As users, devices, and distributed applications have grown in number, the networking environment has become exponentially more complex. IBN transforms a hardware-centric, manual network into a controller-led network that captures business intent and translates it into policies that can be automated and applied consistently across the network. The goal is for the network to continuously monitor and adjust network performance to help assure desired business outcomes.
IBN builds on software-defined networking (SDN), by using a network controller that acts as a central control point for network activity. Such controllers are crucial for network abstraction that lets IT treat the network as an integrated whole. Controller-led networks in all domains (including access, WAN, data center, and cloud) collaborate and extend their benefits throughout the enterprise and help make digital transformation a reality.
The closed-loop system of IBN operates with the following functional building blocks to deliver intent, or support for, the business or IT outcomes that your organization needs.
Learn what intent-based networking can do for you.
Cisco Software-Defined Access (SD-Access) automates one policy across the Cisco Catalyst wired and wireless infrastructure.
Cisco SD-WAN securely connects any user, any application, anywhere, with the power of the cloud.
Enterprise network security aligns and optimizes the network with security to thousands of locations from one interface.
"We continue to support traditional data center applications while accommodating a rapidly expanding IoT footprint, with completely different infrastructure requirements and aggressive time-to-market goals. Intent-based networking and advanced automation are essential to this transition."Jan Holzmann, Senior Manager for Central Network Services, Bosch
"Rolling out new VLANs takes minutes instead of hours, using repeatable code we know is safe. And we can implement changes or patches collectively instead of doing it manually, switch by switch. What used to take multiple days is now a hands-off, set-and-forget process."Richard Lock, Principal Infrastructure Engineer, University of Derby
"To compete with the 'big four' banks in Australia, we need to deliver better, faster services to our customers. We've cut the amount of time it takes to receive a home loan in half, and a third of our customers' loan applications are being processed within two days. Cisco technologies have been a key enabler of these improvements, and we're just getting started."Head of Enterprise Technology, Great Southern Bank
