Overview:
As cloud builders, telecom service providers, and cable operators seek to improve customized digital experiences for their customers, they must concurrently address everincreasing bandwidth demands on their network. Meeting these objectives requires a dynamic, service-oriented edge routing platform that cost-effectively scales to meet both current demand and long-term forecasts.
The SDN-ready MX2000 line of 3D Universal Edge Routers are true cloud-grade networking platforms that help network operators of all types achieve their business goals by combining unparalleled performance, reliability, and security with a programmable, software-centric design at massive scale including line-rate encryption capabilities. Simply put, the MX2000 routers offer the system capacity, linerate port density, and serviceoriented design that network operators need to thrive today and in the future.
Product Description
Increasingly sophisticated technology users are seeking highly responsive and customizable cloud-like online experiences and services that align with their unique needs and interests. At the same time, these users are creating more traffic that consume ever-increasing amounts of network bandwidth. For example, global e-commerce sales are growing at 20 percent annually; enterprises are increasingly moving infrastructure to the cloud1; every minute of every day, more than 300 hours of video are uploaded to YouTube2; and analysts expect 26 billion Internet of Things (IoT) devices to be in use by 2020—more than a tenfold increase from 20153.
As network operators strive to profitably meet these market demands, they are thwarted by traditional hardware-centric edge routers that lack programmability and scale, which limits their competitiveness, constrains their revenue and market share growth, and increases their CapEx, OpEx, and TCO. Now more than ever, service providers need agile, service-oriented edge routers that cost-effectively scale to create a Cloud-Grade Network that meets current demand and long-term forecasts.
Meeting these challenges head-on, Juniper Networks® MX2000 line of 3D Universal Edge Routers—consisting of the 80 Tbps-capable MX2020 and the 40 Tbps-capable MX2010 and MX2008—enables network operators to confidently build the best cloud-grade core and edge networks across residential, mobile, business, and cloud/hosting markets.
Significantly, the MX2000 platforms run the same Juniper Networks Junos® OS as the entire MX Series 3D router portfolio, ensuring complete feature consistency and a common operational and management framework. This consistency reduces the cost, risk, and complexity of network evolution, helping current MX Series customers rapidly qualify and deploy the MX2000 routers.
Due to increasing security threats and data privacy concerns, Juniper has also made linerate Layer 2 encryption standard across the majority of its products, including the MX2000 line, by integrating MACsec technology. Starting in Q1 2018, the MX2000 platforms ship with 40GbE and 100GbE MACsec enabled on the MACsec-capable MIC-MACSEC-MRATE pluggable MIC for the MPC8E and MPC9E line cards. The 10GbE MACsec capability has been available on the MPC7E-10G line card since 2016.

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 2 Tbps of fullduplex 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), and allow 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 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 also provide perport line-rate MACsec encryption and decryption at 10GbE, 40GbE, and 100GbE speeds with no fragmentation impact. This feature provides an inexpensive and simple mechanism to secure L2 communications. The MX2K-MPC9E line card with the MIC-MACSEC-MRATE pluggable MIC delivers 1.6 Tbps per slot throughput and can be selectively enabled on each interface at 10GbE, 40GbE, or 100GbE speeds. The MIC-MACSEC-MRATE is also compatible with the MX2K-MPC8E line card. The MPC7E10G 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.
4 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.

Unmatched Network Availability
The MX2000 line of 3D Universal Edge Routers offers a broad set of hardware and software features that together ensure nonstop network availability. The MX2000 line supports N+1 fabric redundancy, control plane redundancy, N+N power feed redundancy, and even N+1 power supply module redundancy. In addition, Virtual Chassis technology supports chassislevel redundancy while allowing users to manage two routers as a single element. Juniper’s link aggregation group (LAG) implementation also supports stateful card and port redundancy, as well as subscriber and session persistence.
From a software perspective, Junos OS runs each program independently in its own protected memory space, ensuring individual processes do not interfere with one another. Unified ISSU permits non-disruptive OS upgrades, while Junos Continuity allows new hardware to be added to an MX Series router with the addition of a simple plug-in package, which is installed fully in service without any interruption.

