    Software-Defined Networks Supporting Time-Sensitive In-Vehicular Communication

    Future in-vehicular networks will be based on Ethernet. The IEEE Time-Sensitive Networking (TSN) is a promising candidate to satisfy real-time requirements in future car communication. Software-Defined Networking (SDN) extends the Ethernet control plane with a programming option that can add much value to the resilience, security, and adaptivity of the automotive environment. In this work, we derive a first concept for combining Software-Defined Networking with Time-Sensitive Networking along with an initial evaluation. Our measurements are performed via a simulation that investigates whether an SDN architecture is suitable for time-critical applications in the car. Our findings indicate that the control overhead of SDN can be added without a delay penalty for the TSN traffic when protocols are mapped properly.Comment: To be published at IEEE VTC2019-Sprin

    Yunus Abdullah - Use of Social Media by Businesses: A New opportunity For Consulting Services by Accounting Firms

    Get PDF
    In the last 10 years, social media has been restructuring business policies and practices creating new business models. These models are shaping the internal and external aspects of businesses, improving efficiency, and hopefully yielding higher profits while reducing costs. At the same time, social media is being implemented in such internal operations as employee training, recruiting, communication within organizations, and building business loyalty. Businesses are becoming more dependent on social media, making social media an inevitable expectation of effective business models. The millennial are the new generation of adults who are taking over the business world. This generation of young adults grew up using such social media networks as Facebook, Twitter, YouTube, Google +, and LinkedIn. To sustain good relationship with their clients (millennial), businesses must meet people\u27s expectation of the practices and plan their policies accordingly. This paper will examine how the use of social media by businesses is leading to a new service being offered by accounting firms, social media consulting. Experts in internal controls, accounting firms, will have the resources and capacity to offer services in social media consulting. The large accounting firms such as Deloitte, KPMG, Ernst &Young, and PWC have already entered social media consulting market.https://epublications.marquette.edu/mcnair_2013/1006/thumbnail.jp

    Mobility Study for Named Data Networking in Wireless Access Networks

    Full text link
    Information centric networking (ICN) proposes to redesign the Internet by replacing its host-centric design with information-centric design. Communication among entities is established at the naming level, with the receiver side (referred to as the Consumer) acting as the driving force behind content delivery, by interacting with the network through Interest message transmissions. One of the proposed advantages for ICN is its support for mobility, by de-coupling applications from transport semantics. However, so far, little research has been conducted to understand the interaction between ICN and mobility of consuming and producing applications, in protocols purely based on information-centric principles, particularly in the case of NDN. In this paper, we present our findings on the mobility-based performance of Named Data Networking (NDN) in wireless access networks. Through simulations, we show that the current NDN architecture is not efficient in handling mobility and architectural enhancements needs to be done to fully support mobility of Consumers and Producers.Comment: to appear in IEEE ICC 201

    A Basic Result on the Superposition of Arrival Processes in Deterministic Networks

    Full text link
    Time-Sensitive Networking (TSN) and Deterministic Networking (DetNet) are emerging standards to enable deterministic, delay-critical communication in such networks. This naturally (re-)calls attention to the network calculus theory (NC), since a rich set of results for delay guarantee analysis have already been developed there. One could anticipate an immediate adoption of those existing network calculus results to TSN and DetNet. However, the fundamental difference between the traffic specification adopted in TSN and DetNet and those traffic models in NC makes this difficult, let alone that there is a long-standing open challenge in NC. To address them, this paper considers an arrival time function based max-plus NC traffic model. In particular, for the former, the mapping between the TSN / DetNet and the NC traffic model is proved. For the latter, the superposition property of the arrival time function based NC traffic model is found and proved. Appealingly, the proved superposition property shows a clear analogy with that of a well-known counterpart traffic model in NC. These results help make an important step towards the development of a system theory for delay guarantee analysis of TSN / DetNet networks
