Software for Your Network and Beyond
At A Glance
Innovate and develop with new networking software products, tools, and technologies that provide flexibility, new API Libraries, and consistency of features across IOS to NX-OS for better control, automation, and scale across Cisco routers, switches, servers, and more.
Consistent Features, Better Usability.
Modular components and feature consistency across our platforms (Cisco IOS, IOS-XR, and NX-OS) are at the core of our new offerings. The ability to share software and maintain consistent features while allowing for reusable code, components and more helps your business, your network, and your teams automate tasks faster and create new services or applications easier than before.
Your Network, Your Way. One Amazing Toolkit.
onePK (One Platform Kit) is Cisco's new easy-to-use development kit that combines robust features of IOS, IOS-XR, and NX-OS across Cisco routers and switches via one abstraction layer. With onePK:
- Create new or enhance existing applications and services.
- Orchestrate, manage, automate, control, and scale your current ones.
- Extend network data via APIs to new platform layers.
- onePK will be available in limited trial and to early adopters soon.
Languages You Love, Tools of Choice
The new API sets in onePK enable access to consistent features and functionality across Cisco routers, switches, servers, and more. Use the language and tools that work best for you or the project you're working on. Extend the data that your business needs from your network to new abstraction layers to improve usability, flexibility and develop applications and services faster than before.
