  1. 1. Design, analysis and simultion for optical access and wide-area networks

    Author : Jiajia Chen; Lena Wosinska; Hussein Mouftah; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber access networks; passive optical network; dynamic bandwidth allocation; reliability; switched optical networks; switching node; optical circuit switching; optical packet switching; routing and wavelength assignment; security; Telecommunication; Telekommunikation;

    Abstract : Due to the tremendous growth of traffic volume caused by both exponential increase of number of Internet users and continual emergence of new bandwidth demanding applications, high capacity networks are required in order to satisfactorily handle the extremely large amount of traffic. Hence, optical fiber communication is the key technology for the network infrastructure. READ MORE

  2. 2. Congestion Control in Packet Switching Computer Communication Networks

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

    Abstract : The objective of this research is in general to develop analytic tools for the performance study of computer networks, and is in particular motivated by a need to understand how restricted buffer sharing policies can be used for congestion control in the nodes of a packet switching computer communication network. Models of a single packet switching node with finite storage and restricted buffer sharing policies are developed. READ MORE

  3. 3. Core Switching Noise for On-Chip 3D Power Distribution Networks

    Author : Waqar Ahmad; Hannu Tenhunnen; Atila Alvandpour; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER;

    Abstract : Reducing the interconnect size with each technology node and increasing speed with each generation increases IR-drop and Ldi/dt noise. In addition to this, the drive for more integration increases the average current requirement for modern ULSI design. READ MORE

  4. 4. A study of the reliability of optical switching nodes for high capacity telecommunications networks

    Author : Lena Wosinska; KTH; []
    Keywords : ;

    Abstract : The use of optical fibers and optical network componentsallows aggregating the bit streams in order to minimize theequipment that is necessary for transmission and switching. Inthis way, however, the robustness of the network totransmission failures is decreased, i.e., number of servicesthat can be affected magnifies the effect of failure. READ MORE

  5. 5. Low power synthesis of BDD mapped circuits

    Author : Mikael Kerttu; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Abstract : Power consumption is an important design constraint for circuits used in portable devices. In this thesis an analytic approach to minimize the power dissipation of Binary Decision Diagram (BDD) mapped digital circuits is presented. READ MORE
