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.

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.

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.

Carrier Ethernet: Taking Bandwidth to the Edge
(pdf)
As demand explodes for voice, video and data services, and as the number of users of those services surges, government agencies are taxed with finding ways to cost-effectively get as much bandwidth as possible to the users at the network edge. Faced with the need to upgrade their network infrastructures, agencies are opting to move away from aging TDM technologies such as ATM. One new method rapidly attracting organizations is Carrier Ethernet.

Storage Extension Network Solutions: Lower-cost, Higher-Performance Networks
(pdf)
Robust, secure, resilient, high-capacity storage networks are business imperatives. The right network solutions must provide reliable, timely, and accurate application-layer replication over a network that cost-effectively delivers high-performance connectivity to fit application requirements. This white paper explores techniques to ensure the availability of storage applications over distances while driving costs down by up to 70 percent.

Achieving Cost Savings and Compliance with a Green IT Network
(pdf)
Reducing an organization’s carbon footprint requires the implementation of virtualized IT solutions, as well as migration of many applications and workloads to cloud computing to dramatically increase efficiency and use less power. Advances in technology now make it possible to transport more traffic while consuming less power per bit. Ciena’s 6500 Packet-Optical Transport Platform, for example, runs at 100 Gb/s—reducing carbon emissions by a factor of two when compared to 10 Gb/s network platforms.
