Cisco Extensible Network Controller (XNC) Developer Center

Site updated on 24th February 2014 with XNC V1.5 downloads.

Software Defined Networking (SDN) is an approach to programmable networks that separates and abstracts the control-plane functions from the network devices and places them in a centralized controller. To accommodate adoption of SDN in both existing (brownfield) and new (greenfield) networks, Cisco has taken a hybrid approach. In this approach, some traditional control-plane functions will continue to exist in the network devices for conventional network operations, and some will be extracted to a centralized external controller to accommodate SDN solutions. Cisco Extensible Network Controller (XNC) addresses these requirements and emerging trends by providing much greater automation and orchestration of the network fabric, and by allowing dynamic, application-driven configuration of networks and services.
