2. 1. Realizing High Performance NFV Service Chains

   Author : Georgios P. Katsikas; Dejan Kostic; Gerald Maguire Jr.; Fabian Schneider; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NFV; service chains; profiler; scheduling; multiplexing; synthesis; line-rate; 40 Gbps; NFV; service kedjor; profilering; planläggningsstrategier; syntetiserade; 40 Gbps; Informations- och kommunikationsteknik; Information and Communication Technology; Computer Science; Datalogi;

   Abstract : Network functions (NFs) hold a key role in networks, offering in-network services, such as enhanced performance, policy enforcement, and security. Traditionally, NFs have been implemented in specialized, thus expensive hardware. READ MORE

4. 2. Performance, Isolation and Service Guarantees in Virtualized Network Functions

   Author : Muhammad Siraj Rathore; Peter Sjödin; Markus Hidell; Andrea Bianco; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NFV; virtual router; service guarantee; scheduling; rate control; Computer Science; Datalogi;

   Abstract : A network is generally a collection of different hardware-based network devices carrying out various network functions, (NF). These NF implementations are special purpose and expensive. Network function virtualization (NFV) is an alternative which uses software-based implementation of NFs in inexpensive commodity servers. READ MORE

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

   Author : Georgios P. Katsikas; Dejan Kostic; Gerald Q. Maguire Jr.; Rebecca Steinert; Fabian Schneider; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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; Computer Science; Datalogi; Informations- och kommunikationsteknik; Information and Communication Technology; Telecommunication; Telekommunikation;

   Abstract : 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.

6. 4. Improving user comprehension and entertainment in wireless streaming media : introducing cognitive quality of service

   Author : Greger Wikstrand; Lars-Erik Janlert; Jerry Eriksson; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Multicast channels; Quality of Service; Cognitive QoS; Wireless LAN; Multiaccess Communication; IEEE 802.11; Displays; Mobile Communications; Video Coding; Tracking; Animation; Cognitive Psychology; Experience Design; Computer science; Datavetenskap;

   Abstract : In future mobile networks service quality might be poor. A new measure is needed to be able to assess services in terms of their effectiveness and usefulness despite their lacking visual appeal. Cognitive Quality of Service is a way to measure the effectiveness in use of a networked service. READ MORE

7. 5. Food Service and Nutritional Care in Swedish Elderly Care : The Progress of National Actions and their Local Interpretations

   Author : Malin Skinnars Josefsson; Ylva Mattsson Sydner; Margaretha Nydahl; Anne Marie Beck; Uppsala universitet; []
   Keywords : food service; nutritional care; elderly care; national actions; municipality; questionnaire; registry data; Kostvetenskap; Food; Nutrition and Dietetics;

   Abstract : The main aim of this thesis is to study local level outcomes regarding food service and nutritional care in Swedish elderly care in relation to the progress of national actions. Study I compared results from a repeated national survey using a questionnaire investigating the general structure and organisation of food service in elderly care. READ MORE
