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 & 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.

Cisco announced One Platform Kit (onePK) which provides application programming interfaces (API) for developers across Cisco operating systems: 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 helping build 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. A "one size fits all" approach cannot support the diverse programmability requirements. Cisco’s Open Network Environment supports a wide variety of deployment models including:

• Universities and Research Organizations: Network partitioning or "campus 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

NEWS HIGHLIGHTS

One Platform Kit (onePK): software development kit for customers and partners

• onePK delivers a rich set of APIs for deep programmatic access across Cisco operating systems and hardware platforms.

• Cisco will provide phased support for onePK on IOS, IOS-XR, and NX-OS operating systems and hardware platforms including ASR, ISR G2, CRS, Catalyst and Nexus switches. Cisco onePK support will be provided initially for the ASR1000 and ISRG2.

• onePK allows tight integration with software applications for greater visibility, orchestration and control of network infrastructure for rapid service creation and delivery, and automate multiple network tasks and processes.

• With onePK, developers can select the language they are familiar with, use existing tools, and easily integrate into existing development environments.

• On June 12 Cisco announced its Cloud Connected Solution Partners and customers can also develop their own Cloud Connectors using onePK APIs to enhance and differentiate Cloud Services. Cloud Connector is a software component residing on ISR G2 and ASR1000 routing platforms to improve availability, performance, and security for cloud services.

Cisco Controller Software and OpenFlow Agents for Software Defined Networking (SDN)

• Cisco will provide proof-of-concept controller software for SDN and is collaborating with academic and research institutions in these efforts. For example, Universities will be able to partition or "slice" their campus network to enable academic research on SDN with consistent policy management.

• Cisco will provide proof-of-concept OpenFlow v1.0 agents on the Cisco Catalyst 3750-X and 3560-X Series Switches.

• Cisco is also leading several workgroups at the Open Network Foundation.

Virtual Overlay Networks extend support for OpenStack, multiple hypervisors, and VXLAN gateway functionality for consistency across physical and virtual networks

• Cisco will expand virtual overlay network solutions for scalable, multi-tenant cloud infrastructures and Infrastructure-as-a-Service (IAAS) through enhanced capabilities of its Nexus 1000V portfolio with support for open-source hypervisors. This adds to existing support for VMware and Microsoft hypervisors.

• Cisco will also provide the Virtual Extensible Local Area Network (VXLAN)  gateway to bridge traditional VLAN-based physical network environments with VXLAN-based virtual overlay networks.

• Cisco will extend vPath technology implemented on Nexus 1000V to support virtual services on VXLAN-based overlay networks, including VSG and ASA1000V. Cisco vPath will steer or "chain" traffic across VSG and ASA1000V through pre-defined policies to simplify operational workflows on a per-tenant basis.

• Cisco will offer standards-based OpenStack Quantum Plug-in and REST APIs for the Cisco Nexus 1000V virtual switch to rapidly orchestrate multi-tenant cloud infrastructures.