Embedded Element-Layer Analytics
The programmable Trio chipsets provide the power to monitor and collect data at the component level, and use the Junos Telemetry Interface to stream this data in a scalable manner into monitoring, analytics, and performance management applications (see Figure 1), and to Path Computation Elements such as Juniper Networks NorthStar Controller.
This information will help identify current and trending congestion, resource utilization, traffic volume, latency and delay, which network operators can use to detect issues, make informed decisions on network design, optimization and investment.
Integrated Network Edge Services
Hosting Network Edge Services directly on MX2000 routers— without impacting routing or forwarding performance—helps streamline operations and reduce TCO by consolidating and eliminating service-specific appliances as well as their operating systems and management systems.
Juniper’s Network Edge Services portfolio includes:
- Junos Subscriber Aware, which allows per-subscriber traffic steering, policy enforcement, and accounting
- Junos Application Aware, which allows L4-L7 traffic identification, policy-based traffic handling, and accounting
- Junos Address Aware, which conserves the IPv4 address pool, ensures IPv4/IPv6 coexistence, and aids in the transition to IPv6
- Junos Network Secure, which provides stateful firewall services for network protection and managed security
- Junos VPN Site Secure, which uses standard encryption modes to secure communications over access networks, and for added security over L3 VPNs
- Junos Traffic Vision, which provides the granular traffic visibility needed to improve network efficiency, increase security, and support operational tasks
- Junos Video Focus, which provides standards-based video monitoring and automatic issue mitigation to ensure highquality customer experiences
- Junos Web Aware, a powerful application that tracks HTTP requests and responses, and enables tag insertion and header enrichment
- Junos L4 Load Balancer, a hybrid traffic load balancer based on advanced Junos OS capabilities that increases network efficiency
Network Edge Services are optional and licensed individually; the MX2000 routers can host multiple services concurrently.
Outstanding Power Design and Efficiency
The MX2000 line sets the bar for edge router power design and efficiency, increasingly important considerations for CloudGrade Networks.
At the system level, power can be flexibly provisioned to meet site-specific environmental conditions, and less power can be provisioned in facilities that consistently operate at <25C, providing significant operational savings. Power consumption is also dynamically managed based on actual hardware configuration; additional power is only allocated when a MIC is installed versus pre-provisioning power for worst-case scenarios. Additionally, fan speed is dynamically governed by actual temperature monitoring; at ambient temperature, fans consume only 20 percent of their maximum power.
Juniper has also implemented power optimizations at the silicon level. “Clock gating” reduces dynamic power dissipation by disabling unused logic circuitry; unused memory is also dynamically placed in “sleep mode” to conserve power.
These optimizations, when coupled with Juniper’s most advanced MPCs and optics, enable the MX2000 line to achieve an incredible power-to-throughput efficiency ratio of .6W/GbE; this means the MX2020 consumes just six-tenths of a watt to forward 1GB of traffic.
Addresses Broadest Set of Service Provider Applications
Broadband Edge
The MX2000 line offers powerful Broadband Network Gateway (BNG) features that allow broadband services to be provisioned for today and tomorrow. The MX2000 line supports the highest subscriber density and the most sophisticated broadband edge features, including hierarchical quality of service (HQoS), support for Point-to-Point Protocol (PPP) subscriber termination, Dynamic Host Configuration Protocol (DHCP), IPv4/IPv6 local server, and relay proxy for subscriber migration to DHCP access models. Juniper’s BNG also supports hierarchical queuing, granular QoS, and dynamic multilayer service activation, RADIUS, and diameter support for backend server integration to facilitate authentication, policy control, and accounting, as well as support for flexible L2/L3 wholesale models.
Business Edge
The MX2000 line of routers includes a comprehensive VPN toolkit to support feature-rich, standards-based, secure internetworking for innovative business services. In addition to basic L2/L3 VPN and VPLS support, the MX2000 line offers enhanced VPN services such as QoS-prioritized VPN traffic for voice and video, VPN-aware multicast and firewall services that leverage technologies such as LDP-BGP / VPLS internetworking, point-to-multipoint label-switched paths (P2MP LSPs), BGPbased multicast L3VPN, L2 VPN internetworking to connect dissimilar L2 access networks, MPLS plug-and-play, and IPsec/ generic routing encapsulation (GRE) VPNs.
IP Core
The feature-rich MX2000 line of routers is ideal for core, consolidated edge/core, and peering applications. Key features include high system capacity, high FIB scale, high-density 100GbE interfaces as well as DWDM and IP/optical support, inline video monitoring, and node virtualization. Additionally, Junos OS supports Source Packet Routing in Networking (SPRING, RFC 7855), which enables a trusted source node to specify a forwarding route other than the normal shortest path that a particular packet will traverse.
Metro Ethernet
The MX2000 line of routers provides outstanding support for metro and aggregation networks by offering a full suite of routing and switching features, allowing network operators to choose a deployment model that fits their business and technical needs. The MX2000 line can be deployed as IP/IP VPN edge routers, Ethernet VPN (E-VPN) and VPLS provider edge routers (VPLS– PE), MPLS label-switching routers (LSR), and as Layer 2 Ethernet switches or Layer 3 IP routers.
Universal SDN Gateway
The MX2000 routers are ideal universal SDN gateways, interconnecting virtual and physical networks and virtual networks operating with different technologies. Key enabling features include support for Multiprotocol BGP (MBGP), dynamic tunnels using MPLS-over-GRE or VXLAN encapsulation, virtual routing and forwarding (VRF) tables or E-VPNs, and Netconf, as well as mechanisms to send traffic between VRF and global routing tables based on configuration and policy.
Service Control Gateway
The MX2000 line provides an excellent foundation for the Service Control Gateway, an advanced solution that considers network state, application type, subscriber privilege, and operator policy to deliver networked services. Leveraging Junos Application Aware, which uses deep-packet inspection techniques to identify and classify traffic on a per application basis, and Junos Subscriber Aware, which associates traffic flows with the subscriber that generated them, the Service Control Gateway supports differentiated service creation and delivery, and when used with Contrail Cloud Platform, can create and dynamically direct traffic into complex service chains.
