Modern computer networks and communication systems are increasing in size, scope, and heterogeneity. The promise of a single end-to-end technology has not been realized and likely never will occur. The decreasing cost of bandwidth is increasing the possible applications of computer networks and communication systems to entirely new domains. Problems in integrating heterogeneous wired and wireless technologies, ensuring security and quality of service, and reliably operating large-scale systems including the inclusion of cloud computing have all emerged as important topics.

  1. REVERSEPTP: A clock synchronization scheme for software-defined networks

    This paper introduces REVERSEPTP, a clock synchronization scheme for software-defined networks (SDN). REVERSEPTP is based on the Precision Time Protocol (PTP), but is conceptually reversed; in REVERSEPTP all nodes (switches) in the network distribute timing information to a single software-based central node (the SDN controller) that tracks the state of all the clocks in the network. In accordance with the SDN paradigm, the ‘brain’ is implemented in software, making REVERSEPTPflexible and programmable from an SDN programmer's perspective.

  2. Seamless integration of cloud and fog networks

    A way to merge cloud computing infrastructures with traditional or legacy network deployments, by extending virtualized network segments towards the fog and having pluggable interfaces to support any kind of network device that can be remotely configured. Provisioning times can be reduced when using legacy equipment, by centralizing and automating control and configuration, with migration to full SDN-based deployments done iteratively and in tandem with existing deployments.

  3. Effective network management via dynamic network anomaly visualization

    One of the biggest challenges of managing large-scale dynamic networks is the ability to make sense of and identify the causes of potentially bad activities from a large amount of log data. To that end, we designed and implemented a network log data visualization tool to analyze network anomalies. In particular, our link anomaly graphs augmented by link anomaly detection algorithms, together with other views such as parallel coordinates, tree maps, and Gantt charts, can effectively analyze hard-to-find anomalies in dynamic networks.

  4. A flexible information service for management of virtualized software-defined infrastructures

    Lefteris Mamatas, Stuart Clayman and Alex Galis

    Version of Record online: 15 JUL 2016 | DOI: 10.1002/nem.1943

    The paper introduces and presents the design details of the virtual infrastructure information service, a new management information handling framework that (i) provides logically centralized information flow establishment, optimization, coordination, synchronization and management with respect to the diverse management and control entity demands, (ii) is designed according to the characteristics and requirements of software-defined networking and network function virtualization and (iii) inter-operates with our own virtualized infrastructure framework. It includes evaluation results demonstrating its flexible and adaptable behaviour.

  5. An adaptive Paris Metro Pricing scheme for mobile data networks

    Huai-Sheng Huang, Shu-Chiung Hu, Po-Han Lee and Yu-Chee Tseng

    Version of Record online: 15 JUL 2016 | DOI: 10.1002/nem.1941

    In this paper, we propose an adaptive PMP scheme, so-called APMP, which determines the dynamic access prices of different classes for the next 24 h. The accessible prices should try to increase the revenue while operators can serve more subscribers. Our simulation results show that APMP can significantly improve total revenue and average revenue per user for the operator.
