CN 5060 OS: Ciena’s Fault-Tolerant, Real-Time Operating System (pdf)
Network reliability is essential to service growth. Public utility commissions and the FCC expect telecommunication services to run at all times. Carrier-class is not good enough—a true converged multiservice Carrier Ethernet/IP network should run as reliably and efficiently as non-stop telecom services, without overbuilding or chronic software pain.

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.

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.

Delivering on the Promise of Ethernet: MEF Services using Ciena's FlexSelect Architecture (pdf)
Service providers must develop a strategy for supporting Ethernet along with the existing mix of TDM, Frame Relay, and ATM services. Ciena offers a way for providers to transition those legacy offerings to an Ethernet format. Rather than continue to invest in legacy infrastructure and manage multiple types of transport networks, service providers now have a viable option for transitioning all traffic to a cost-effective, highly reliable Ethernet-based infrastructure.

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.

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.
