  - Year 2009

  In the paper analytical model for calculating burst loss probabilities for the combination of two service differentiation schemes for OBS network namely: extended offset time based scheme and PPS (Preemption Priority Schemes) is revised. Moreover authors introduce analytical model for calculating burst loss probabilities for an optical path when OBS network employs both service differentiation schemes and JET signaling. The comparison...

  Testowanie rzeczywistych urządzeń IP QoS wymaga źródeł ruchu o różnych charakterystykach ruchowych i informacyjnych umożliwiających przeprowadzenie badań dla skrajnych obciążeń. Równoznaczne to jest z generowaniem strumieni pakietów o dużych przepływnościach. Profesjonalne generatory sprzętowe są bardzo drogie i często dla pełnego przeprowadzenia badań konieczny jest zestaw większej liczby takich generatorów. Rozwiązaniem może...

  Publication

  • S. Kaczmarek
  • P. Kostecki

  - Year 2007

  In the paper analytical models of two service differentiation schemes for optical burst switched network: extended offset time based and PPS (Preemptive Priority Scheme) are revised. Also accordance of analytical models for those schemes is studied when complete class isolation is assumed. Furthermore authors introduce an analytical model which describes an effective degree of isolation when burst switched network employs both...
