Survivable Optical Networks with foreword by Ovum RHK (pdf)
Globalization and natural disasters have combined to rejuvenate interest in global communications networks, particularly the undersea networks interconnecting with their terrestrial counterparts. As these networks grow and customer needs evolve, mesh protection of undersea links is emerging as an important trend at the optical network layer as operators look to control costs while improving network resiliency.

Evolution to the 100G Transport Network (pdf)
Carriers are challenged by bandwidth constraints while attempting to accommodate demands for high-speed services. The aggregation of 10GbE on IP routers, coupled with fiber plant exhaust, necessitates 100 Gb/s ports on DWDM equipment and 100GbE ports for switch-to-switch interconnection. This white paper explains how Ciena leads the development of timely, technically innovative 100 Gb/s solutions that operate over existing 10 Gb/s infrastructures.

Ovum RHK White Paper: OTN Emerges as a Must Have (pdf)
OTN, the Optical Transport Network, dates back to 1998, but is only now hitting its stride as a requirement for next-generation optical network elements. OTN was one of many promising optical technologies whose rollout was delayed by post-bubble investment declines. As network operators have begun spending again, and as service bandwidths and transport pipes are getting larger, OTN has reemerged as a “must have” technology, but not for the lofty reasons many often cite.

IDC White Paper: Making the Case for Next-Generation Transport Networks (pdf)
Convergence is a popular buzzword in industry discussions today. New technologies that were not available a few years ago are enabling convergence in new ways. Clearly, convergence of networks and various network elements saves money on equipment for NSPs, and, thus, contributes to cost reductions. However, NSPs must converge their networks with their customers, and the future demands of their network, in mind. And it’s important to note that converged solutions can support legacy services as well as new services and offer a migration path to the all-packet architecture of the future.

Adaptive WAN: Enabling Web Services, Networked Remote Storage and Grid Computing (pdf)
Three tremors on the IT landscape (Web Services, Networked Remote Storage and Grid Computing) are triggering an exponential growth in inter-site traffic. Organizations will need to react proactively by moving from multiple dedicated single-application networks to a more flexible, adaptable network architecture—an Adaptive WAN. This paper looks at how Web Services, Networked Remote Storage and Grid Computing are driving the need for Adaptive WANs. The paper explains how Ciena’s Adaptive WAN approach provides enterprises a simpler lower cost means to reliably extend their current and developing mission critical applications between sites, over both copper and optical lines. Various scenarios are examined.

Adaptive WANs for Enterprise and Government (pdf)
Web Services, Remote Storage Replication and Grid Computing, individually and collectively, are triggering exponential growth in inter-site traffic. If organizations react to this growth as they have in the past—adding bandwidth incrementally and prioritizing high priority traffic during peak traffic periods—organizations will find their applications increasingly struggling and competing for congested WAN resources. Their investments in IT hardware and software will not realize the expected benefits. Adaptive WANs are critical for multiple site organizations with timesensitive applications. They enable organizations to place their IT assets anywhere—including their storage assets. Ciena’s Adaptive WAN solution is field-proven in the most demanding production networks today—carrying mission-critical traffic with a full variety of bandwidth services.
