    • AIMD-based online MPLS traffic engineering for TCP flows via distributed multi-path routing 

      Alparslan O.; Akar, N.; Karasan, E. (Springer, 2004)
      With this paper, we propose a distributed online traffic engineering architecture for MPLS networks. In this architecture, a primary and secondary MPLS LSP are established from an ingress LSR to every other egress LSR. We ...
    • Application-specific heterogeneous network-on-chip design 

      Demirbas, D.; Akturk, I.; Ozturk, O.; Güdükbay U. (Oxford University Press, 2014)
      As a result of increasing communication demands, application-specific and scalable Network-on-Chips (NoCs) have emerged to connect processing cores and subsystems in Multiprocessor System-on-Chips. A challenge in ...
    • Available bit rate traffic engineering in MPLS networks with flow-based multipath routing 

      Akar, N.; Hökelek, İ.; Karasan, E. (Institute of Electronics Information and Communication Engineers, 2004)
      In this paper, we propose a novel traffic engineering architecture for IP networks with MPLS backbones. In this architecture, two link-disjoint label switched paths, namely the primary and secondary paths, are established ...
    • Comparative analysis of power consumption in asynchronous wavelength modular optical switching fabrics 

      Akar, N.; Eramo, V.; Raffaelli, C. (Elsevier, 2011-04-02)
      Next-generation optical routers will be designed to support the flexibility required by Future Internet services and, at the same time, to overcome the power consumption bottleneck which appears to limit throughput scalability ...
    • Design of translucent optical networks: Partitioning and restoration 

      Karasan, E.; Arisoylu, M. (Kluwer, 2004)
      We discuss the problem of designing translucent optical networks composed of restorable, transparent subnetworks interconnected via transponders. We develop an integer linear programming (ILP) formulation for partitioning ...
    • Detecting compromised routers via packet forwarding behavior 

      Mizrak, A.T.; Savage, S.; Marzullo, K. (2008)
      While it is widely understood that criminal miscreants are subverting large numbers of Internet-connected computers (e.g., for bots, spyware, SPAM forwarding), it is less well appreciated that Internet routers are also ...
    • Fault-tolerant irregular topology design method for network-on-chips 

      Tosun, S.; Ajabshir V.B.; Mercanoglu O.; Ozturk, O. (Institute of Electrical and Electronics Engineers Inc., 2014)
      As the technology sizes of integrated circuits (ICs) scale down rapidly, current transistor densities on chips dramatically increase. While nanometer feature sizes allow denser chip designs in each technology generation, ...
    • Fault-tolerant topology generation method for application-specific network-on-chips 

      Tosun, S.; Ajabshir, V. B.; Mercanoglu, O.; Ozturk, O. (Institute of Electrical and Electronics Engineers, 2015)
      As the technology sizes of integrated circuits (ICs) scale down rapidly, current transistor densities on chips dramatically increase. While nanometer feature sizes allow denser chip designs in each technology generation, ...
    • FPGA implementation of a fault-tolerant application-specific NoC design 

      Yesil, S.; Tosun, S.; Ozturk, O. (Institute of Electrical and Electronics Engineers Inc., 2016)
      Today's integrated circuits are more susceptible to permanent link failures than before as a result of diminishing technology sizes. Even a single link failure can make an entire chip useless. Single link failure problem ...
    • An ILP formulation for application mapping onto Network-on-Chips 

      Tosun, S.; Ozturk O.; Ozen, M. (2009)
      Ever shrinking technologies in VLSI era made it possible to place several modules onto a single die. However, the need for the new communication methods has also increased dramatically since traditional bus-based systems ...
    • ILP-based communication reduction for heterogeneous 3D network-on-chips 

      Akturk, I.; Ozturk, O. (IEEE, 2013)
      Network-on-Chip (NoC) architectures and three-dimensional integrated circuits (3D ICs) have been introduced as attractive options for overcoming the barriers in interconnect scaling while increasing the number of cores. ...
    • On the design of AQM supporting TCP flows using robust control theory 

      Quet, P-F.; Özbay, H. (IEEE, 2004)
      Recently it has been shown that the active queue management schemes implemented in the routers of communication networks supporting transmission control protocol (TCP) flows can be modeled as a feedback control system. ...
