Key Features and Beneﬁts

Cisco 12000 Series Architecture

System Level The Cisco 12000 Series is based on a high speed distributed routing architecture combined with state-of-the-art switching

core that delivers Layer 3 routing at gigabit speeds. TheCisco 12000 Series is optimizedforperformingroutingand packet forwarding functions to transport IPdatagramsacross

a network. The routing function is performed in the Gigabit Route Processors (GRP) responsible for running the routing protocols and building the routing tables from the network topology. This information is then used to build the forwarding tables distributed to the line cards. In addition, the GRP is also responsible for the system control and administrative functions.

• The packet forwarding functions are performed by each of the line card (LC). A copy of the forwarding tables computed

by the GRP is distributed to each of the line cards in the system. Each line card performs independent lookup of a destinationaddress for each datagram received on a local copyoftheforwardingtable and the datagram is switchedacross a crossbar switch fabric to the destination line card.

All cards areinstalled from the frontof the chassisand plug into a passive backplane. This backplanecontains serial lines that interconnect all of the line cards to the switch fabric cards as well as other connections for power and maintenance functions. Each slot in the Cisco 12000 Series has up to 4 serial line connections (1.25 Gbps), one to each of the switch fabric cards (see below) to provide a total capacity of 5 Gbps per slot (2.5 Gbps full duplex). The 12410/12416 utilizes 4 sets of 4 serial line connections in each slot, providing each slot with a switching capacity of 10 Gbps full duplex.

• Switch Fabric

At the heart of the Cisco 12000 Series is a multi-gigabit crossbar switch fabric that is optimized to providehigh capacity switching at gigabit rates.The crossbar switch enableshigh performance for tworeasons: connections from theline cards to a centralized fabric are point-to-point links that can operate at very high speeds; multiple bus transactions can be supported simultaneously increasingthe aggregate bandwidth ofthe system. ACisco 12000 Seriesswitching fabric must be conﬁgured to full fabric(40Gbps for 12008, 60Gbpsfor 12012, 80 Gbpsfor12016, 200Gbps for 12410,and320Gbps for 12416) in order to support all the currentline cards. Please note that the number of fabriccards needed to be installed for a full fabric set will differ according to each chassis.

The switch fabric includes twocard types: Switch FabricCards(SFC) and Clock andSchedulerCards (CSC). Each Cisco 12000 Series must haveat least one CSCin the chassis.The CSC handles requestsfrom line cards,issues grants to access the fabric and provides a reference clock to all the cards in the system to synchronize data transfer across the crossbar. The SFC receives the scheduling information and clocking reference from the CSC cards and performs the switching functions.
