  1. 1. Distributed Coded Caching with Application to Content Delivery in Wireless Networks

    Author : Jesper Pedersen; Chalmers University of Technology; []
    Keywords : machine learning; erasure correcting codes; optimization; Caching; device-to-device communication; content delivery networks; time-to-live;

    Abstract : The amount of content downloaded to mobile devices, mainly driven by the demand for video content, threatens to completely congest wireless networks and the trend of ever increasing video traffic is expected to continue unabated for many years. A promising solution to this problem is to store popular content closer to end users, effectively trading expensive bandwidth resources for affordable memory, a technique known as caching. READ MORE

  2. 2. Leveraging Existing Microarchitectural Structures to Improve First-Level Caching Efficiency

    Author : Ricardo Alves; David Black-Schaffer; Stefanos Kaxiras; Mattan Erez; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Energy Efficient Caching; Memory Architecture; Single Thread Performance; First-Level Caching; Out-of-Order Pipelines; Instruction Scheduling; Filter-Cache; Way-Prediction; Value-Prediction; Register-Sharing.;

    Abstract : Low-latency data access is essential for performance. To achieve this, processors use fast first-level caches combined with out-of-order execution, to decrease and hide memory access latency respectively. READ MORE

  3. 3. Study on Decentralized Machine Learning and Applications to Wireless Caching Networks

    Author : Yu Ye; Ming Xiao; Zhu Han; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Distributed multi-task learning; decentralized optimization; ADMM; mobility-aware wireless caching; Distribuerat lärande med flera uppgifter; decentraliserad optimering; ADMM; mobilitetsmedveten trådlös cache; Electrical Engineering; Elektro- och systemteknik;

    Abstract : To promote the development of distributed machine learning, it is crucial to provide efficient models and training algorithms. This thesis is devoted to the design of distributed multi-task learning and decentralized algorithms, as well as the application of distributed machine learning in wireless caching networks.

  4. 4. Network overload avoidance by traffic engineering and content caching

    Author : Henrik Abrahamsson; Mats Björkman; Bengt Ahlgren; Luca Muscariello; Mälardalens högskola; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; Computer Science; datavetenskap;

    Abstract : The Internet traffic volume continues to grow at a great rate, now driven by video and TV distribution. For network operators it is important to avoid congestion in the network, and to meet service level agreements with their customers. READ MORE

  5. 5. A System, Tools and Algorithms for Adaptive HTTP-live Streaming on Peer-to-peer Overlays

    Author : Roberto Roverso; Seif Haridi; Jim Dowling; Alberto Montresor; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; peer-to-peer; distributed caching; nat traversal; congestion control; adaptive HTTP streaming; live streaming; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : In recent years, adaptive HTTP streaming protocols have become the de facto standard in the industry for the distribution of live and video-on-demand content over the Internet. In this thesis, we solve the problem of distributing adaptive HTTP live video streams to a large number of viewers using peer-to-peer (P2P) overlays. READ MORE
