Provision, manage, and program networks more rapidly with software-defined networking. In this centralized approach to network management, the underlying network infrastructure is abstracted from applications. SDN provides choice in automation and programmability across data centers, campuses, and wide-area networks. See how SDN is the foundation for automating the complete network lifecycle with intent-based networking.
Software-defined networking (SDN) is an architecture designed to make a network more flexible and easier to manage. SDN centralizes management by abstracting the control plane from the data forwarding function in the discrete networking devices.
An SDN architecture delivers a centralized, programmable network and consists of the following:
SDN has seen wide adoption across data centers (64%), WANs (58%), and access networks (40%). For more information on SDN trends, see the 2020 Global Networking Trends report.
SDN serves as a foundational element of a comprehensive intent-based networking (IBN) architecture. SDN has been limited to automated provisioning and configuration. IBN now adds "translation" and "assurance" so you can automate the complete network lifecycle and continuously align the network to business needs. Watch our Beyond SDN webinar recording to explore more ways intent is changing how we network.
Reduce complexity by decoupling the control and data planes, while making automation highly secure and scalable.
Deploy applications and services faster by leveraging open APIs. Easily integrate third-party products.
Eliminate manual configuration. Provision and manage data centers, campuses, and wide-area networks.
Centralize configuration, management, control, monitoring, service delivery, and cloud automation.
Montana State University has powered up intent-based networking and improved scalability with Cisco Software-Defined Access and Cisco Digital Network Architecture.
Durham County has automated data center services and policies, so engineers can spend less time managing the data center network and more time focusing on strategic initiatives.
