From jan.kofron at d3s.mff.cuni.cz Tue Oct 4 09:24:29 2016 From: jan.kofron at d3s.mff.cuni.cz (Jan Kofron) Date: Tue, 4 Oct 2016 09:24:29 +0200 Subject: Seminar today Message-ID: <1f06b37b-d9d6-fa61-e21f-dbacdb933ccc@d3s.mff.cuni.cz> Dear all, Let me invite you to the seminar of Dept. of Software Engineering, which takes place today at 14:00 in S8. Since the topic is highly related to research of our IoT/sCPS group, I believe that some of you might find it interesting. The title and abstract are attached below. Have a nice rainy day! Jan ============= Kien A. Hua (Department of Computer Science, University of Central Florida) Surging Demand for Internet Bandwidth: Challenges and Opportunities =================================================================== Multimedia computing and communications are core technologies for many important applications, including the Internet of Things (IoT), cyber-physical systems, intelligent transportation systems, computer-aided medical image diagnosis, social media, and entertainment, to name a few. In particular, multimedia applications are known to be data intensive; as such, efficient data transport and delivery mechanisms to move multimedia content through networks such as the Internet are active areas of research. In this talk some pioneering works that provided early solutions for video-on-demand applications that inspired subsequent research are presented, followed with discussion about new challenges and emerging solutions. In particular, a new concept in network communications - traffic deduplication - is introduced. It addresses increasing stress on the Internet due to the surge of video streaming traffic. Emerging IoT applications, projected to exceed over 28 billion connected devices such as cameras and sensors, by the year 2020 pose another great challenge. While cloud computing has successfully supported many big data applications at data centers, it is ineffective for IoT applications that deal with entirely different kinds of big data. To overcome this new challenge, edge computing is emerging as an effective solution, in which small computing facilities, such as small data centers, are placed at the edge of the Internet in close proximity to the Internet of Things. This Internet computation paradigm runs counter to the theme of consolidation and massive data centers that has dominated the discourse on cloud computing. ThingStore, presented in this talk, is an IoT applications development and deployment platform based on the edge computing strategy. While an IoT environment fusing human and machine intelligence opens a host of new opportunities, the human teams may be overwhelmed trying to keep up with the real-time information. This calls for more effective communication and collaboration management tools in order for the human teams to deal with information overload in realtime decision making. Tabletop, a multimedia conferencing system presented in this talk, is one such environment to support teamwork in an IoT environment. Prof. Kien A. Hua is a Pegasus Professor and Director of the Data Systems Lab at the University of Central Florida, U.S.A. He was the Associate Dean for Research of the College of Engineering and Computer Science at UCF. Prior to joining the university, he was a Lead Architect at IBM Mid-Hudson Laboratory, where he led a team of senior engineers to develop a highly parallel computer system, the precursor to the highly successful commercial parallel computer known as SP2. Currently, Prof. Hua is also serving as a domain expert on spaceport technology at NASA.

This talk will delve into how the Hotmail team instrumented their storage stack to determine how and when data could be de-duplicated. We’ll go one step further by going over the de-duplication logic developed, how we ensure data won’t be lost, and how it runs at the internet scale we needed. You’ll get to see real code, understand more about the Microsoft cloud architecture, and go behind the scenes on how our development process works. Speaker: Principal Group Program Manager for OneDrive – John Rodrigues was born and raised in California, near San Francisco. He attended college at the University of California where he received his undergraduate degree in 2002. Shortly after graduating, he joined Microsoft at their Silicon Valley location, working on the Hotmail platform for over 11 years. As a director of engineering, he oversaw an overhaul of the storage, mobile, and abuse platforms so the product could scale to the ever-changing needs and expectations of customers. Today, he is a group manager on the OneDrive team and is responsible for helping to evolve our cloud storage and productivity suites.
