Juniper MX-Series is a series of Ethernet Services routers designed and manufactured by Juniper Networks. These are a line of Ethernet-optimized multilayer packet processing devices designed for aggregation at the service-provider edge. These routers run on Juniper's network operating system, JUNOS. The MX960 platform is one of the industry's largest-capacity Carrier Ethernet platform, with up to 2.6 terabits per second (Tbit/s) of switching and routing capacity. In October 2009, MX-series was updated with new fabric and 120 Gbit/s per slot linecards based on "Trio" chipset. Second-generation MX series routers are known as MX 3D.
Models and Platforms
MX 5 3D
Same hardware as the MX 80 3D, but no 10GbE Ports and second MIC slot is not usable. Software license upgrade available.
MX 10 3D
Same hardware as the MX 80 3D, but no 10GbE Ports are usable. Software license upgrade available.
MX 40 3D
Same hardware as the MX 80 3D, but only 2x10GbE Ports are usable. Software license upgrade available.
MX 80 3D
The MX80 3D Ethernet Services router is the smallest member of MX family, featuring small form factor and one Modular Port Concentrator (MPC) with 80 Gbit/s capacity. Features four built in 10GE ports and two MIC slots.
MX240, MX240 3D
The Juniper MX240 Ethernet Services Router has a performance of 200+ Gbit/s throughput, scalability, and reliability in a space-efficient package.
MX480, MX 480 3D
The MX480 Ethernet Services Router is mainly used for dense dedicated access aggregation and provider edge services in medium-size and large Points of Presence (POPs).
MX960, MX960 3D
The Juniper MX960 Router is a high-density Layer 2 and Layer 3 Ethernet platform for several service provider Ethernet edge scenarios. The MX960 provides a range of Ethernet services, including VPLS services for multi-point connectivity. The MX960 is 14-slot router with 480 Gbit/s throughput in performance. A 40-port Gigabit Ethernet “dense port concentrator” (DPC) and a four-port 10G Ethernet DPC were the initial line card modules. With Trio-based 16x10GE linecards reaching the full-duplex 120 Gbit/s capacity. Each group of 4 10GE port on the Trio-based 16x10GE linecards has 40 Gbit/s forwarding capacity, but only 30 Gbit/s can be sent via the switch fabric toward other linecards (or other port groups of the same linecard).
The MX2010 and MX2020 are high capacity universal edge routers with 10 and 20 slots respectively, allocating 2 Tbit/s bandwidth per slot.
The MX Series is a family of high-performance Ethernet Services Routers with powerful switching features and are designed for high-performance service providers and enterprises. The MX Series has advanced MPLS, Multicast, Quality of Service, low latency and security capabilities. It provides flexibility and reliability to support advanced applications and services, including high-speed transport and VPN services, next-generation broadband multiplay services and high-volume Internet data center internetworking.
MX960 router include a switch control board (SCB), a routing engine and a Flexible physical interface card (PIC) Concentrator (MX-FPC). The SCB provides the switch fabric and control board functions, and acts as a carrier for the routing engine. The routing engine is similar to the routing engine for Juniper’s T-series and M-Series routers. The DPC is a single-wide interface card that supports a maximum of four 10 Gbit/s packet forwarding engines. The Dense Port Concentrators (DPCs) provide multiple physical interfaces and Packet Forwarding Engines (PFE) on a single board that installs in a slot in the MX Series routers.
The 14 open slots on the MX960 router holds 12 line cards and two SCBs in a non-redundant configuration or three SCBs and 11 line cards in a redundant configuration. When using MPC-3D, the last configuration is mandatory to reach 120 Gbit/s per linecard, and it is not redundant.
Two routing engines with a 1.3 GHz/1,331MB version and a 2 GHz/2,048MB options are available.
The MX960 supports up to 16,000 VLANs per packet-forwarding engine. On a per-box basis, the MX960 supports 16,000 MPLS Label Switched Path head-ends, 27 million IPv4 and IPv6 routing-information base entries, 1 million IPv4 and IPv6 forwarding-information base entries; 25,000 Virtual Private LAN Services (VPLS) labels; 500 Open Shortest Path First (OSPF) sessions, 500 Intermediate-System-to-Intermediate-System (IS-IS) adjacencies, and 100 Label Distribution Protocol (LDP) sessions and 4,000 Border Gateway Protocol sessions.
As of 2013, MX-Series and T4000 are the only Juniper product that supports inline-jflow (IPFIX), a high performance variant of jflow (Netflow), but on MX-Series it can only be activated on MPC 3D linecards and requires a specific license.
