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.

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.

Packet Transport Evolution
(pdf)
When it comes to packet transport, one single solution is hardly an answer for all carriers’ needs, given the diversity of their subscribers’ requirements and the legacy of their installed base. In addition to the cost of the solution, packet transport also must address the transparency and the unique characteristics of the transport network. Ciena’s Intelligent Infrastructure allows the combination of several transport technologies—including Coherent 40G/100G and 1T—to provide a complete toolset for the most efficient and comprehensive packet transport architecture, with the agility, efficiency, and cost-effectiveness suited for carrier needs for years to come.
