      Bitcoin is the first and the most extensive decentralized electronic cryptocurrency system that uses blockchain technology. It uses a peer-to-peer (P2P) network to operate without a central authority and propagate system ...

    • ClusPR: Balancing Multiple Objectives at Scale for NFV Resource Allocation 

      Woldeyohannes, Yordanos Tibebu; Mohammadkhan, Ali; Ramakrishnan, K. K.; Jiang, Yuming (Journal article; Peer reviewed, 2018)
      Network function virtualization (NFV) implements network middleboxes in software, enabling them to be more flexible and dynamic. NFV resource allocation methods can exploit the capabilities of virtualization to dynamically ...

    • Delay-Resistant Geo-Distributed Analytics 

      Mostafaei, Habib; Smaragdakis, Georgios; Zinner, Thomas Erich; Feldmann, Anja (Peer reviewed; Journal article, 2022)
      Big data analytics platforms have played a critical role in the unprecedented success of data-driven applications. However, real-time and streaming data applications, and recent legislation, e.g., GDPR in Europe, have posed ...

      Kellerer, Wolfgang; Schembra, Giovanni; Hwang, Jinho; Kamiyama, Noriaki; Kang, Joon-Myung; Martini, Barbara; Pasquini, Rafael; Pezaros, Dimitrios; Zhang, Hongke; Zhani, Mohamed Faten; Zinner, Thomas (Journal article; Peer reviewed, 2021)
      The Softwarization of networks is enabled by the SDN (Software-Defined Networking), NV (Network Virtualization), and NFV (Network Function Virtualization) paradigms, and offers many advantages for network operators, service ...

    • Guest Editors' Introduction: Special Section on Smart Management of Future Softwarized Networks 

      Schembra, Giovanni; Kellerer, Wolfgang; Jacquenet, Christian; Kamiyama, Noriaki; Martini, Barbara; Pasquini, Rafael; Pezaros, Dimitrios; Riggio, Roberto; Zhang, Hongke; Zhani, Mohamed Faten; Zinner, Thomas (Peer reviewed; Journal article, 2022)
      Network softwarization is one of the key enablers of the future Internet evolution, also supporting the road from the fifth generation (5G) to the next-generation communication systems, namely 6G, with their main objective ...

    • Including Failure Correlation in Availability Modeling of a Software-Defined Backbone Network 

      Nencioni, Gianfranco; Helvik, Bjarne Emil; Heegaard, Poul Einar (Journal article; Peer reviewed, 2017)
      Software-defined networking (SDN) promises to improve the programmability and flexibility of networks, but also brings new challenges that need to be explored. The main objective of this paper is to include failure correlation ...

    • ML-based QoE Estimation in 5G Networks Using Different Regression Techniques 

      Schwarzmann, Susanna; Marquezan, Clarissa Cassales; Trivisonno, Riccardo; Nakajima, Shinichi; Barriac, Vincent; Zinner, Thomas (Journal article; Peer reviewed, 2022)
      Monitoring and providing customers with a satisfying Quality of Experience (QoE) is a crucial business incentive for mobile network operators (MNOs). While the MNO is capable of monitoring a vast amount of network-related ...
