  1. 1. Enabling Fast and Accurate Run-Time Decisions in Geo-Distributed Systems : Better Achieving Service Level Objectives

    Författare :Kirill Bogdanov; Dejan Kostic; Gerald Q. Maguire Jr.; Bill Yoshimi; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cloud Computing; Geo-Distributed Systems; Replica Selection Algorithms.; Molntjänster; Geodistribuerade system; Valalgoritmer för replikas; Datalogi; Computer Science;

    Sammanfattning : Computing services are highly integrated into modern society and used  by millions of people daily. To meet these high demands, many popular  services are implemented and deployed as geo-distributed applications on  top of third-party virtualized cloud providers. However, the nature of  such a deployment leads to variable performance. LÄS MER

    Sammanfattning : Data-centers increasingly deploy commodity servers with high-speed network interfaces to enable low-latency communication. However, achieving low latency at high data rates crucially depends on how the incoming traffic interacts with the system's caches. When packets that need to be processed in the same way are consecutive, i.e. LÄS MER

  5. 5. NFV Service Chains at the Speed of the Underlying Commodity Hardware

    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NFV; service chains; synthesis; offloading; tagging; zero inter-core communication; line-rate; 100GbE; NFV; tjänstekedjor; syntetisering; processavlastning; paketmärkning; ingen inter-CPU-kommunikation; länkkapacitet; 100GbE; Datalogi; Computer Science; Informations- och kommunikationsteknik; Information and Communication Technology; Telecommunication; Telekommunikation;

    Sammanfattning : Link speeds in networks will in the near-future reach and exceed 100 Gbps. While available specialized hardware can accommodate these speeds, modern networks have adopted a new networking paradigm, also known as Network Functions Virtualization (NFV), that replaces expensive specialized hardware with open-source software running on commodity hardware.
