  1. 36. Performance, Isolation and Service Guarantees in Virtualized Network Functions

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

    Sammanfattning : 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.

  3. 37. Wireless Broadcasting with Network Coding

    Författare :Lu Lu; Lars Kildehöj Rasmussen; Giuseppe Durisi; KTH; []
    Nyckelord :wireless broadcasting; relay-aided system; systematic binary deterministic rateless codes; random network coding; instantaneously decodable network coding;

    Sammanfattning : Wireless digital broadcasting applications such as digital audio broadcast (DAB) and digital video broadcast (DVB) are becoming increasingly popular since the digital format allows for quality improvements as compared to traditional analogue broadcast. The broadcasting is commonly based on packet transmission. LÄS MER

  4. 38. Predicting IT Governance Performance : A Method for Model-Based Decision Making

    Författare :Mårten Simonsson; Pontus Johnson; Wim Van Grembergen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; IT governance; IT governance maturity; IT governance performance; Enter-prise Architecture; Bayesian networks.; Informatics; computer and systems science; Informatik; data- och systemvetenskap;

    Sammanfattning : Contemporary enterprises are largely dependent on Information Technology (IT), which makes decision making on IT matters important. There are numerous issues that confuse IT decision making, including contradictive business needs, financial constraints, lack of communication between business and IT stakeholders and difficulty in understanding the often heterogeneous and integrated IT systems.

  5. 39. Smart Cooperation with Network Coding in Hierarchical Wireless Networks

    Författare :Nan Li; Lars Kildehöj Rasmussen; Daniel Lucani; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless communications; Hierarchical networks; 5G; Cognitive radio; Internet of Things; Cooperative communications; Spectrum sharing; Network coding; Optimization; Performance analysis.; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : To achieve more dynamic, efficient and intelligent use of the scarce wireless spectrum resource, the concept of cooperation has been formalized into several hierarchical network models in future mobile networks. Cooperative communications, such as relaying, can potentially increase communication efficiency and spectrum utilization due to the broadcast nature of wireless networks, and may lead to a better support for diverse communication modes with flexible spectrum sharing.

  7. 40. Performance Analysis of Application-Specific Multicore Systems on Chip

    Författare :Iyad Al Khatib; Axel Jantsch; Jari Nurmi; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multicore; System on Chip; Performance; Information technology; Informationsteknik;

    Sammanfattning : The last two decades have witnessed the birth of revolutionary technologies in data communications including wireless technologies, System on Chip (SoC), Multi Processor SoC (MPSoC), Network on Chip (NoC), and more. At the same time we have witnessed that performance does not always keep pace with expectations in many services like multimediaservices and biomedical applications. LÄS MER
