication and Distributed Systems, RWTH Aachen University, Germany Master Thesis 1 Ina BereniceFink inproceedings 2019_pennekamp_infrastructure 2019 5 8 31-37 New levels of cross-domain collaboration between manufacturing companies throughout the supply chain are anticipated to bring benefits to both suppliers and consumers of products. Enabling a fine-grained sharing and analysis of data among different stakeholders in an automated manner, such a vision of an Internet of Production (IoP) introduces demanding challenges to the communication, storage, and computation infrastructure in production environments. In this work, we present three example cases that would benefit from an IoP (a fine blanking line, a high pressure die casting process, and a connected job shop) and derive requirements that cannot be met by today’s infrastructure. In particular, we identify three orthogonal research objectives: (i) real-time control of tightly integrated production processes to offer seamless low-latency analysis and execution, (ii) storing and processing heterogeneous production data to support scalable data stream processing and storage, and (iii) secure privacy-aware collaboration in production to provide a basis for secure industrial collaboration. Based on a discussion of state-of-the-art approaches for these three objectives, we create a blueprint for an infrastructure acting as an enabler for an IoP.

At the same time, multi-core systems have become the de facto standard hardware platform. Unfortunately, wireless systems pose a particular challenge for parallel execution due to a tight coupling of network entities in space and time. Moreover, model developers are often domain experts with no in-depth understanding of parallel and distributed simulation. In combination, both aspects severely limit the performance and the efficiency of existing parallelization techniques. We address these challenges by presenting parallel expanded event simulation, a novel modeling paradigm that extends discrete events with durations which span a period in simulated time. The resulting expanded events form the basis for a conservative synchronization scheme that considers overlapping expanded events eligible for parallel processing. We furthermore put these concepts into practice by implementing Horizon, a parallel expanded event simulation framework specifically tailored to the characteristics of multi-core systems. Our evaluation shows that Horizon achieves considerable speedups in synthetic as well as real-world simulation models and considerably outperforms the current state-of-the-art in distributed simulation.

To this end, independent events have to be identified to enable their simultaneous execution. Hence, the number of events identified as independent needs to be maximized in order to increase the level of parallelism. Traditionally, dependencies are determined only by time and location of events: If two events take place on the same simulation entity, they must be simulated in timestamp order. Our approach to overcome this limitation is to also investigate data-dependencies between events. This enables event reordering and parallelization even for events at the same simulation entity. To this end, we design the simulation language PSimLa, which aids this process. In this paper, we discuss the PSimLa design and compiler as well as our data-dependency analysis approach in detail and present case studies of wireless network models, speeded up by a factor of 10 on 12 cores where time-based parallelization only achieves a 1.6x speedup.

In contrast to traditional applications, the focus is on carrying out communication at very short latencies together with high reliabilities. Meeting such extreme requirements with wireless networks is challenging. A potential candidate for such a network is a token-passing protocol, as it allows to bound latencies. However, it lacks mechanisms to cope with the dynamics of wireless channels. In this paper, we present EchoRing, a novel wireless token-passing protocol. Cooperative communication and an improved fault tolerance allow this decentralized protocol to support industrial applications over wireless networks. Based on experimental results, we demonstrate the suitability of EchoRing to support demands of industrial applications. EchoRing outperforms other schemes by several orders of magnitude in terms of reliability for latencies of and below 10ms.

However, it is currently not possible to investigate BitTorrent with ns-3 due to the unavailability of an according application model. In this paper we eliminate this burden. We present a highly modular BitTorrent model which allows for the easy simulation of different BitTorrent systems such as file sharing as well as present and future BitTorrent-based Video-on-Demand systems.

A primary concern is the considerable amount of parallelization overhead imposed on the event handling routines of the simulation framework. Besides more complex event scheduling algorithms, the main sources of overhead are thread synchronization and locking of shared data structures. As a result, the overhead of parallelization may easily outweigh the benefits of parallelization in comparison to classic sequential simulation. We introduce two efficient event handling schemes based on our parallel-simulation extension Horizon for the OMNeT++ simulator.First, we present a \emph{push-based event handling scheme} to minimize the overhead of thread synchronization and locking. Second, we complement this scheme with a novel \emph{event scheduling algorithm} that significantly reduces the overhead of parallel event scheduling. Lastly, we prove the correctness of our scheduling algorithm. Our evaluation reveals a total reduction in the event handling overhead of up to 16x when combining both schemes. horizon fileadmin/papers/2011/2011-kunz-horizon-omnetworkshop.pdf Online ICST
