  • Traffic Type Influence on Performance of OSPF QoS Routing

    Publication

    - Journal of Telecommunications and Information Technology - Year 2013

    Feasibility studies with QoS routing proved that the network traffic type has influence on routing performance. In this work influence of self-similar traffic for network with DiffServ architecture and OSPF QoS routing has been verified. Analysis has been done for three traffic classes. Multiplexed On-Off model was used for self-similar traffic generation. Comparison of simulation results was presented using both relative and non-relative...

  • Traffic Type Influence on Performance of OSPF QoS Routing

    Publication

    - Year 2012

    Feasibility studies with QoS routing proved that the network traffic type has influence on routing performance. In this work influence of self-similar traffic for network with DiffServ architecture and OSPF QoS routing has been verified. Analysis has been done for three traffic classes.

  • Current mechanisms of IGP routing - expectations and possibilities in terms of QoS constraints

    Publication

    - Year 2005

    Od mechanizmów rutingu oczekuje się nowych możliwości z chwilą wprowadzenia wymagań QoS. W tym kontekście aktualne techniki rutingu IGP nie oferuja rozwiązań określających ścieżki gwarantujące QoS. W pracy przedstawiono propozycję rozszerzenia OSPF, które umożliwia uwzględnienie ograniczeń wynikających z QoS, gwarantując jednocześnie usługi na żądanym poziomie. To rozszerzenie zawiera zarówno liniowe jak i nieliniowe metryki. Wartości...

  • Appraisement of modifications in dynamic routing protocols to support the IPng Protocol

    Publication

    - Year 2005

    W pracy, biorąc pod uwagę dynamiczny proces migracji sieci IPv4 do nowej wersji protokołu IP, przedstawiono konieczność realizacji w Internecie nowych protokołów routingu dynamicznego lub adaptacji już istniejących do nowego protokołu IPng. W artykule przedstawiono sposoby dostosowania protokołów routingu dynamicznego RIP, OSPF, BGP do nowego protokołu IP. Oceniono wpływ w/w dostosowywania na zbieżność i skalowalność protokołów...

  • The realization of ASON/GMPLS control plane

    Publication

    - Year 2010

    ASON (Automatic Switched Optical Network) is a concept of optical network recommended in G.8080/Y.1304 by ITU-T. Control Plane of this network could be based on GMPLS (Generalized Multi-Protocol Label Switching) protocols like RSVP-TE, OSPF-TE, LMP. This solution is named ASON/GMPLS. In this chapter we present the control plane problems and proposes ASON/GMPLS network realization that are tested on testbed consists of three and...

  • Traffic Type Influence on QoS Network Performance of Streaming Traffic Class

    Publication

    - Year 2013

    Feasibility study on QoS routing proved that the traffic type influence the network performance. The performance is defined here as a number of packets serviced by the network. In the paper additional element - buffers lengths used in service system was verified in terms of dependencies with routing performance. We present results obtained by simulation for many simulation scenarios. Analysis was done for two different network...
