Users’ ever-increasing expectations—and the technology breakthroughs that continue to feed them—have created an unprecedented level of pressure and complexity for today’s network providers. Some strategic approaches suggest that complexity is the enemy, and that a fully automated network is the answer. Ciena takes a broader view. We believe a network, just like the humans who invented it, must grow smarter, more agile, and more responsive every day. We believe network providers must strive to achieve a more adaptive network. This paper explains our vision for the Adaptive Network.
