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.

Coherent Optical Processing for High-Capacity Networks
(pdf)
The paradox for today’s network providers is looming ever larger and faster: Increase available capacity for users, but do so at less cost. Equipment vendors have jumped into this issue wholeheartedly and are examining and offering a variety of techniques to solve this high-capacity bandwidth challenge. One solution in particular, pioneered by Ciena as the optimum approach and known as “coherent optical processing”, promises to help service providers solve their dilemma by allowing tremendous increases in capacity while keeping CAPEX and OPEX low.

Wireless Backhaul Network Solutions Enabled by Ciena's Carrier Ethernet Solutions Portfolio
(pdf)
Mobile operators must reduce the cost-per-bit of data transport in the backhaul network while continuing to provide greater bandwidth for new high-speed data services, ensure voice quality, maintain carrier-grade OAM and provide circuit-like resilience. Carrier Ethernet technology provides a solution to these backhaul problems. With its CES portfolio, Ciena has found a way to maximize the value of Carrier Ethernet for successful backhaul services.

Delivering True Carrier Ethernet Business Services
(pdf)
A number of business trends—including the maturation of virtualization and cloud-based applications—are impacting service provider networks and service consumption. Service providers must adapt quickly in an environment where demand for services is evolving continuously, network traffic distribution is changing constantly, and bandwidth is growing continually. Pure cost reduction, although very important, is no longer sufficient; the emphasis must shift to growing top-line revenue through the creation and deployment of new Ethernet business services with greater velocity, automation, and customization.

Evolving to a Smart Grid Energy Network
(pdf)
Electric power systems constitute the fundamental infrastructure of modern society. Electric power grids and distribution networks reach virtually every home, office, factory, and institution in the industrialized world. While the basic electric grid design—based on concepts established over 75 years ago—has proven useful, its evolution has not kept up with advances in technology. Numerous pressures on the electric power delivery system are converging, forcing the system to evolve in different ways.

Economic Benefits of End-to-End OTN Service Switching
(pdf)
The unrelenting growth of bandwidth demand is causing a number of dilemmas for network operators—including how best to accommodate the need to provision higher-rate circuits, both for enterprise private-line customers and for operators’ own infrastructure for higher-layer services. End-to-end OTN service switching is the most economical way to compete for and handle the growth in high-bandwidth optical services. No other solution allows operators to turn up new services faster and more efficiently while removing the cost of uncertainty in future traffic mix.

Intelligent Submarine Solutions for an Increasingly Competitive Market
(pdf)
The international services market continues to show strong growth. According to the industry research firm, Telegeography, international Internet bandwidth has more than quadrupled in just three years—a 50 percent annual growth rate. Yet in spite of very strong demand, the industry has seen significant price erosion. In addition, customers are migrating to higher-bandwidth services, with an expectation for higher service availability and lower cost per bit, as their need for business continuity and higher total connection capacity grows. Ciena is uniquely positioned to help international operators improve the scalability, resiliency, and manageability of their undersea networks while offering the widest service portfolio.

The Common Photonic Layer
(pdf)
Common Photonic Layer (CPL) represents a significant development in the ongoing evolution to an Adaptive Optical Engine. CPL leverages years of proven expertise in developing and deploying optical network solutions and separates the optical line side from the service side. This service/photonic separation enables Ciena to deliver a highly flexible, optimized and intelligent common photonic layer to metro, regional and long-haul networks. This common approach eliminates the boundaries between each, thereby creating one converged, easy-to-operate, all-optical network.

The Strategic Imperative of an Ethernet Metro Aggregation Network
(pdf)
IP and Ethernet traffic is growing approximately 40 percent per year. Unfortunately, by 2010, broadband and wireless service revenues are projected to grow only 10 and three percent respectively. Service providers must better monetize this traffic growth while optimizing the service delivery architecture, and controlling both CAPEX and OPEX for rapidly growing and evolving IP and Ethernet services.
