On March 30, 2015, Alcatel-Lucent announced that Verizon will deploy a new optical wavelength routing technology on its U.S. ultra-long-haul network. Combined with the use of electrical switches, the new capability, available on the 1830 Photonic Service Switch (PSS), will allow Verizon to perform multilayer end-to-end service provisioning.
The new wavelength routing capability was developed with Verizon. It pairs the colorless/directionless/contentionless/flexible grid (CDC-F) ROADM capabilities of the 1830 PSS with the Wavelength Routing Engine (WRE) software suite. The WRE combines optimized versions of previously available software-based features as well as new network optimization and control features that leverage the CDC-F functions.
The Alcatel-Lucent wavelength routing capabilities are deployed on the 1830 Photonic Service Switch (PSS), which Verizon chose for its ultra-longhaul, core optical network. Verizon selected Alcatel-Lucent’s 1830 PSS converged WDM/OTN/Packet based-platform as part of its transition to an optical converged infrastructure to address traffic growth and enable faster and less expensive deployment of new services.
The wavelength routing solution consists of specialized CDC-F hardware and Wave Routing Engine (WRE) software. The WRE software provides end-to-end wavelength routing, deployment, and management capabilities. This includes unique in-band per wavelength OAM capabilities to allow for efficient monitoring of wavelength connectivity and support the rapid diagnosis and troubleshooting of potential wavelength connectivity issues, a key requirement for deploying wavelength routing in optical networks at scale.
CDC-F (Colorless Directionless Contentionless-FlexGrid) is the technology behind wavelength routing. Although the optical networking industry has been talking about the benefits of CDC-F technology for several years, this is the first solution to be deployed at scale.
Brian Fitzgerald, Senior Vice President, Global Solutions, Alcatel-Lucent said, “Operators need unlimited network dynamism and scale. A programmable IP/optical fabric is essential. Our wavelength routing technology is a foundational ingredient in providing the unparalleled flexibility with massive automation and increased efficiency that are needed in the optical layer. This solution provides unconstrained wavelength networking and can be deployed at scale.”
