A User-Oriented Performance Comparison of Video Hosting Services
Computer Communications 116 (2018) 118–131 Contents lists available at ScienceDirect Computer Communications journal homepage: www.elsevier.com/locate/comcom A user-oriented performance comparison of video hosting services T ⁎ Alessio Botta ,a,b, Aniello Avallonea, Mauro Garofaloa, Giorgio Ventrea,b a University of Napoli Federico II, Napoli, Italy b NM2 srl, Napoli, Italy ARTICLE INFO ABSTRACT Keywords: Internet streaming is responsible for a significant fraction of Internet traffic. It has been reported to account up to Network neutrality 70% of peak traffic in North American fixed access networks, and this figure is expected to reach 80% by Internet video streaming 2020 [1]. Regarding such a killer service of the Internet, much has been discussed regarding if and how video Network performance hosting providers violate or may violate neutrality principles, in order to give users a “better” service compared to their competitors or other services. In this paper, we provide a contribution to this discussion studying three video hosting providers (i.e. YouTube, Vimeo, and Dailymotion). Specifically, we analyze their delivery infra- structures, including where the servers that provide videos are located, and the performance from a user viewpoint. To assess the performance, we measure throughput and RTT as experienced by users watching real videos of different popularity from several locations around the world and at different day hours. We uncover the performance differences of these providers as a function of the different variables under control and move a step forward to understand what causes such differences. We also study the changes in the infrastructures and related performance over time, performing different measurement campaigns over different years. -

MOBILE SMART FUNDAMENTALS MMA MEMBERS EDITION NOVEMBER 2014 messaging . advertising . apps . mcommerce www.mmaglobal.com NEW YORK • LONDON • SINGAPORE • SÃO PAULO MOBILE MARKETING ASSOCIATION NOVEMBER 2014 REPORT Measurement & Creativity Thoughts for 2015 Very simply, mobile marketing will continue to present the highest growth opportunities for marketers faced with increasing profitability as well as reaching and engaging customers around the world. Widely acknowledged to be the channel that gets you the closest to your consumers, those marketers that leverage this uniqueness of mobile will gain competitive footholds in their vertical markets, as well as use mobile to transform their marketing and their business. The MMA will be focused on two cores issues which we believe will present the biggest opportunities and challenges for marketers and the mobile industry in 2015: Measurement and Creativity. On the measurement side, understanding the effectiveness of mobile: the ROI of a dollar spent and the optimized level for mobile in the marketing mix will become more and more critical as increased budgets are being allocated towards mobile. MMA’s SMoX (cross media optimization research) will provide the first-ever look into this. Additionally, attribution and understanding which mobile execution (apps, video, messaging, location etc…) is working for which mobile objective will be critical as marketers expand their mobile strategies. On the Creative side, gaining a deeper understanding of creative effectiveness cross-screen and having access to case studies from marketers that are executing some beautiful campaigns will help inspire innovation and further concentration on creating an enhanced consumer experience specific to screen size. We hope you’ve had a successful 2014 and we look forward to being a valuable resource to you again in 2015. -
A View from the Edge: a Stub-AS Perspective of Traffic Localization
A View From the Edge: A Stub-AS Perspective of Traffic Localization and its Implications Bahador Yeganeh Reza Rejaie Walter Willinger University of Oregon University of Oregon NIKSUN, Inc. [email protected] [email protected] [email protected] Abstract—Serving user requests from near-by caches or servers to implement their business model for getting content closer has been a powerful technique for localizing Internet traffic with to the end users. For example, while Akamai [1] operates and the intent of providing lower delay and higher throughput to maintains a global infrastructure consisting of more then 200K end users while also lowering the cost for network operators. This basic concept has led to the deployment of different types of servers located in more than 1.5K different ASes to bring the infrastructures of varying degrees of complexity that large CDNs, requested content by its customers closer to the edge of the ISPs, and content providers operate to localize their user traffic. network where this content is consumed, other CDNs such Prior measurement studies in this area have focused mainly on as Limelight or EdgeCast rely on existing infrastructure in revealing these deployed infrastructures, reverse-engineering the the form of large IXPs to achieve this task [2]. Similar to techniques used by these companies to map end users to close- by caches or servers, or evaluating the performance benefits that Akamai but smaller in scale, major CPs such as Google and “typical” end users experience from well-localized traffic.

Students' Behavior and Perceptions Regarding Complementary Videos
applied sciences Article Students’ Behavior and Perceptions Regarding Complementary Videos for Introductory Physics Courses in an Online Environment Antoni Perez-Navarro 1,2,* , Victor Garcia 1 and Jordi Conesa 1 1 Faculty of Computer Sciences, Multimedia and Telecomunication, Universitat Oberta de Catalunya (UOC), Rambla del Poblenou, 156, 08018 Barcelona, Spain; [email protected] (V.G.); [email protected] (J.C.) 2 eLearn Center, Universitat Oberta de Catalunya (UOC), Rambla del Poblenou, 156, 08018 Barcelona, Spain * Correspondence: [email protected] Featured Application: This works can help to choose the better and more efficient videos for professors of Physics courses. Abstract: Digital videos have an important and increasing presence in student learning. They play a key role especially in subjects with high mathematical content, such as physics. However, creating videos is a time-consuming activity for teachers, who are usually not experts in video creation. Therefore, it is important to know which kinds of videos are perceived as more useful by students and why. In this paper we analyze students’ perception of videos in an introductory physics course of engineering with over 200 first year students in a 100% online university, Universitat Oberta de Catalunya (UOC). Students had 142 videos available of several types. We followed a qualitative methodology from a ground theory perspective and performed semi-structured interviews. Results show that students found videos as the most valued resource, although they considered that videos cannot substitute text documents. Students valued human elements and found them in videos Citation: Perez-Navarro, A.; Garcia, where the hands of the professor appear. Finally, students consumed videos according to the course V.; Conesa, J. -
