Integrated with application forwarding on MX Series routers, the AS MLC provides
increased service flexibility with reduced power and space requirements for the network
infrastructure.
AS MLC Components
Each AS MLC consists of the following components:
•
AS MLC Modular Carrier Card (AS MCC), which fits horizontally in front of the MX480
router, includes two slots for the Application Services Modular Storage Card (AS MSC)
and Application Services Modular Processing Card (AS MXC)
• AS MXC with 64 GB RAM for processing
•
AS MSC with 400 GB of NAND Flash capacity for modular storage
NOTE: The AS MCC, AS MXC, and AS MSC are hot-removable and
hot-insertable.
•
Switch fabric interfaces to the chassis
•
XM ASIC chip, which owns and manages the packet data memory built from external
DDR3 memory chips, the fabric queuing system, a portion of the WAN queuing system,
and the host queuing system
•
LU ASIC chip, which performs all functions relating to header processing including input
processing, route lookup, classification, filtering, policing, accounting, encapsulation,
and statistics
• Midplane connectors and power circuitry
•
Processor Mezzanine Board (PMB), which contains the host processor and supporting
peripherals.
• LED on the AS MCC, which displays the status of the AS MLC
