Juniper Networks MX Series Universal Routing Platforms provide world-class technology and innovative architectures that enable service providers, cloud providers, and large enterprises to quickly react to changing market conditions in the cloud era, accelerating service delivery.
The MX304, an integral part of this family, offers massive scale and efficiency for space- and power-constrained environments. By redefining per-rack-unit economics, the MX304 helps customers do more with less while simplifying network design, reducing OpEx, and enabling profitable delivery of business, residential, mobile, cable, data center, and cloud services—all while seamlessly supporting traditional and emerging network architectures.
— Routing Engine
Dual redundant Routing Engines (REs) on the MX304 run Junos OS, where they manage all routing protocol processes, router interface control, and control plane functions such as chassis operations, system management, and user access to the router. These processes run on top of a kernel that interacts with the Packet Forwarding Engine (PFE) on Modular Interface Cards (MICs) via dedicated high-bandwidth management channels, providing a clean separation between the control and forwarding planes.
— Modular Interface Cards
Powered by the sixth-generation programmable Trio chipset, the MX304 offers unprecedented bandwidth in a dense form factor with MICs providing broad routing, switching, inline services, subscriber management, hierarchical quality of service (HQoS), and a host of other features. The MICs allow users to mix-and-match 10GbE, 25GbE, 40GbE, 50GbE, 100GbE, and 400GbE interfaces to flexibly and efficiently address their unique connectivity requirements.
— Power
The MX304 power and thermal subsystems use advanced technology to optimize power efficiency without sacrificing scale or features. The power subsystem is highly resilient, allowing full power supply and power cable feed redundancy, resulting in industry-leading power consumption efficiency.
— Junos Operating System
Junos OS is a reliable, high-performance, modular network operating system that is supported across all of Juniper’s physical and virtual routing, switching, and security platforms, reducing the cost, complexity, and resources required to implement and maintain a Juniper-based network. With secure programming interfaces, the Juniper Extension Toolkit (JET), versatile scripting support, and integration with popular orchestration frameworks, Junos OS offers flexible options for continuous delivery and DevOps-style management, helping service providers unlock more value from the network.
