MX960 Application Services Modular Line Card Description
The Application Services Modular Line Card (AS MLC) is an X86-based card for MX960, MX480, and MX240 routers to deliver integrated application service solutions. The first application that network operators can take advantage of is the Junos Content Encore system, a high-throughput, solid state storage platform for media rich content delivery. Additionally, the AS MLC can serve as the platform for Juniper Networks JunosV App Engine, powering a host of network applications directly embedded into your MX Series 5G Universal Routing Platforms.
The Application Services - Modular Carrier Card (AS-MCC) has reached End of Life. See End of Life Announcement: AS-MCC.
The AS MLC is modular and decouples CPU and storage in individual field-upgradeable units. The AS MLCs are designed to enable application throughput up to 50 Gbps and a storage capacity of 400 gigabytes (GB) of NAND Flash.
MX960 AS MLC Function
The AS MLC provides modular processing and modular storage. Installed on the AS MLC, the Junos Content Encore system operates as a caching application, in either HTTP reverse proxy mode or HTTP transparent proxy mode, to manage client requests for content and the distribution of the content to clients from origin servers. In the future, the AS MLC will run other Juniper Networks router services and applications, and serve as a virtualized platform for third-party applications. The AS MLC provides Ethernet switching and high-speed fabric interface to MX routers. Graceful Routing Engine switchover is also supported on the AS MLC.
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.
The AS MLC Modular Carrier Card (AS MCC), the carrier card of the AS MLC, fits vertically in the front of the MX960 router (see Figure 2).
AS MLC Components
Each AS MLC consists of the following components:
AS MLC Modular Carrier Card (AS MCC), which fits vertically in front of the MX960 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 NAND Flash capacity for modular storage
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 that contains the host processor and supporting peripherals
LED on the AS MCC, which displays the status of the AS MLC
