MX104 Universal Routing Platform Overview

The Juniper Networks MX104 Universal Routing Platform is optimized for aggregating mobile, enterprise WAN, business, and residential access services. The MX104 router is designed for high-density access and pre-aggregation and is environmentally hardened to allow outside deployments in cabinets and remote terminals. The router is a high-performance router functioning as a universal aggregation platform for mobile broadband and metro Ethernet applications. It also acts as a universal edge platform supporting all types of private WAN, data center interconnect, Internet edge, business edge, and residential edge services.

The router is powered by the Junos Trio chipset and runs the Junos® operating system (Junos OS) for high-performance routing and switching. For a list of related Junos OS documentation, see https://www.juniper.net/documentation/software/junos/.

Benefits of MX104 Router

  • System Capacity—MX104 provides 80 Gbps of throughput. MX104 has four Modular Interface Card (MIC) slots and supports redundant fixed 10-Gigabit Ethernet interfaces for flexible network connectivity.

  • The Programmable Chipset—The chipset implemented in the MX Series routers has a programmable forwarding data structure that allows fast microcode changes in the hardware itself, and a programmable lookup engine that allows inline service processing. the chip’s programmable QoS engine supports coarse and fine-grained queuing to address the requirements of core, edge, and aggregation use cases.

  • Always-on infrastructure base—MX Series routers ensure network and service availability with a broad set of multilayered physical, logical, and protocol-level resiliency aspects. Junos OS Virtual Chassis technology on MX Series routers supports chassis-level redundancy and enables you to manage two routers as a single element. Multichassis link aggregation group (MC-LAG) implementation supports stateful chassis, card, and port redundancy.

  • Application-Aware Networking—On MX Series routers you can use deep packet inspection to detect applications, and by using the user-defined policies, you can determine traffic treatment for each application. This feature enables highly customized and differentiated services at scale.

  • Junos Continuity and Unified In-Service Software Upgrade (Unified ISSU)—With the Junos continuity plug-in package, you can perform a smooth upgrade when new hardware is installed in your MX Series router.

    Unified in-service software upgrade (unified ISSU) enables software upgrades and changes without disrupting network traffic.

  • Junos Telemetry Interface—Using the Junos telemetry interface data, you can stream component-level data to monitor, analyze, and enhance the performance of the network. Analytics derived from this streaming telemetry can identify current and trending congestion, resource utilization, traffic volume, and buffer occupancy.

  • Integrated Hardware-Based Timing— You do not need to use external clocks because MX Series routers support highly scalable and reliable hardware-based timing, 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 a high level of frequency (10 ppb) and phase (<1.5 uS) accuracy.

System Overview

The chassis is a rigid sheet metal structure that houses all the other router components (see Figure 1 and Figure 2). The hardware system provides resiliency and redundancy, including power supplies and Routing Engines. The chassis also has four built-in 10-Gigabit Ethernet SFP+ ports and four slots that accept Modular Interface Cards (MICs). For a list of the supported MICs, see the MX Series Interface Module Reference.

The router is environmentally hardened and is 3.5 rack units (U; that is, 6.125 in., or 15.55 cm) tall. Several routers can be stacked in a single floor-to-ceiling rack, for increased port density per unit of floor space. The chassis is installed in standard 11.81 in. (30 cm)-deep (or larger) enclosed cabinets, 19-in. equipment racks, or telco open-frame racks.
