The Internet is rapidly becoming an electronic agent for commerce, entertainment, communication, and information retrieval. New network-enabled intranet applications and powerful desktop computers are driving an exponential increase in network traffic. Service Providers and Enterprises are rapidly deploying packet switching infrastructures to handle this tremendous growth in data traffic. The Gigabit Switch Router (GSR) 12000 series is Cisco"s premier routing product family designed and developed for the core of service provider and enterprise IP backbones. The GSR family includes two models - the Cisco 12008 and 12012. The 12008 model provides a 40Gbps switch fabric and has eight slots that can be used to support interfaces ranging from DS3 to OC-48c/STM-16c. This model can support a maximum of 7 OC-48c/STM-16c interfaces for a total of 28Mpps switching capacity. The 12012 model provides a 60Gbps switch fabric and has 12 slots that can be used to support interfaces ranging from DS3 to OC-48c/STM-16c. This model can support a maximum of 11 OC-48c/STM-16c POS interfaces for a total of 44Mpps switching. The Cisco 12000 GSR products are used in the core of the largest IP backbones in the world today.
The GSR 12000 series products are architected to meet the bandwidth, performance, services and reliability requirements of today"s IP core backbones: Modular, multigigabit crossbar switching fabric allows bandwidth to scale in either 40Gbps (12008) or 60Gbps (12012). High density, high speed interfaces ranging from DS3 to OC48c/STM16c, that can be easily added as needed. Packet over SONET/SDH interfaces at 155Mbps (OC3/STM1), 622Mbps (OC12c/STM4c) and 2.5Gbps (OC48c/STM16c) data rates Asynchronous Transfer Mode (ATM) interfaces at 155Mbps (OC3/STM1) and 622Mbps (OC12c/STM4c) data rates LAN interfaces 1Gbps (Gigabit Ethernet) and others to follow Frame based interfaces (PPP, Frame Relay) at 45Mbps (DS3), 155Mbps (OC3/STM1), 622Mbps (OC12c/STM4c) Channelized interfaces at 622Mbps (OC-12) channelized to 45 Mbps (DS-3) and 622Mbps (OC-12/STM-4) channelized to 155 Mbps (OC-3/STM-1) Scalable Performance Innovative switch fabric design supports virtual output queues (VoQs) that eliminate head-of-line blocking (HOLB) and increase overall system efficiency and supports partial fulfillment for multicast traffic where replication of multicast traffic is performed by the switch fabric. Distributed architecture delivers scalable Layer 3 switching performance through intelligent line cards that can be added incremental interfaces are required Micro-programmable application specific integrated circuits (ASICs) based queuing provides line rate forwarding for unicast and multicast traffic that fills SONET/SDH transmission facilities to capacity, ensuring best return on investment on expensive bandwidth Industry leading Cisco IOS software State of the art queuing and congestion management techniques: Random Early Detection (RED), Weighted RED (WRED) and Deficit Round Robin (DRR) that provides an enhanced Weighted Fair Queuing mechanism MPLS/Tag Switching support to deliver the scalable traffic engineering features Carrier Class Design Redundancy in all key system components, i.e. processors, switch fabric, line cards, power and cooling, to minimize network disruption in the event of a failure Hot-swap capability enables components to be added or removed without service disruption Switch fabric redundancy provides fail-over to backup fabric with no data or user session loss APS/MPS enables SONET/SDH resiliency capabilities for providing interface redundancy Network Equipment Building System (NEBS) and European Telecommunications Standards Institute (ETSI) compliance for installation in service provider central-offices. System Level The GSR 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. The GSR is optimized for performing routing and packet forwarding functions to transport IP datagrams across 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 destination address for each datagram received on a local copy of the forwarding table and the datagram is switched across a crossbar switch fabric to the destination line card. All cards are installed from the front of the chassis and plug into a passive backplane. This backplane contains 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 GSR has up to 4 serial line connections (1.25Gbps), one to each of the switch fabric cards (see below) to provide a total capacity of 5Gbps per slot (2.5Gbps full duplex). The major components of the GSR are - Switch Fabric, Gigabit Route Processor and Line Cards. Switch Fabric