Subscribers are excited about new high-value services such as IPTV, video on demand and new mobile device applications. These new services along with social networking websites and user-generated content are creating a need for additional bandwidth delivery at the network edge. However, existing long-haul networks can become a bottleneck to profitably delivering these services end-to-end.

Challenges

Today's core is still too inefficient and bandwidth-limited. As new services at the edge become increasingly popular, network operators need to increase capacity, while simultaneously offering more cost-effective core capabilities to keep service margins strong. Furthermore, these services are increasingly being delivered over 40G IP router ports, requiring 40G connectivity in the core network. Network operators need an approach that leverages existing infrastructure investments while reducing OPEX and CAPEX.

Solution

To successfully support high-growth services across the core, operators must converge packets and circuits onto an underlying agile WDM layer, with MPLS and intelligent SONET/SDH/OTN providing the unifying structure. Combining intelligent multiservice switching systems with high-capacity transport platforms allows you to optimize traffic flows for efficient wavelength utilization, providing the lowest cost service delivery available today. In-service upgrades to 40G wavelengths allow you to scale your existing network seamlessly, employing similar engineering rules used for 10G. Ethernet and 40G client ports provide new service offerings enhancing revenue potential. Ciena enables optimized reliability and fiber capacity at the network core for transport applications, while allowing new services for cost-effective, flexible and scalable networks.
