Diseño y optimización de una red GPON a través de una red SDN para la Facultad Técnica para el Desarrollo.

Abstract

Descriptive, inductive and deductive research to implement a design that allows the optimization of a GPON (Gigabitcapable Passive Optical Network) access network through the SDN (Software Designed Network) scenario for the Facultad de Educación Técnica para el Desarrollo of the University Católica Santiago de Guayaquil (UCSG) in order to generate benefits for internal and external users of this place. To know the initial requirements, the current proposal that remains within the network was analyzed, knowing that the main problems are due to the lack of coverage and network operability. For the design, the network was structured in such a way that it consists of an external part, where the basic structures of a GPON network were implemented as an OLT (Optical Line Terminal) and an internal part where the selected ONTs (Optical Network Terminal) are highlighted. To cover the necessary requirements and from the SDN point of view, the OpenFlow protocol and a controller with Open DayLight were used to be able to configure the necessary structure and efficiently manage the network resources. To determine the quality of the GPON network, a device known as GPONDoctor was used and in the devices that were conditioned according to the SDN protocol, the Floodlight application was used, which allows to modify the aspects related to quality. Subsequently, the final design was presented to analyze the characteristics offered by each of the elements used and generate the appropriate budget to manage the purchase with the managers.
