MX5, MX10, MX40, and MX80 Router Overview
The Juniper Networks MX5, MX10, MX40, and MX80 Universal Routing Platforms are Ethernet-optimized edge routers that provide both switching and carrier-class Ethernet routing. The MX5, MX10, MX40, and MX80 routers run Junos operating system (Junos OS), enabling a wide range of business and residential applications and services, including high-speed transport and virtual private network (VPN) services, next-generation broadband multiplay services, and high-volume Internet data center internetworking. Each router provides full duplex, high-density Ethernet interfaces and high- capacity switching throughput and uses the Junos Trio chipset for increased scalability of L2/L3 packet forwarding, buffering, and queuing.
Benefits of the MX5, MX10, MX40, and MX80 Router
System Capacity—The MX80, MX40, MX10, and MX5 routers are software upgradeable from 20 Gbps to 80 Gbps. These platforms have up to four Modular Interface Card (MIC) slots and two fixed 10-Gigabit Ethernet interfaces for connecting to the network.
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.
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.
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.
MX5, MX10, MX40, and MX80 Hardware Overview
The routers each contain a built-in Routing Engine and one Packet Forwarding Engine. The Packet Forwarding Engine has two “pseudo” Flexible PIC Concentrators (FPC 0 and FPC1). Because there is no switching fabric, the single Packet Forwarding Engine takes care of both ingress and egress packet forwarding.
The routers are compact and two rack units (U) tall. Several routers can be stacked in a single floor-to-ceiling rack for increased port density per unit of floor space.
For scalable configuration options you can install a variety of Modular Interface Cards (MICs) in the two front slots of the router, and the optional Multiservices MIC can be installed in the rear slot. Software licenses allow you to upgrade from one router to another without a hardware upgrade. The ports are restricted based on the router’s associated license as follows:
MX5 router: Allows usage of the MIC slot labeled
1/MIC 0, which comes prepopulated with the Gigabit Ethernet MIC with SFP.
MX10 router: Allows usage of the MIC slot labeled
1/MIC 0, which comes prepopulated with the Gigabit Ethernet MIC with SFP and the second MIC slot labeled
MX40 router: Allows usage of the front MIC slots and ports
1of the built-in 10-Gigabit Ethernet MIC (labeled
MX80 router: Allows usage of all MIC slots (front and back) and all four ports of the built-in 10-Gigabit Ethernet MIC (labeled
A fixed version of the MX80 router (model number: MX80-48T) has 48 fixed 10/100/1000Base-T RJ45 ports in place of the MIC slots.
