2. 1. Performance problem diagnosis in cloud infrastructures

   Author : Olumuyiwa Ibidunmoye; Erik Elmroth; Guilliano Casale; Viktoria Fodor; Henrik Björklund; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Systems Performance; Performance anomalies; Performance bottlenecks; Cloud infrastructures; Cloud Computing; Cloud Services; Cloud Computing Performance; Performance problems; Performance anomaly detection; Performance bottleneck identification; Performance Root-cause Analysis; Computer Systems; datorteknik; Computer Science; datalogi;

   Abstract : Cloud datacenters comprise hundreds or thousands of disparate application services, each having stringent performance and availability requirements, sharing a finite set of heterogeneous hardware and software resources. The implication of such complex environment is that the occurrence of performance problems, such as slow application response and unplanned downtimes, has become a norm rather than exception resulting in decreased revenue, damaged reputation, and huge human-effort in diagnosis.

4. 2. Transport service triads in supply networks

   Author : Victor Eriksson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; performance; embeddedness; network; supply chain; service; freight; transport; triad; relationship; sustainability;

   Abstract : This doctoral thesis deals with the embeddedness of transport services in supply networks. The exchange of transport services depends on the exchange of goods since exchange of goods generates demand for transport services. READ MORE

5. 3. 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

6. 4. Performance Modelling and Simulation of Service Chains for Telecom Clouds

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

   Abstract : 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).
