•
Application-Aware Networking —On MX Series routers you can use deep packet
inspection to detect applications, and by using the user-defined policies, you can
determine traffic treatment for each application. This feature enables highly customized
and differentiated services at scale.
•
Programmable Chipset —The chipset implemented in the MX Series routers has a
programmable forwarding data structure that allows fast microcode changes in the
hardware itself, and a programmable lookup engine that allows inline service processing.
the chip’s programmable QoS engine supports coarse and fine-grained queuing to
address the requirements of core, edge, and aggregation use cases.
• Junos Continuity and Unified In-Service Software Upgrade (Unified ISSU) —With the
Junos continuity plug-in package, you can perform a smooth upgrade when new
hardware is installed in your MX Series router.
Unified in-service software upgrade (unified ISSU) enables software upgrades and
changes without disrupting network traffic.
• Junos Telemetry Interface —Using the Junos telemetry interface data, you can stream
component-level data to monitor, analyze, and enhance the performance of the
network. Analytics derived from this streaming telemetry can identify current and
trending congestion, resource utilization, traffic volume, and buffer occupancy.
• Integrated Hardware-Based Timing —You do not need to use external clocks because
MX Series routers support highly scalable and reliable hardware-based timing, including
Synchronous Ethernet for frequency, and the Precision Time Protocol (PTP) for
frequency and phase synchronization. Synchronous Ethernet and PTP can be combined
in a hybrid mode to achieve a high level of frequency (10 ppb) and phase (<1.5 uS)
accuracy.
MX480 Hardware Overview
The MX480 chassis provides redundancy and resiliency. The hardware system is fully
redundant, including power supplies, Routing Engines, and Switch Control Boards (SCBs).
The MX480 router is eight rack units (U) tall. Five routers can be stacked in a single
floor-to-ceiling rack, for increased port density per unit of floor space. The router provides
eight slots that can be populated with up to six Dense Port Concentrators (DPCs) or
Modular Port Concentrators (MPCs), three Flexible PIC Concentrators (FPCs), and two
SCBs. Each FPC holds up to two PICs and each MPC holds up to two Modular Interface
Cards (MICs).
Fully populated, the MX480 router provides an aggregate switch fabric capacity of up
to 5.76 Tbps and line-rate throughput for up to 240 10-Gigabit Ethernet ports, or 24
100-Gigabit Ethernet, or 72 40-Gigabit Ethernet ports.
Table 3 on page 30 lists the MX480 router capacity.