At the heart of the GSR is a multi-gigabit crossbar switch fabric that is optimized to provide high capacity switching at gigabit rates. The crossbar switch enables high performance for two reasons: connections from the line cards to a centralized fabric are point-to-point links that can operate at very high speeds; multiple bus transactions can be supported simultaneously increasing the aggregate bandwidth of the system. A GSR switching fabric must be configured to full fabric (40Gbps for 12008, 60Gbps for 12012)in order to support all the current line cards. The switch fabric includes two card types: Switch Fabric Cards (SFC) and Clock and Scheduler Cards (CSC). Each GSR must have at least one CSC in the chassis. The CSC handles requests from 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. It provides the following key functions: Gigabit speed interconnections between line cards (5Gbps per slot) State-of-the-art scheduling algorithm combined with Virtual Output Queues to eliminate head-of-line blocking (HOLB) achieving 99% efficiency Hardware based multicast High Availability via redundancy (1:4 for SFC, 1:1 for CSC) with loss-less failover and hot-swap capability. Gigabit Route Processor The Gigabit Route Processor (GRP) is a high performance engine that provides the routing intelligence for the Cisco GSR family. It is dedicated to determining the network topology and calculating the best path across the network. The GRP has the following hardware characteristics: 200MHz R5000 CPU Optionally up to 256 MB CPU DRAM (default 64 MB) 512KB Layer 2 cache 512KB configuration NVRAM 8 MB boot Flash Two PCCMIA Type II software upgrades Ethernet (RJ45 and MII connectors) for Network Management access Local Console and modem ports (DB-25 EIA/TIA-232c) It provides the following key functions: Process Interior Gateway Protocols (IGP) such as IS-IS, IGRP, EIGRP to determine the network topology Process External Gateway Protocols (EGP) such as BGP Create and maintain the routing table (up to 1 million route entries) Distribute and update Express Forwarding (EF) tables on the line cards and maintain copies of each line card"s EF tables for card initialization General maintenance functions such as diagnostics, console support and line card monitoring In-band management through SNMP MIB, Telnet, BOOTP and TFTP Line Card Line cards connect the GSR to other devices via electrical or optical media. The line cards are designed for the transmission of IP packets over PPP, Frame Relay or ATM interfaces. The features and functions of the line cards are interface specific. POS interfaces on the GSR enable connections to other GSR 12000 or other Cisco routers, such as Cisco 7500 or 7200 via optical interfaces. These interfaces can be circuits provisioned over a SONET/SDH infrastructure or dark fibers (native fiber links) connections or wavelengths of Wave Division Multiplexing (WDM) systems. The GSR offers the following POS interfaces: 4 OC3/STM1 ports per line card 1 OC12c/STM4c ports per line card 4 OC12c/STM4c ports per line card 1 Channelized OC12 port (to DS3) per line card 1 Channelized OC12/STM4 port (to STS3c/STM1) per line card 1 OC48c/STM16c ports per line card ATM interfaces on the GSR enable connections to other GSR 12000 or other Cisco routers, such as Cisco 7500 or 7200 via ATM networks. The GSR offers the following ATM interfaces: 4 OC3/STM1 ports per line card 1 OC12c/STM4c ports per line card Gigabit Ethernet (GE) interfaces on the GSR enable connections to other GSR 12000 or other Cisco routers, such as Cisco 7500 or 7200 via fiber optic links. The GSR offers the following Gigabit Ethernet interfaces: 1 GE port per line card Cisco 12000 Series - Gigabit Switch Routers

At the heart of the GSR is a multigigabit crossbar switching fabric that provides synchronized gigabit-speed interconnections for all of the other cards in the system. The switching fabric for the Cisco 12012 and 12008 consists of up to four switching cards, supplemented by a fifth card that provides 1:4 or 1:1 redundancy. The switching cards for the Cisco 12008 and 12012 are not interchangeable. The following table shows the valid configuration for the switching fabric.
The switch fabric for the 12008 and 12012 consists of two different type of assemblies: the Clock/Scheduler Controller (CSC) and the Switch Fabric (SFC). As the name implies, the CSC contains the switch fabric, but also includes the system clock and fabric scheduler. The SFC contains the switch fabric only. The CSC and SFC assemblies are unique to each chassis type and are therefore, not interchangeable.
