What Is the Adaptive Network?
Since the introduction of the first Public Switched Telephone Network, networks have continually evolved. Through the various stages of development—from fixed endpoints in the early Internet to today’s broadband networks that connect mobile users to massive data centers and bandwidth behemoths like Netflix, Amazon, and Facebook—networks have adjusted to accommodate new demands.
The once-static infrastructure is undergoing a more profound transformation than ever before. The latest incarnation is autonomous networking, which is a trend that has been building for some time. The autonomous network runs without much human intervention. It can configure, monitor and maintain itself independently.
But, even though it’s a significant advance, autonomous networking is still too restrictive and too rigid. So Ciena has defined a new approach to the evolution of networking—the Adaptive Network—that’s geared toward providing a network that can grow with a company as its business needs and markets change.
The Adaptive Network is remaking the network into a dynamic, programmable infrastructure built on analytics and automation.
The Adaptive Network allows providers to evolve their current infrastructures into more of a communications loop that relays information from network elements, instrumentation, users, and applications to a software layer for review, analysis, and action—rather than bogging down the network itself.
The Adaptive Network includes three important layers:
- Programmable infrastructure: This includes the network’s physical and virtual elements, as well as the telemetry gathered from them. The programmable infrastructure layer is highly intelligent and interprets data so the network can make decisions—whether that means routing traffic around a circuit that's down or investigating and correcting an issue with latency or lower-than-expected capacity on a specific link. Programmable infrastructure requires a flexible grid; a reconfigurable photonic layer to give the ability to reroute channels of variable spectral occupancy across any path, and across any optical spectrum in the network; and telemetry from the IP layer correlated with routing data. In addition, a programmable infrastructure needs tunable coherent transponders to efficiently map a flexible number of client signals to the variable line capacity. In turn, that requires a centralized purpose-built Optical Transport Network (OTN) or packet switching architecture.
- Analytics and intelligence: The programmable infrastructure produces significant amounts of data. Some of it is big data that indicate trends that the network learns and adjusts for over time. Big data can inform the network on how to adjust in the long term, which traffic patterns to look out for, and which parts of the network could be vulnerable. Then there’s small data—things that are happening at a fairly rapid pace. It could be a flicker on a circuit or an immediate request from a customer. Such events require a speedy response from the network, and those moves will be made by the analytics. But once the decisions have been made, a human operator or pre-defined policies could step in and approve or change things as necessary. In a truly autonomous network, there would be no operator influence at this point.
- Software control and automation: Research shows the undisputed number one cause of network outages is human error, with estimates as high as 32 percent, according to Dimension Data's 2014 Network Barometer report. Effective automation of network tasks, such as loading access controllers and provisioning routers, or automated calculation and configuration of TE tunnels to optimize traffic and relieve congestion, can eliminate those errors and keep the network running at peak performance. The ability for automation to work across multiple vendors is critical. Some technologies are good at working with one set of devices from a single vendor, but few networks are built on a single vendor’s gear. Networks have to interoperate, using APIs, to function efficiently and move data efficiently and swiftly from point to point.
The development of the Adaptive Network is a watershed moment for the networking world. It’s a cohesive evolution that supports all aspects of intelligent automation—such as intent-based orchestration, analytics, and programmable domain control. It’s a microservices-based architecture that delivers extensibility and scale. Plus, it takes a DevOps integration approach to provide operational and service agility.
The Adaptive Network is a new approach that expands on autonomous networking concepts to transform the static network into a dynamic, programmable environment driven by analytics and intelligence.
