1. 6. Networked Latency Sensitive Applications - Performance Issues between Cloud and Edge

   Författare :Lorenzo Corneo; Per Gunningberg; Christian Rohner; Jussi Kangasharju; Anna Brunström; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Latency Sensitive Applications; Cloud Computing; Edge Computing; Internet Measurements; Age of Information;

   Sammanfattning : The increasing demand for industrial automation has motivated the development of applications with strict latency requirements, namely, latency-sensitive applications. Such latency requirements can be satisfied by offloading computationally intensive tasks to powerful computing devices over a network at the cost of additional communication latency. LÄS MER

3. 7. 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 :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cloud Computing; Geo-Distributed Systems; Replica Selection Algorithms.; Molntjänster; Geodistribuerade system; Valalgoritmer för replikas; Computer Science; Datalogi;

   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

4. 8. Performance problem diagnosis in cloud infrastructures

   Författare :Olumuyiwa Ibidunmoye; Erik Elmroth; Guilliano Casale; Viktoria Fodor; Henrik Björklund; Umeå universitet; []
   Nyckelord :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;

   Sammanfattning : 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.

5. 9. Wideband integrated circuits for optical communication systems

   Författare :Stavros Giannakopoulos; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical interconnects; SiGe HBT; receiverfront-end; VCSEL driver; wideband amplifiers; data communication; InP DHBT; TIA; distributed amplifiers.;

   Sammanfattning : The exponential growth of internet traffic drives datacenters to constantly improvetheir capacity. Several research and industrial organizations are aiming towardsTbps Ethernet and beyond, which brings new challenges to the field of high-speedbroadband electronic circuit design. LÄS MER

7. 10. Broadband Receiver Electronic Circuits for Fiber-Optical Communication Systems

   Författare :Stavros Giannakopoulos; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photodetector; broadband amplifiers; data communication; VCSEL; distributed amplifiers.; receiver front-end; short-haul interconnects; InP DHBT; SiGe HBT; TIA;

   Sammanfattning : The exponential growth of internet traffic drives datacenters to constantly improve their capacity. As the copper based network infrastructure is being replaced by fiber-optical interconnects, new industrial standards for higher datarates are required. LÄS MER
