Putting Assured Networking to Work for Government (pdf)
The complexity of current IT networks, a shortage of skilled technical talent, and legislative challenges have slowed the pace of renovation of cumbersome, costly network infrastructures. However, top government officials recognize the need for greater visibility into network operations, along with precise real-time information to accelerate and improve decision-making.

Combining Carrier Ethernet Switching and Packet Radio Transport (pdf)
Bandwidth demand is rapidly outgrowing the inflexibility and limited capacities of traditional data transport methods, driving a significant number of worldwide operators to implement architectures based on fixed point-to-point packet radio transport solutions (microwave or millimeter wave), or a mixture of fiber and packet radio solutions.

Modernizing the Bank Branch Office Network (pdf)
Historically, bank branch offices housed and maintained their respective IT infrastructures. This was costly and highly inefficient, and created significant compliance challenges. The requirement now is for a centralized, consolidated IT architecture that connects business processes across branches to support new ways of working and greater customer focus.

Building an Assured Network (pdf)
Today’s technology-intensive environment relies on communication networks to deliver information safely among individuals and organizations. Yet, as technology has become more complex, threats against keeping information safe have also become more complex and pervasive. This paper outlines the reasons data security is a growing challenge and offers several ways network operators can build a network that is both dependable and secure.

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.

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.

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.

Maximizing LTE Benefits Using True Carrier Ethernet Backhaul (pdf)
Mobile Network Operators are evolving their wireless infrastructure to the Long Term Evolution (LTE) standard that offers low latency and high bandwidth to deliver rich content to smart mobile devices. This paper articulates the challenges and complexities in LTE design with the recommendation to use Carrier Ethernet-based solutions for backhaul from cell sites to reduce TCO. Backhaul providers can use this approach to scale their networks cost-effectively. Finally, this paper describes Ciena’s solution, which combines True Carrier Ethernet-based cell site demarcation with converged optical Ethernet aggregation to build scalable cost-effective networks.

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.

The Intelligent Path to a Service-Enabling Infrastructure (pdf)
The rise in bandwidth demand represents an era of major change in the ways residential and business services are used, sold, and supported on the network. To truly address the financial and technological imperatives of a network operator’s business, a more customizable and optimized approach to switching is required—one that provides a degree of hardware and software modularity and reconfigurability not found in today’s solutions. This new switching flexibility, made possible with a reconfigurable approach, will allow network operators to achieve a service-enabling switching infrastructure that can help drive top-line revenues, decrease costs, and ultimately differentiate offered services to achieve a sustainable competitive advantage.
