The contributions are related with resource allocation during pon operation and with the upgrade process to allocate more capacity to the network in an as-needed fashion. We first address algorithms for dynamic bandwidth allocation (dba) in the upstream channel of ethernet-based pons through providing a state-of-the-art survey and proposing two algorithms. The proposed dba results demonstrate improved performance and fairness among users. Then we introduce the problem of allocating new capacity to an  existing pon through addition of wavelength (channels) and line-rate upgrades. In this regard, we first analyze possible strategies for pon evolution, and then we provide a new cost-based method to optimize the upgrade process in a per-period basis. The results on pon evolution analysis and our capacity-upgrade method contribute to cost reductions while optimizing new channel allocation, maximizing network capacity usage, and assuring minimum disturbances.    esta tesis es el resultado de contribuciones para optimizar o mejorar la distribuci\u00f3n de recursos en redes \u00f3pticas pasivas (pons).  las contribuciones est\u00e1n relacionadas con el uso de los recursos durante la operaci\u00f3n de las pons y con el proceso de incremento en la capacidad en la red de forma gradual. Primero enfocamos el estudio en algoritmos de distribuci\u00f3n din\u00e1mica de ancho de banda (dba, por las siglas en ingl\u00e9s) sobre el canal ascendente de las redes pon basadas en ethernet, para lo cual proveemos un resumen del estado del arte y proponemos dos nuevos algoritmos. Los resultados de evaluar los dba propuestos demuestran mejoras en el rendimiento y mayor justicia entre los usuarios. Posteriormente se introduce el problema de asignar m\u00e1s capacidad a una pon existente mediante la implementaci\u00f3n de nuevas longitudes de onda (canales) y aumento de la tasa de l\u00ednea. Finalmente se plantea un m\u00e9todo que minimiza las inversiones en el proceso de migraci\u00f3n de las redes pon. Los resultados en el an\u00e1lisis de la evoluci\u00f3n de las pons y nuestro m\u00e9todo basado en costos para incrementar la capacidad, contribuyen a reducir la inversi\u00f3n a la vez que se optimiza la implementaci\u00f3n y asignaci\u00f3n de nuevos canales, maximizando el uso de la capacidad de la red, y asegurando m\u00ednimos cortes de servicios.<\/p>\n<p>&nbsp;<\/p>\n<h3>Datos
