  1. 1. Internet Video Transmission

    Author : György Dan; Gunnar Karlsson; Viktória Fodor; Jean-Yves Le Boudec; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic control; MDC; FEC; Multicast streaming; Queuing theory; Telecommunication; Telekommunikation;

    Abstract : The Internet has rapidly evolved from being a scientific experiment to a commercial network connecting millions of hosts that carries traffic generated by a large amount of applications with diverse requirements. Its architecture was however designed to enable efficient point-to-point delivery of bulk data, and can not provide statistical guarantees on the timely delivery of delay sensitive data such as streaming and real-time multimedia.

  2. 2. Disturbance Rejection and Control in Web Servers

    Author : Martin Ansbjerg Kjaer; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; feed-forward; dynamic prediction; computer systems; queuing theory; Web server;

    Abstract : An important factor for a user of web sites on the Internet is the duration of time between the request of a web page until an answer has been returned. If this response time is too long, the user is likely to abandon the web site and search for other providers of the service. READ MORE

  3. 3. Stochastic Modeling and Simulation of the TCP protocol

    Author : Jörgen Olsén; Ingemar Kaj; Joachim Charzinski; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; TCP; flow-control; network simulator; ns-2; stochastic modeling; throughput; packet loss rate; fixed-point method; Matematisk statistik; Mathematical statistics; Matematisk statistik;

    Abstract : The success of the current Internet relies to a large extent on a cooperation between the users and the network. The network signals its current state to the users by marking or dropping packets. The users then strive to maximize the sending rate without causing network congestion. READ MORE

  4. 4. Dynamic modeling of Internet congestion control

    Author : Krister Jacobsson; Håkan Hjalmarsson; Douglas Leith; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Congestion control; TCP; Control theory; Fluid flow modeling; Internet; Telecommunication; Telecommunication; Telekommunikation;

    Abstract : The Transmission Control Protocol (TCP) has successfully governed the Internet congestion control for two decades. It is by now, however, widely recognized that TCP has started to reach its limits and that new congestion control protocols are needed in the near future. READ MORE

  5. 5. Performance modeling and control of web servers

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