Heavy Reading White Paper: Building the Next-Generation Packet-Optical Switching Network
(pdf)
The next phase of SONET/SDH to packet network migration is underway, and optical networks must evolve to meet the challenges. To do this, a renewed focus has been placed on optical switching innovations and a tighter coupling of switching and transport through element integration and a unified control plane. Meanwhile, the network must continue to support legacy SONET/SDH traffic. Also, the network and network elements must have a high degree of modularity so operators can add the features and functions they need, when they need them.

El valor de OTN para la convergencia de redes y la migración IP/Ethernet
(pdf)
En la actualidad, los operadores de redes deben convergir sus redes a fin de reducir OPEX y también eliminar CAPEX adicional innecesario en redes paralelas múltiples. La implementación de 4200 OTN de Ciena asigna todos los servicios en un conjunto común de longitudes de onda. Esto simplifica todo el proceso desde el monitoreo y la implementación hasta la reposición y la administración de capacidad.

The Network as a Programmable Service-Delivery Engine
(pdf)
Service providers face the increasing need to capitalize on the paradigm shift occurring in the ways consumers and enterprises perceive and use network services and bandwidth. To remain differentiated and valuable to end-users, providers must transition networks to service-driven and highly programmable infrastructures.

Heavy Reading White Paper: The Need for Service-Driven Networks
(pdf)
Network operators around the world are considering transforming into "next-generation telcos" to remain competitive in a drastically changing environment. This new environment presents challenges and opportunities for network operators, as well as a great deal of risk. One thing is for certain: Telecom operators that don't adapt their business models to 21st-century communications are sure to fail.

A Comparison of Next-generation 40-Gbps Technologies
(pdf)
There are many proposed optical transmission systems that offer 40 Gb/s wavelength capacity. The unbridled adoption of these solutions may well depend on the degree to which they overlay on existing DWDM 10 Gb/s links. This paper provides a description of new 40 Gb/s technologies being proposed and reveals their true compatibility with existing 10 Gb/s infrastructure.

Infonetics White Paper: Using Carrier Ethernet to Backhaul LTE
(pdf)
LTE will become the single mobile network for mobile phone and mobile broadband, adopted by most of the world in the next five to ten years. Mobile operators and backhaul transport providers are adopting IP/Ethernet backhaul as the default technology choice to cost-effectively scale instead of relying on existing TDM-based transport networks for LTE backhaul. This paper details how Carrier Ethernet solves the challenges of LTE mobile backhaul.

El camino inteligente hacia una infraestructura de habilitación de servicios
(pdf)
El aumento en la demanda de ancho de banda representa una era de cambios importantes en la forma en que se utilizan, venden y admiten en la red los servicios domésticos y empresariales. Para atender verdaderamente las demandas financieras y tecnológicas del negocio de un operador de redes, se requiere de un enfoque más personalizable y optimizado hacia la conmutación. Se trata de un enfoque que proporcione un grado de modularidad y reconfigurabilidad de hardware y software que no existe en las soluciones actuales. Esta nueva flexibilidad de conmutación, que se hace posible mediante un enfoque de reconfiguración, permitirá a los operadores de redes lograr una infraestructura de conmutación con habilitación de servicios que pueda generar un incremento en los ingresos, una reducción de los costos y, por último, una diferenciación de los servicios ofrecidos a fin de alcanzar una ventaja competitiva sostenible.

OTN Outperforms SONET/SDH
(pdf)
Cable operators’ Hybrid Fiber-Coax (HFC) plants pass within half a mile of some 80 percent of business locations. Therefore, extending the fiber plant to reach mid-sized to large businesses has never been easier or more rewarding. But what is the best way to aggregate, transport and switch the services for these customers?

Increasing the Survivability and Efficiency of Video Distribution Networks
(pdf)
Broadcasters and film and television producers face the challenge of efficiently transporting high-bandwidth video content over existing networks with the highest levels of availability. While availability is key, efficiency and the ability to transport high-quality video content are equally important. This paper describes how an intelligent infrastructure increases the survivability of broadcast networks and allows efficient and cost-effective solutions to transport high-quality, advanced video content.
