The Juniper Networks® ACX7024 and ACX7024X routers with Junos® OS Evolved version 24.4R2 is a network switch composed of hardware and firmware. The firmware is named Junos® OS Evolved which is the single purpose operating system that operates the management functions of all the Juniper Networks® routers.

The software is Junos® OS Evolved, which is the Juniper Linux-based operating system for network devices. It implements a flexible Software Defined Networking (SDN) allowing the tailoring of the software to several applications. Junos® OS Evolved is a horizontal software layer that decouples the application processes from the hardware on which the processes run. Effectively, this decoupling creates a general-purpose software infrastructure spanning all different computing resources on the system. Application processes (protocols, services, and so on) run on top of this infrastructure and communicate with each other by publishing and consuming (that is, subscribing to) the state. Junos® OS Evolved implements the routing, filtering, management, and platform functions.
