Junos SDK Data Sheet

  1. 1. DATASHEET JUNOS SDK Product Description Product Overview The new network is open and characterized by innovative applications. Juniper Networks® Junos® Software Development Kit (SDK) is the product that developers use to build theseJuniper Networks Junos SDK enables applications to run at the network device layer on the Junos OS platform. Applicationsdevelopers to innovate on top of running on the Junos operating system enhance the network at its most intimate layerJuniper systems and the Junos as they run in the control and services planes directly on the systems that connect theoperating system by building, deploying, network. The APIs exposed in the Junos SDK allow applications to use the network and itsand validating innovative network traffic in new and dynamic ways.applications. The Junos SDK challengesthe paradigm of the industry’s existing The common set of tools and APIs for rapid development across all Juniper systems isnetwork offerings based on closed inherited from the “one Junos” story—a single network operating system unified acrossand nonextensible software powering the Juniper routing, switching, and security portfolio.

Because a Routingthrough new and optimized services and Engine is always present in any device, Routing Engine SDK-based applications are alwaysby offering new business opportunities. deployable without the addition of any extra hardware or software. Applications can programmatically manipulate the platform software in dynamic ways in the form of daemons and other ephemeral processes that run as utilities. User interface extensions usually accompany such software so that applications can be configured and administered in the same ways as the Junos platform applications. 1

Junos SDK plug-in for the Eclipse A plug-in for the Eclipse development environment greatly facilitates the coding through debugging development environment workflows. Install wizard The installer tool sets up and helps to maintain the Junos SDK APIs and tools so that developers can get productive as quickly as possible without cumbersome administration. Application build and simulation tools Tools to build, package, sign, test, and debug applications for Junos OS are included, as well as tools to simulate the Junos OS user interface with newly developed extensions. Virtual build environment A virtual machine image runs a build environment and the user interface testing tools. Learning and support The Junos SDK offers comprehensive topical and reference documentation. Online and live training as well as a development support staff are also available to developers.Program information About Juniper networksFor more information on the Junos SDK, please visit Juniper Networks is in the business of network innovation. devices to data centers, from consumers to cloud providers, Juniper Networks delivers the software, silicon and systems that transform the experience and economics of networking.
