Mozo Olea, Javier2011-02-022011-02-0220100000577352https://academica-e.unavarra.es/handle/2454/2485Contention resolution represents a challenge considered when implementing resource allocation over optical packet switching. Analytical models are proposed to optimize the behavior of different architectures and networks in terms of contention resolution and resource allocation. Asymmetries in the network traffic distribution due to the network topology induce different dimensioning results, thus different topologies are studied to quantify the required number of links and fiber delay lines. Afterwards, two contention resolution strategies are introduced to quantify the impact on the number of converters and fiber delay lines over an optical packet switching architecture. Finally, a matrix model is defined to analyze blocking situations over an optical packet switching architecture, this model seems to be very powerful to improve the efficiency of the system regarding blocking situations. Simulation results show that the proposed strategies can be utilized to improve the performance of the utilized optical packet switching architectures in terms of resource allocation.application/pdfapplication/zipengContention resolutionResource allocationOptical packet switchinginfo:eu-repo/semantics/studentThesisinfo:eu-repo/semantics/openAccess
