Provision, manage, and program networks more rapidly with software-defined networking. In this centralised approach to network management, the underlying network infrastructure is abstracted from applications. SDN provides choice in automation and programmability across data centres, campuses, and wide-area networks. Use Cisco software-defined solutions to build intent-based networks.
Reduce complexity by decoupling the control and data planes, while making automation highly secure and scalable.
Eliminate manual configuration. Provision and manage data centres, campuses, and wide-area networks.
Deploy applications and services faster by leveraging open APIs. Easily integrate third-party products.
Centralise configuration, management, control, monitoring, service delivery, and cloud automation.
Increase business agility: automate provisioning and operations, enhance security, and enable multicloud.
The University of Northampton designs, personalises, provisions, and manages its network as a single fabric across an entire campus to meet changing technology needs.
Durham County has automated data centre services and policies, so engineers can spend less time managing the data centre network and more time focusing on strategic initiatives.
Software-defined networking (SDN) is designed to make a network flexible and agile. SDN lets you design, build, and manage networks, separating the control and forwarding planes. As a result, the control plane is directly programmable, and it abstracts the underlying infrastructure for applications and network services.
Network intelligence is logically centralised through programmable SDN controllers. Implemented in software, these controllers maintain a coherent view of the network domain. To applications and policy engines, SDN looks like a single logical switch.
Software-defined networking (SDN) offers a centralised, programmable network that consists of an SDN controller, southbound APIs, and northbound APIs.
Software-defined networks have automated the process of network management.
Intent-based networking adds context, learning, and assurance capabilities by tightly coupling policy with intent. SDN can be a building block of intent-based networking.
Network function virtualisation (NFV) uses hypervisor and cloud-computing technology for network automation and orchestration. NFV works best in the context of network services (OSI Level 4 and up) that require heavy compute power, with low-to-medium bandwidth throughput.
SDN converges the management of network and application services into centralised, extensible orchestration platforms. SDN is optimal for high-throughput network forwarding (OSI Levels 0-3) where bandwidth-intensive workloads need significant traffic management.
