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

   Författare :Jiajia Chen; Lena Wosinska; Hussein Mouftah; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 2. Optimization Models and Methods for Telecommunication Networks using OSPF

   Författare :Peter Broström; Michal Pióro; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Telecommunication; OSPF; LP-duality; Polynomial methods; MATHEMATICS; MATEMATIK;

   Sammanfattning : The routing in OSPF Telecommunication networks is determined by computing shortest paths with respect to link weights set by the network operator. All shortest paths to a destination are used by the routers when traffic is routed, and the routers split the traffic evenly when alternative shortest paths exist. LÄS MER

4. 3. Dynamic Traffic Control in Multiservice Networks - Applications of Decision Models

   Författare :Ulf Ahlfors; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed-Memory Systems; Overload Control; Call Admission Control; Routing; Optimization; Multiservice Networks; Markov Decision Process; Telecommunication engineering; Telekommunikationsteknik;

   Sammanfattning : In this thesis, we develop and examine decision models intended for traffic engineering analysis of multiservice networks. Two important issues are addressed, namely call admission and routing control in multiservice broadband networks, and overload control in distributed-memory systems. LÄS MER

5. 4. On the Design of Next-Generation Routers and IP Networks

   Författare :Jing Fu; Gunnar Karlsson; Andrea Bianco; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; router architecture; IP-network architecture; Telecommunication; Telekommunikation;

   Sammanfattning : This thesis investigates distributed router architectures and IP networks with centralized control. While the current trend in IP-router architectures is towards decentralized design, there have also been research proposals for centralizing the control functions in IP networks. LÄS MER

7. 5. Towards robust traffic engineering in IP networks

   Författare :Anders Gunnar; Mikael Johansson; Steve Uhlig; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Telecommunication; Telekommunikation;

   Sammanfattning : To deliver a reliable communication service it is essential for the network operator to manage how traffic flows in the network. The paths taken by the traffic is controlled by the routing function. LÄS MER
