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.

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.

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.

Wireless Backhaul Network Solutions Enabled by Ciena's Carrier Ethernet Service Delivery 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 CESD portfolio, Ciena has found a way to maximize the value of Carrier Ethernet for successful backhaul services.

High-Quality Carrier Ethernet Services using Metro Packet Optical Transport (pdf)
To capture and retain the most discerning high-value enterprise customers, contain costs, and maximize profitability in the face of heavy competition, service providers must replace or augment first-generation, standalone Ethernet switches and basic Ethernet-over-SONET/SDH solutions with a more scalable, manageable, and deterministic service architecture.

Dynamic Wavelength Routing: The Sensible Approach to ROADM (pdf)
ROADM systems add an all-optical switching capability to the network that can be extremely valuable to carriers. The agility to switch, drop, and add traffic at the optical layer becomes more important as service bandwidth profiles approach the 10 or 40 Gb/s data rates of a wavelength. Ciena's CN 4200 ROADM saves immediate capital expense and provides the scalability to defer the cost of adding bandwidth on the network.

Wholesale Optical Services (pdf)
Today’s wholesale optical services market is driven by two fundamental factors. First, IXCs with long-haul WDM infrastructure that offer Metro-to-Metro connectivity but do not have direct access to all customer buildings. Second, LECs—particularly competitive service providers and even cable MSOs—that offer managed optical services within their Metro networks but cannot attract large enterprise accounts because they are unable to offer services between Metro regions. Ciena’s Wholesale Optical Services solution breaks both the cost and bandwidth barriers of traditional solutions with high-speed, highly scalable, carrier-grade optical Ethernet. Based on the CN 4200™ FlexSelect™ Advanced Services Platform, ITU G.709 compliant OTU Digital Wrapper technology allows the Ciena solution to transparently manage other protocols across the network on a single wavelength.
