The amount of data that networks have to support continues to grow exponentially, driven by ultra-mobile users who want the ability to access the cloud and consume high-definition content, video, and applications when and where they choose. This need for constant network availability without outages puts incredible strain on legacy transport networks. Migrating from a fixed- to a flex-grid photonic network architecture—and the new operational paradigm this entails—can seem overwhelming. However, Ciena has the appropriate hardware, software, and services to enable a seamless migration process.
