Cisco has introduced a versatile and broad approach to network programmability Cisco Open Network Environment (Cisco ONE) aimed at helping customers drive the next wave of business innovation through trends such as cloud, mobility, social networking, and video. Cisco ONE enables flexible, application driven customization of network infrastructures to help realize business objectives such as increased service velocity, resource optimization, and faster monetization of new services.

The Cisco Open Network Environment is delivered through a rich set of platform APIs, agents and controllers, and overlay network technologies. Cisco ONE complements current approaches to software defined networking while encompassing the entire solution stack from transport to management and orchestration. With Cisco's Open Network Environment customers can harness the intelligent network through programmability and abstraction across multiple layers, offering a choice of protocols, industry standards, and usage based deployment models.

As part of the Open Network Environment, Cisco announced One Platform Kit (onePK) which provides application programming interfaces (APIs) for developers across Cisco operating systems: Cisco IOS , IOS-XR, and NX-OS. Cisco also announced proof of concept controller software and proof of concept OpenFlow agent for Software Defined Networking (SDN) research.  Cisco is also enabling scalable virtual overlay networks for multi-tenant cloud deployments with the Cisco Nexus 1000V virtual switch. New innovations include OpenStack support, programmability, multi-hypervisor capability, and VXLAN gateway functionality.

Cisco is collaborating on emerging network technologies with industry leaders, academic organizations, and standards bodies to meet their heterogeneous requirements for network programmability. Cisco's Open Network Environment supports a wide variety of deployment models including:

· Universities and Research Organizations Network partitioning or "campus network slicing" using proof of concept  controller software and OpenFlow agents for SDN research

· Hyperscale Data centers: Network flow management with programmatic access via APIs

· Cloud Providers: Automated provisioning and programmable overlay network for scalable multi-tenancy

· Service Providers: Programmatic access, policy and analytics to optimize and monetize service delivery

· Enterprises: Private cloud automation for virtual workloads, including VDI.
