  2. 21. Performance modeling and control of web servers

    Author : Mikael Andersson; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis deals with the task of modeling a web server and designing a mechanism that can prevent the web server from being overloaded. Four papers are presented. The first paper gives an M/G/1/K processor sharing model of a single web server. The model is validated against measurements ands imulations on the commonly usedw eb server Apache. READ MORE

  4. 22. Markov Decision Problems in ATM Traffic Control

    Author : Ernst Nordström; Lars Asplund; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Systems; Datorteknik;

    Abstract : This thesis discusses how to make cost-effective use of the communication resources in the Broadband Integrated Services Digital Network (B-ISDN), which is based on the Asynchronous Transfer Mode (ATM) switching and multiplexing technique.The thesis deals with two important functions in ATM traffic control, namely Call Admission Control (CAC) and routing, which affects both the network operator's revenue over time and the users' Quality of Service (QOS) and Grade of Service (GOS).

  5. 23. Error and Traffic Control for High-Speed Networks

    Author : Henrik Lundqvist; Gunnar Karlsson; Shivkumar Kalyanaraman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telecommunication; Telekommunikation;

    Abstract : The Internet evolves rapidly, both in terms of the applications that use it and the networks that carry the traffic. This creates many important research tasks, both to adapt the networks that carry the traffic to work well together with the Internet protocols and to make the protocols robust to tolerate various underlying networks.

  6. 24. Active Resource Management in Middleware and Service-oriented Architectures

    Author : Niklas Widell; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikationsteknik; Telecommunication engineering; Intelligent Networks; TINA; web systems; distributed systems; resource allocation; stochastic optimization; simulation models; performance analysis; overload control; load balancing;

    Abstract : In this thesis, we study load balancing and overload control in two distributed architectures: Distributed Object Computing (DOC) systems and Services-oriented Architecture (SOA) systems. While DOC and SOA have differences in terms of implementation, they are similar from a performance viewpoint. READ MORE
