MX301 Overview

Meet the MX301

The Juniper Networks® MX301 Universal Routing Platform is a next-generation edge router engineered to deliver robust networking capabilities across a wide range of network deployment scenarios. The router provides flexible connectivity options with 26 WAN ports that offer port configurations from native 1/10 Gigabit Ethernet (GbE) up to 400GbE. The MX301 can deliver a maximum throughput of 1.6 terabit per second (Tbps) and has a compact 1-U fixed form factor. The MX301 is a power efficient router with usage as low as 0.3 watt (W) per Gb. The MX301 router runs on Junos OS.

The MX301 is ideal for high-density, high-throughput networking deployments in enterprise, cloud, service provider edge, and AI edge clustering use cases.

Where Can You Use the MX301?

Here are some possible use cases for the MX301:

Edge and core deployments—The MX301 has a 1-U compact form factor with interfaces configurable from 1GbE to 400GbE that supports up to 1.6 Tbps of throughput. This makes the MX301 ideal for enterprises to connect to service providers, and public or private cloud networks. The device can also be used for large branch offices and core deployments.
Distributed deployments—The MX301 can handle large subscriber sessions with capabilities to scale to the demands of modern broadband networks. The compact form factor, low power requirements, and integrated service functions make the MX301 ideal for distributed deployments on a broadband service provider's network.
Secure VPN router—With support for inline MACsec, IPSec encryption, and advanced VPN services, the MX301 can strengthen network integrity and deliver robust security for modern distributed networks.
Edge aggregation for AI—The MX301 is optimized to provide distributed AI inference, low-latency service, automation, and real-time analytics. The router uses inline MACsec, IPsec, and PTP to secure and manage autonomous AI traffic.
