Case Study: Tier 1 Service Provider boosts DWDM migration speed with Ciena Services

Ciena Transforms Tier 1 Service Provider’s Multi-Vendor Network and Operational Processes

Tier 1 Service Provider Company worked with Ciena to remove a non-preferred vendor’s equipment from its live DWDM network and migrate more than 10,000 circuits to a multi-vendor next-generation network without disrupting customer service. The challenge was made harder by tight timelines, manual planning processes, and the need to keep operations and customer experience unaffected across a global network.

Ciena Services delivered a services-only transformation using a master database, custom analytics, and process autonomics to clean and integrate network data, identify viable migration paths, and automate key workflows. As a result, Tier 1 Service Provider Company reduced circuit planning time by 90%—from eight hours to one hour—and increased migration speed by more than 10x, from 10 circuits per week to over 100, while also eliminating planning fallout and improving operational efficiency for future migrations.
