The MX Series portfolioenterprise applications.offers a broad range of physical and virtual platforms that deliver routing capacity from1 Gbps through 80 Tbps. The MX Series portfolio includes the vMX virtual router; highlycompact routers such as the MX5, MX10, MX40, and MX80; an aggregation optimizedrouter, the MX104; modular edge routers including the MX240, MX480, and MX960; andultra-high capacity edge and converged edge/core platforms such as the MX2010 andMX2020. This datasheet specifically addresses the Juniper Networks MX240, MX480, andMX960 3D Universal Edge Routers. The MX240 offers high-interface density and performance in a space-efficient packagethat is practical for enterprise WAN, data center, and campus deployments as well asseveral service provider applications in small and medium points of presence (POPs). The MX480 provides a dense, highly redundant platform primarily targeted for mediumto large enterprise campuses and data centers, and service provider edge applicationsin medium and large PoPs. The MX960 is a high-density, high-capacity platform designed for the service provideredge and data center cores.Your ideas. Connected. 1

These advancedcapabilities allow you to flexibly mix and match interfaces tocreate service-specific and “pay-as-you-grow” configurations.The MPC houses the PFEs to deliver comprehensive Layer3 routing (IPv4 and IPv6), MPLS, and Layer 2 switching andadvanced Hierarchical quality-of-service (HQoS).For more details on MPCs, please visit www.juniper.net/us/en/Switch Control Board (SCB)local/pdf/datasheets/1000294-en.pdf.The SCB powers on and powers off cards, controls clocking,Dense Port Concentrator (DPC)resets, boots, monitors and controls system functions, includingfan speed, board power status, inline power distribution module(PDM) status and control, and the system front panel. Theswitch fabric is integrated into the SCB, providing a non-blockingarchitecture that connects to all within the chassis, and theRouting Engine installs directly into the SCB. Three SCBs areavailable for the MX960, MX480, and MX240 routers—the SCB,the SCBE, and the SCBE2.DPCs provide multiple physical interfaces and PFEs on a singleboard that installs in a slot in the MX Series routers. A DPCreceives incoming packets from the network and sends outgoingpackets to the network. The PFEs on a DPC are equippedwith purpose-built ASICs that perform packet processingand forwarding. Each PFE consists of one I-Chip for Layer 3processing and one Layer 2 network processor.For more details on the DPC, please visit www.juniper.net/us/en/Table 2: SCB lNumberDescriptionSwitch Fabric Capacity (Tbps)SCBE2MX-BBEnhancedMX SwitchControl Board(SCBE2)1.92SCBEMX-BBEnhancedSwitch ControlBoard (SCBE).962.725.12SCBMX960BBSwitch ControlBoard (SCB).481.442.64MX240MX4805.12MX9609.92Junos OSJunos OS is a single, modular OS with a single release cycle thatis supported across all Juniper Networks routers, switches, andsecurity devices in a unique approach that extends significantoperational and economic benefits. Junos OS streamlinesnetwork operations and improves the availability, performance,and security of all types of services supported by the MXRouting Engine (RE)The Routing Engine handles all routing protocol processes,the software processes that control the router’s interfaces, thechassis components, system management, and user accessto the router. These routing and software processes run on topof a kernel that interacts with the Packet Forwarding Engine(PFE). The Routing Engine also provides control plane functionsand runs Junos OS. Software processes that run on the RoutingEngine maintain the routing tables, manage the routing protocolsused on the router, control the router interfaces, control somechassis components, and provide the interface for systemmanagement and user access to the router. Routing Enginescommunicate with DPCs and MPCs via dedicated out-of-bandSeries 3D Universal Edge Routers, including L2/L3 VPNs, trafficsegmentation, low-latency multicast, and comprehensiveQoS features that accelerate the delivery of time-sensitiveapplications.Junos OS also offers advanced virtualized network services suchas Virtual Chassis technology, cloud-based CPE, and networkedge services such as network address translation (NAT) andcarrier-grade NAT (CGNAT), IPsec, flow monitoring, and statefulfirewall—allowing the seamless and operationally efficientintegration of these advanced service capabilities directly onthe MX Series. Unlike other network operating systems that arefragmented into many different release images joined under acommon “brand,” our unified approach to OS development anddeployment reduces the cost, complexity, and time to implementand maintain network infrastructure.management channels, providing a clear distinction between thecontrol and forwarding planes.2
