1. 6. Reliable and deterministic network services

   Författare :Florian-Daniel Otel; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; queuing delay guarantees; service curve; constraint-based routing; TCP; network security; arrival curve; network failure recovery; traffic engineering; network calculus; traffic envelope;

   Sammanfattning : In a post Internet bubble economic environment the obvious lack of any disruptive new technologies that could give new impetus to network growth (as, for example, experienced after the appearance of the Web) lead to a trivialization of network services: Aside grass-roots, semi-subterranean applications like file sharing, entertainment content swapping and on-line gaming, it can be argued that network services are presently used in a manner not very different than a decade ago. In this respect, one of the factors that can be identified as limiting further development is the perceived lack of guarantees with regard to network services. LÄS MER

3. 7. Performance Modelling and Simulation of Service Chains for Telecom Clouds

   Författare :Michel Gokan Khan; Javid Taheri; Andreas Kassler; Johan Tordsson; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Performance Modelling; Performance Optimization; Performance Simulation; Network Function Virtualization; Cloud Native Computing; Computer Science; Datavetenskap;

   Sammanfattning : New services and ever increasing traffic volumes require the next generation of mobile networks, e.g. 5G, to be much more flexible and scalable. The primary enabler for its flexibility is transforming network functions from proprietary hardware to software using modern virtualization technologies, paving the way of virtual network functions (VNF).

4. 8. Network-Based Monitoring of Quality of Experience

   Författare :Junaid Junaid; Markus Fiedler; Patrik Arlos; Astrid Undheim; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Quality of Experience; Network Performance; Network measurements;

   Sammanfattning : The recent years have observed a tremendous shift from the technology-centric assessment to the user-centric assessment of network services. Consequently, measurement and modelling of Quality of Experience (QoE) attracted many contributions from researchers and practitioners. Generally, QoE is assessed via active and passive measurements.

5. 9. Performance, Availability, and Scalability in Open Networking Platforms for Internet Services

   Författare :Voravit Tanyingyong; Peter Sjödin; Markus Hidell; Raimo Kantola; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network architecture and design; Network communications; Performance; Availability; Scalability; Internet of Things IoT ; Nätverksarkitektur och design; nätverkskommunikation; prestanda; tillgänglighet; skalbarhet; sakernas internet IoT ; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Advancement in technologies brings about new demands and services. In parallel, modern commodity off-the-shelf (COTS) hardware has become very capable yet affordable. It is often used in combination with Free/Libre and Open Source Software (FLOSS) to build open networking platforms, which offer alternatives to commercial network devices. LÄS MER

7. 10. Profitability Performance of Supermarkets : The effects of scale of operation, local market conditions, and conduct on the economic performance of supermarkets

   Författare :Mikael Hernant; Högskolan i Skövde; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Retailing; Store performance; Profitability; Economies of scale; Competition; Business and economics; Ekonomi; Humaniora-samhällsvetenskap; Humanities and Social sciences;

   Sammanfattning : Ever since introduced and rolled out on the market during the 1950's and 1960's the supermarket format of grocery retail stores has played an important role in the grocery retail sector in Sweden, as well as in other countries. Although the sector in Sweden has evolved into a sector harbouring various store formats, the supermarket remains the major one - about half of the total volume of sales currently goes through supermarkets.
