Resumen

RESUMEN

 

En la última década Internet ha tenido un crecimiento exponencial en el número de usuarios nuevos haciendo que las expectativas en cuanto a la calidad del servicio recibido sean evaluadas constantemente. Estas y otras exigencias constituyen la problemática principal que se relaciona con el comportamiento y desempeño en la infraestructura de las redes de acceso y tipo core definidas como soporte para las denominadas redes de próxima generación o NGN con orientación “todo IP”, es así como las propuestas en cuanto al soporte óptico desarrolladas hasta el momento, no aseguran que los resultados de su despliegue sean satisfactorios.

 

Las redes ópticas surgen como una de las tecnologías más prometedoras para cubrir la demanda en cuanto a ancho de banda, capacidad de la red, calidad de servicio y desempeño. Lo anterior se soporta en el hecho del gran número de investigaciones que se están llevando a cabo por parte de Universidades, empresas y grupos alrededor del mundo respecto a las telecomunicaciones ópticas. OBS y OPS (conmutación óptica de ráfagas y de paquetes, respectivamente) son los avances con mayor relevancia en la actualidad prometiendo una red tipo core adaptable a los requerimientos de los servicios y a los cambios en la infraestructura de la red. Los avances más recientes en estas tecnologías aseguran un mejor aprovechamiento de la infraestructura óptica existente y por desplegar, asegurando procesos completamente ópticos (conmutación y enrutamiento) con retardos mínimos jamás alcanzados hasta ahora.

 

PALABRAS CLAVES: Redes de Próxima Generación, Conmutación Óptica de Paquetes, Conmutación Óptica de Ráfagas, Calidad de Servicio y Dominio Óptico.

 


ANALYTICAL SUMMARY

 

In the last decade Internet has experienced an explosive growth due to numbers of new users as well as their expectations to quality of receiving services. These changes are major problem in core networks and the technology used so far does not assure satisfying results. Optical networks have emerged as a promising technology to fulfill growing demands on networks capacity, Quality of Service and performance. Moreover, a wide variety of technologies of fiber communication and networking are focus of research in optical telecommunication domain. Optical Packet/ Burst Switching Network (OPS/OBS) is a promising technology to present and future core networks due to best network utilization and adaptability to changes in the network infrastructure (core network).

 

KEYWORDS: Next Generation Networks, Optical Packet and Burst Switching, Quality of Service and Optical domain.
