Architecture and Key Components

Platform Components

Switch Fabric Board

Switch Fabric Boards (SFBs) create a highly scalable and resilient

“all-active” centralized switch fabric that delivers up to 4 Tbps of

full-duplex switching capacity to each MPC slot in an MX2000

router.

Control Board and Routing Engine

Dual redundant Control Board and Routing Engines (CB-REs) run

the 64-bit Junos OS and support routing protocol processing,

router interface control, and control plane functions such as chassis

component, 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 Port Concentrators

(MPCs) via dedicated high-bandwidth management channels,

providing a clean separation of the control and forwarding planes.

Power

The MX2000 power and thermal subsystems use advanced

technology to optimize power efficiency without sacrificing scale or

features. The power subsystem has a highly resilient architecture

for full power supply and power cable feed redundancy. MX2000

routers are available with -48 V DC or AC power (in Delta or Wye

3-phase configuration) along with HVDC and HVAC power,

allowing power to be added to the rack as needed.

Modular Port Concentrators

Modular Port Concentrators (MPCs) provide comprehensive

routing, switching, inline services, subscriber management, and

advanced hierarchical quality of service (HQoS) to address the

widest set of network and service applications. Some MPCs provide

network connectivity directly; others host Modular Interface Cards

(MICs) that allow users to mix-and-match interfaces.

The MPC11E, powered by the Trio 5 chipset, delivers 4 Tbps per

slot and provides near-infinite hardware programmability that

addresses future innovative protocols. Optimized for 100GbE

speeds and above, the MPC11E provides 400GbE-ready ports with

multi-rate QSFP56DD interfaces for seamless 100GbE to 400GbE

upgrades. The MPC11E offers industry-first support of native

MACsec with no impact on performance (throughput or latency).

The technology recalibrates network economics, keeping up with

increasing bandwidth demands while being backward-compatible

with all prior functionality.

The MPC6E, MPC8E and MPC9E are specifically designed to take

advantage of the ultra-high fabric capacity of the MX2000 line.

Powered by the programmable Junos Trio chipset, these MPCs

offer extremely high 10GbE, 40GbE and 100GbE port densities

with line-rate performance. These MPCs also stream telemetry for

performance management and billing purposes.

An adapter card4 allows the use of the MPC1 through MPC5, as

well as the MPC7E, in the MX2000 line, protecting existing MPC

investments. The MX2000 platforms provide per-port line-rate

MACsec encryption and decryption at 10GbE, 40GbE, and 100GbE

speeds with no fragmentation impact, providing an inexpensive and

simple mechanism for securing L2 communications. The MX2K-

MPC11E line card delivers 4 Tbps per slot throughput, and MACsec

can be selectively enabled on each interface at 10GbE, 40GbE, and

100GbE speeds. The MX2K-MPC9E and MX2K-MPC8E line cards

with the MIC-MACSEC-MRATE pluggable MIC can selectively

provide MACsec encryption on 10GbE, 40GbE, and 100GbE

speeds. The MPC7E-10G line card offers another option for

achieving native 10GbE density with MACsec capability on the

MX2000 line of routers.

MS-MPCs, which also require an adapter card for use in the

MX2000 line, provide dedicated processing for Network Edge

Services (CGN, IPsec, stateful firewall, deep packet inspection [DPI],

monitoring, and other compute-intensive services) and efficiently

integrate these services directly on the MX2000 platforms at scale

and without impacting forwarding performance. MS-MPCs also

reduce dependence on appliances and the layers of complexity they

add to the operations environment.

Junos Operating System

Junos is a reliable, high-performance, modular network operating

system that is supported across all of Juniper Networks physical

and virtual routing, switching, and security platforms, reducing the

cost, complexity, and resources required to implement and maintain

the network. With secure programming interfaces, the Juniper

Extension Toolkit and versatile scripting support, and integration

with popular orchestration frameworks, Junos OS offers flexible

options for continuous delivery and DevOps style management that

helps service providers of all types unlock more value from the

network.

To provide optimal air flow and maximize interface density, MX2000 line MPC slots are wider than the MPC slots on

the MX240, MX480, and MX960. An Adapter Card enables MPC1 through MPC5, MPC7 and MSMPC use in the

MX2000 line; these cards require no configuration and are visible in the system inventory from the CLI.
