Cisco’s Next Generation of Routers
Cisco Systems’ new family of Internet switching and routing products, referred to collectively as the Cisco 12000 Series Gigabit Switch Routers, consists of the following models:
•Cisco 12016 Gigabit Switch Router—A 16-slot, carrier-class platform that supports Internet protocol (IP) switching capacity of up to 160 Gbps.
•Cisco 12012 Gigabit Switch Router—A 12-slot version that supports IP datagram switching capacities ranging from 15 to 60 Gbps.
•Cisco 12008 Gigabit Switch Router—An 8-slot version that supports IP datagram switching capacities ranging from 10 to 40 Gbps. The Cisco 12008 is the subject of this document.
The architecture of the Cisco 12000 Series Gigabit Switch Routers provides the following networking capabilities and features:
•Scalable bandwidth—Supports high-speed transmission of IP datagrams through use of Cisco 12000 series line cards. The network interfaces reside on the line cards, providing connectivity between the router’s switch fabric and external networks.
•Scalable performance—Supports multi-gigabit bandwidth switching capacities ranging from 5 to 60 Gbps, providing high-performance support for IP-based networks and wide-area networks (WANs).
•Scalable services—Supports sophisticated congestion management, multicast services, and quality-of-service (QOS) features.
•Carrier-class design—Supports extensive SONET/Synchrononous Digital Hierarchy (SDH) integration; supports a hot-swapping capability for field-replaceable units (FRUs).
