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.
Service providers and cloud operators are making infrastructure investments today that pave the way for digital cohesion, enhancing the user experience while supporting emerging market trends with mobility, Internet of Things (IoT), and the continued growth of cloud networking. At the same time, these providers and operators are building out their networks to ensure performance, efficiency, and agility at cloud-era scale. To achieve these business goals and succeed in their respective hyper-competitive markets, service providers and cloud operators need software-centric edge solutions that satisfy current demand while offering investment protecting evolution to emerging technologies and growth.
Realizing this edge vision requires service-oriented edge platforms that offer the density and throughput needed to accommodate anticipated traffic growth driven by ubiquitous video content, media-rich business services, and emerging technology trends like IoT, connected vehicles, and smart cities.
Juniper Networks® MX304 Universal Routing Platform1 is a cloud-era platform that cost effectively addresses the evolutionary edge and metro Ethernet needs of service providers, mobile operators, web-scale operators, and multiple-service operators (MSOs). Offering ultra-high-density 10GbE, 25GbE, 40GbE, 50GbE, 100GbE, and 400GbE connectivity in a space- and power-optimized package, the MX304 delivers 4.8 Tbps of throughput in just two rack units (RU), providing unmatched edge router density and performance while consuming just 0.3 W/Gb of throughput.
Powered by the same programmable Junos® Trio chipset and Junos operating system that powers the entire MX Series Universal Routing Platforms portfolio, the MX304 leverages nearly two decades of Juniper R&D investments and innovations that have transformed the economics of networking. Key features include a comprehensive suite of advanced automation and telemetry capabilities that serve as the foundation for future self-driving networks, as well as line-rate 400GbE Media Access Control Security (MACsec) encryption and integrated advanced timing. By combining service centricity, high throughput, and density with space and power efficiency, the MX304 helps network operators overcome the challenges of a hyper-connected world and profitably deliver the widest variety of services and applications.
Architecture and Key Components
The MX304 Universal Routing Platform features the following components.
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.
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.

Features and Benefits
Industry-Leading Port Density
The MX304 is a full-featured single-chassis edge router that offers high port density in a compact form factor (see Table 1).
|Per MIC Port Density
|Per Chassis Port Density
Unmatched Network Availability
A comprehensive set of hardware and software features enables the MX304 to deliver the highest levels of network availability for a 2 RU edge router. The MX304 supports 1+1 control plane redundancy and 1+1 power supply module redundancy. From a software standpoint, Junos OS runs each program independently in its own protected memory space, ensuring that individual processes do not interfere with one another.
Excellent Power Design and Efficiency
The MX304 offers excellent, industry-leading power design and efficiency, consuming just 0.3 W/Gb to ensure proper chassis operation under all conditions—critical when considering next-generation network elements. The MX304 monitors power and temperature for each chassis component, shutting down interfaces and components when power or temperature thresholds are exceeded.
Junos Telemetry Interface
The programmable Junos Trio 6 chipset provides the power to monitor and collect data at the component level. The chipset uses the Junos Telemetry Interface to stream this data in a scalable manner to monitoring, analytics, and performance management applications, as well as to Path Computation Elements (PCEs) such as Juniper Networks Paragon Pathfinder. The derived telemetry information identifies current and trending congestion, resource utilization, traffic volume, latency, and delay, helping service providers detect issues and make informed decisions about network design, optimization, and investments.
MX Series routers support highly scalable and reliable hardware-based timing that meets the strictest LTE requirements, including Synchronous Ethernet for frequency and the Precision Time Protocol (PTP) for frequency and phase synchronization. Synchronous Ethernet and PTP can be combined in a “hybrid” mode to achieve the highest level of frequency (10 ppb) and phase accuracy (< 1.5 uS) required for LTE-Advanced, eliminating the need for external clocks. The MX304 also supports advanced timing standards such as G.8275.1.
Junos Automation Toolkit
The Junos Automation Toolkit, included in the Junos OS software, offers a suite of tools supported on all Juniper Networks switches, routers, and security devices. These tools leverage the native XML capabilities of Junos OS, including commit scripts, operations scripts, event policies and scripts, and macros that automate operational and configuration tasks. Automation saves time by performing repetitive operational and configuration tasks, speeding troubleshooting, and maximizing network uptime by warning operators of potential problems and automatically responding to system events.
Applications and Use Cases
The MX304 Universal Routing Platform delivers a powerful solution for the following use cases.
The MX304 offers the 10GbE, 25GbE, 40GbE, 50GbE, 100GbE, and 400GbE interfaces that large enterprises and service providers need, as well as a comprehensive VPN toolkit to support feature-rich, standards-based, and secure internetworking for innovative business services.
