    Virtual Services Engine and JunosV App Engine Overview

    Virtual Services Engines (VSEs) are devices on which the JunosV App Engine is deployed. JunosV App Engine is a virtualization platform that hosts network services and applications, which run inside guest operating systems within virtual machines, on the VSE devices.

    Each application is built along with its native operating system (OS) into a virtual machine image and then packaged into a Junos-installable package using JunosV App Engine tools. JunosV App Engine enables language-independent and OS-independent integration of third-party and Juniper Networks applications with Junos-based devices. For example, Linux applications can still run on Linux and integrate with devices running Junos OS. JunosV App Engine provides a simpler, cheaper and faster mechanism to integrate with the Junos platform, greatly reducing, and in some cases eliminating, the effort needed to integrate into the Junos environment.

    The supported guest operating system is currently the Linux operating system, and the hardware is a tethered device attached to the router on either the router media interface (for example, ge-1/1/0) or a management LAN network (for example, fxp0).

    VSE devices and JunosV App Engine together enable creation of multiple instances of the same OS, which offers a scalable software architecture, and provide interfaces for non-Junos applications to integrate into the Junos management system, control plane, and data plane.
