Juniper Networks MX10008
Performance and versatility, powered by infinite programmable silicon.

Architecture and Key Components:

The MX10000 line of modular routers features a number of architectural elements. Dual redundant Routing Engines (REs) run Junos OS, where they manage all routing protocol processes, router interface control, and control plane functions such as chassis components, system management, and user access to the router. These processes run on top of a kernel that interacts with the PFE on the line cards via dedicated high-bandwidth management channels, providing a clean separation of the control and forwarding planes.

The MX10000 modular line cards currently support 10GbE, 40GbE, and 100GbE interfaces, and are designed to support 400GbE interfaces in the future. The line cards are oriented horizontally in the front of the chassis, connecting directly to the vertical switch fabric cards in the rear of the chassis via orthogonal interconnects without requiring a midplane. This provides unparalleled investment protection by ensuring a smooth upgrade path to higher speed switch fabric cards as they become available. The midplane-less design also improves airflow with a front-to-back design.

To maintain uninterrupted operation, modular fan trays cool the line cards and REs with redundant, variable-speed fans. In addition, all MX10000 modular components are hot-swappable, and all central functions are available in redundant configurations, providing high operational availability by allowing continuous system operation during maintenance or repairs. The chassis’ universal design also allows them to be used independently for core, edge, or switching configurations.

Line Modular Hardware Components

Line Cards

The line cards for the MX10000 line of modular platforms are based on highly scalable, custom Juniper Trio silicon, making it the industry’s leading router for data center edge, core, peering, and aggregation applications. Each slot on the MX10008 and MX10016 supports 2.4 Tbps (4.8 Tbps half-duplex), while the line cards support multi-rate 10GbE, 40GbE, and 100GbE interfaces.

The modular design of the MX10008 and MX10016 routers provides investment protection by allowing future upgrades. The PFEs offer 400 Gbps of WAN and fabric bandwidth. To achieve 2.4 Tbps forwarding performance, a total of six PFEs are implemented on each interface card. The PFEs provide ingress queuing with loopback stream optimization to avoid reading and writing packet tails when packets are sent to and received back from a loopback stream. The line cards also provide Operation, Administration, and Maintenance (OAM) support with per-port Ethernet OAM counters, as well as packet memory, which uses Hybrid Memory Cube DRAM technology to reduce power usage, increase speed, and improve system density.

Processor

The MX10008 and MX10016 RE features a 10-core 2.2 GHz Intel processor with 64 GB memory and 2x200 GB solid-state drive (SSD) storage.

Power

The MX10008 contains six power supply slots while the MX10016 contains ten power supply slots to provide complete flexibility for provisioning and redundancy. Each power supply has its own internal fan for cooling. The MX10000 modular line supports both AC and DC power supplies; however, AC and DC supplies cannot be mixed in the same chassis.

The first generation of AC power supplies on the MX10008 and MX10016 accept 200 to 240 volts alternating current (VAC) input, delivering 2700 watts of power to the chassis. The DC power supplies accept -40 to -72 volts direct current (VDC) input, delivering 2500 watts of power to the chassis. Each AC and DC power supply has two inputs for feed redundancy.

The second generation of AC/DC power supplies on the MX10008 and MX10016 delivers up to 5500 W per unit to the chassis, enabling dense 400GbE with optional lower-power settings.

Cooling

The MX10000 line of modular chassis supports front-to-back cooling with air drawn in through perforations on the REs and the line cards in the front of the platform, while hot air exits through the rear of the chassis. The modular fan trays are accessible from the rear of the chassis.

Chassis Management

The MX10000 modular line delivers powerful Junos OS chassis management that allows environmental monitoring and field-replaceable unit (FRU) control. Chassis management provides a faster primary switchover, enhanced power budgeting with modular power management, reduced power consumption for partially populated systems, granular control over FRU power-on, single zone cooling with better fan speed control for reduced noise, and CPU leveling during monitoring intervals.

Simplified Management

The MX10000 modular line simplifies management based on the elegance and simplicity of Junos OS. Management applications can receive streaming telemetry data to provide robust protocol analytics for an SDN environment. Junos OS also supports OpenConfig, which today is a YANG-based data model that supports a variety of operator use cases.

Features and Benefits:

Feature	Feature Description	Benefits
System capacity	The MX10008 scales to 19.2 Tbps (38.4 Tbps half-duplex) in a single chassis, breaking out into 768 10GbE, 192 40GbE, and 192 100GbE interfaces. The MX10016 scales to 38.4 Tbps (76.8 Tbps half-duplex) in a single chassis, breaking out into 1536 10GbE, 384 40GbE, and 384 100GbE interfaces.	The MX10000 line gives cloud and service providers the performance and scalability needed to outpace increased traffic demands.
Packet performance	The innovative and groundbreaking Juniper Trio silicon empowers the MX Series routers with unparalleled packet processing for both full IP and MPLS functionality, leveraging revolutionary 3D memory architecture.	Exceptional packet processing capabilities alleviate the challenge of scaling the network as traffic continues to increase, while optimizing IP/MPLS transit functionality around superior performance and elegant deployability.
Full-scale IP and MPLS routing	The MX10000 modular line features a rich set of IP/MPLS services, low latency, and wire-rate forwarding at scale, while providing the reliability needed to meet strict service-level agreements (SLAs).	Distributed peering scale of 7 million forwarding information base (FIB) and 80 million routing information base (RIB) (also known as forwarding and routing tables, respectively) delivers the performance required to match expanding traffic demands.
Source Packet Routing in Networking (SPRING)	Junos OS supports SPRING, which provides the ability for a trusted source node to specify a forwarding path, other than the normal shortest path, that a particular packet will traverse.	SPRING support provides additional flexibility per packet source. It also adds features such as network path and node protection to support fast reroute (FRR) mechanisms, enhanced network programmability, OAM functionality, simplified network signaling, load balancing, and traffic engineering functions.
High availability hardware	The MX10000 modular line is designed with full hardware redundancy for cooling, power supply, REs, and switch fabric, as applicable.	High availability (HA) is a critical requirement for service providers to maintain an always-on infrastructure to meet stringent SLAs.
High availability software	The MX10000 modular line features a resilient operating system that supports HA features such as graceful RE switchover (GRES), nonstop active routing (NSR), and unified in-service software upgrade (unified ISSU) for high availability. The MX Series also supports game-changing 50 ms redundancy switchover under load.	Junos OS supports HA features that allow software upgrades and changes without disrupting network traffic.
