60-byte text string stored in the JCS management module NVRAM that conveys configuration information to the Routing Engines (blades) in the JCS chassis.

Interface concentrator on which PICs are mounted. An FPC is inserted into a slot in a Juniper Networks router. See also PIC.

A configuration that enables PSDs on the JCS1200 platform to communicate on a peer-to-peer basis without requiring external links. Inter-PSD forwarding is achieved by using tunnel PICs that reside on each PSD. The PSDs communicate over logical interfaces configured on the tunnel PICs.

Chassis management hardware and software included used to access and configure the Juniper Control System (JCS) platform.

Hardware device that connects Routing Engines in the Juniper Control System (JCS) chassis to a Juniper Networks router and controls traffic between the two devices. For redundancy, the JCS chassis can include two JCS switch modules.

OEM blade server customized to work with Juniper Networks routers. The JCS chassis holds up to 12 single Routing Engines (or 6 redundant Routing Engine pairs). The JCS1200 chassis connects to up to three T Series routers, enabling the control plane and forwarding plane of a single interconnected platform to be scaled independently.

Physical Interface Card. A network interface-specific card that can be installed on an FPC in the router.

One or more Flexible PIC Concentrators (FPCs) on a Juniper Networks router matched with a Routing Engine (or redundant pair) on the JCS1200 platform to form a secure, virtual hardware router.

A pair of redundant Routing Engines on a Juniper Networks router connected to the switch fabric on the Juniper Control System (JCS) platform. The configuration on the Routing Engines on a single Juniper Networks router provides the RSD identification and the configuration of up to eight Protected System Domains (PSDs).

A physical interface that is owned by the Root System Domain (RSD) on which logical interfaces can be shared by multiple Protected System Domains (PSDs). Each individual logical interface is assigned to a different PSD. On the PSD, each assigned logical interface is configured and peered with an uplink tunnel interface (ut-fpc/pic/slot), which transports packets between the PSD and the shared interface on the RSD.
