  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. Hybrid Routing in Next Generation IP Networks : QoS Routing Mechanisms and Network Control Strategies

    Author : Antoine B Bagula; Björn Pehrson; Bukhard Stiller; KTH; []

    Abstract : Communication networks have evolved from circuit-switched and hop-by-hop routed systems into hybrid data/optical networks using the Internet as a common backbone carrying narrow- and broad-band traffic offered by a multitude of access networks. This data/optical backbone is built around a multi-technology/multi-protocol routing architecture which runs the IP protocols in a collapsed IP stack where ATM and SONET/SDH have been replaced by the suite of Generalized Multiprotocol Label Switching (GMPLS) protocols.

  3. 3. Experimental multiuser secure quantum communications

    Author : Jan Bogdanski; Mohamed Bourennane; Nobuyuki Imoto; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Quantum key distribution; multiparty quantum secret sharing; Sagnac interferometer; “plug play” QKD; Passive Optical Network PON ; decoy states; single mode fiber birefringence compensation; quantum bit error rate; visibility; Physics; Fysik; Physics; fysik;

    Abstract : We are currently experiencing a rapid development of quantum information, a new branch of science, being an interdisciplinary of quantum physics, information theory, telecommunications, computer science, and many others. This new science branch was born in the middle of the eighties, developed rapidly during the nineties, and in the current decade has brought a technological breakthrough in creating secure quantum key distribution (QKD), quantum secret sharing, and exciting promises in diverse technological fields.

  4. 4. Fiber-Optic Interconnections in High-Performance Real-Time Computer Systems

    Author : Magnus Jonsson; Högskolan i Halmstad; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Fiber-optic communication; Real-time communication; Computer engineering; Datorteknik;

    Abstract : Future parallel computer systems for embedded real-time applications,where each node in itself can be a parallel computer, are predicted to havevery high bandwidth demands on the interconnection network. Otherimportant properties are time-deterministic latency and guarantees to meetdeadlines. READ MORE
