Cisco eXtensible Network Controller (XNC)
Cisco XNC is a Java OSGI-based application built to support the scalability, extensibility and modularity required for rapidly evolving enterprise IT architectures. It is the industry's first controller that supports multiple protocols, both OpenFlow and Cisco onePK for device communication. The Service Abstraction Layer (SAL) in the XNC architecture enables modular device support through either OpenFlow or Cisco onePK by abstracting the protocols from applications that run on the controller. As an extensible platform, other southbound protocol plugins could be added as the technology evolves. On the northbound, XNC provides Java OSGI and REST API support for business applications to interact. Using Java, OSGI application developers could easily extend or develop applications that will run on the controller itself. REST API can be used by business applications that are outside the controller, and for those XNC supports both secure and non-secure communication mechanism.
Cisco's SDN strategy should become clearer Nov. 6, when the company reportedly plans to unveil the products from its Insieme Networks venture.
