ASR-9912-SFC110

The Cisco ASR 9900 Switch Fabric Card 2 , Switch Fabric Card S  and Switch Fabric Card T are the next-generation switch fabrics for the Cisco ASR 9922 Router, ASR 9912 Router, ASR 9910 Router and ASR 9906 Router, supporting high-density 100 Gigabit Ethernet line cards.The system architecture of the Cisco ASR 9900 Switch Fabric Card 2 (ASR 9900 SFC2), Switch Fabric Card S (ASR 9900 SFC-S) and Switch Fabric Card T (ASR 9900 SFC-T) is designed to accommodate new programmable deployment models and convergence of Layer 2 and Layer 3 services, as required by today’s wireline, Data-Center-Interconnect (DCI), and Radio Access Network (RAN) aggregation applications.

The ASR 9900 SFC2, SFC-S, SFC-T features provide exceptional scale, service flexibility, and high availability. Examples include:

●     Distributed switch fabric architecture

●     Support for up to seven ASR 9900 switch fabric cards SFC2 to provide scalability and high availability on the ASR 9922 and ASR 9912 Routers

●     Support for up to five ASR 9900 switch fabric cards SFC-S to provide scalability and high availability on the ASR 9910 Router

●     Support for up to five ASR 9900 switch fabric cards SFC-T to provide scalability and high availability on the ASR 9906 Router

●     Multistage low-latency nonblocking architecture

The switch fabric is configured as a single stage of switching with multiple parallel planes, and it is responsible for transporting packets from one line card to another. Each fabric plane is a single-stage, nonblocking, packet-based, store-and-forward switch that works with the Cisco ASR 9000 Route Processor 2 and Cisco ASR 9000 Route Switch Processor RSP to support traffic management using the centralized Virtual Output Queue (VOQ) arbitration of the route processor.

The ASR 9922 and ASR 9912 chassis provide 6 + 1 redundancy using an all-active fabric-controllers configuration model that allows for distribution of the traffic load across all seven switch fabrics, taking advantage of the processing capacity of all. If a failure occurs on one fabric card, the remaining 6 active cards continue to forward traffic in the system, with hardware support for zero packet loss on fabric-card Online Insertion and Removal (OIR). Because all fabric cards are active and forwarding traffic, they are all ready to assume the full traffic load.

Compared to the ASR 9922 and ASR 9912, which can accommodate up to seven fabric cards, the ASR 9910 and ASR 9906 use up to five dedicated fabric cards in combination with the fabrics built in on the two route switch processors. As a result, the ASR 9910 and ASR 9906 can provide seven fabrics to switch the traffic.

The ASR 9910 and ASR 9906 chassis also provides 6 + 1 redundancy using an all-active fabric-controllers configuration model that allows for distribution of the traffic load across all seven switch fabrics, taking advantage of the processing capacity of all. If a failure occurs on one fabric (dedicated fabric card or route switch processor’s built-in fabric), the remaining six active fabrics continue to forward traffic in the system, with hardware support for zero packet loss on fabric-card Online Insertion and Removal (OIR). Because all fabric cards are active and forwarding traffic, they are all ready to assume the full traffic load.

Third-generation high-density 100 Gigabit Ethernet line cards support up to seven fabric controllers, whereas second-generation Cisco ASR 9000 Series line cards support up to five fabric controllers. The switch fabric is fully redundant, with one copy of the fabric on each fabric card, and each fabric card carries enough switching capacity to meet the chassis throughput specifications.

Cisco IOS XR Software

The Cisco ASR 9000 Series Aggregation Services Router delivers superior scale, service flexibility, and high availability into access and aggregation networks. It is powered by Cisco IOS XR Software, an innovative self healing, distributed operating system designed for always-on operation. Cisco IOS XR Software supports a Software-Maintenance-Update (SMU) capability, which allows bug fixing or even small feature releasing without interrupting existing services. It also supports Field-Programmable Device (FPD) upgrades, which can be used to update Field-Programmable Gate Arrays (FPGAs), ROM monitor (ROMmon), and more, while systems are running.

Cisco ASR 9000 Series Carrier Ethernet applications include business services such as Layer 2 VPN (L2VPN) and Layer 3 VPN (L3VPN), Internet Protocol Television (IPTV), Content-Delivery Networks (CDNs), and mobile backhaul transport networks. Features supported include Ethernet Services; L2VPN; IPv4, IPv6, and L3VPN; Layer 2 and Layer 3 Multicast; IP over Dense Wavelength-Division Multiplexing (IPoDWDM); SyncE; Ethernet Operations, Administration, and Management (EOAM) and Multiprotocol Label Switching (MPLS) Operations, Administration, and Management (OAM); Layer 2 and Layer 3 Access Control Lists (ACLs); Hierarchical Quality of Service (H-QoS); MPLS Traffic Engineering Fast Reroute (MPLS TE-FRR); MultiChassis Link Aggregation (MC-LAG); Integrated Routing and Bridging (IRB); Cisco Nonstop Forwarding (NSF) and Nonstop Routing (NSR); Point-to-Multipoint Traffic Engineering (P2MP-TE); Lawful Intercept; Smart Call Home (SCH); and Multigigabit Service Control (MGSCP).

The Cisco ASR 9000 Series Multiservice Edge (MSE) and Ethernet MSE (E-MSE) capabilities allow enterprises to offer powerful business VPN services with strong Service-Level Agreement (SLA) enforcement. Such services typically require simultaneous scale increases across multiple dimensions, for example, the number of Virtual Route Forwarding (VRF) interfaces, IPv4 and IPv6 route scaling, Bidirectional Forwarding Detection (BFD) sessions, and instances of Border Gateway Protocol (BGP) Cisco NSR interfaces. A Cisco ASR 9900 system configuration requiring high multiple-dimensional scale requires the Service-Edge (SE) optimized route processor model to support the increased system scale.

Product specifications

Table 3 provides details about the ASR 9900 SFC2, which supports the ASR 9912 and ASR 9922 chassis (thereby providing common sparing) and the ASR 9900 SFC-S and SFC-T, which supports the ASR 9910 and ASR 9906 chassis, respectively. The ASR 9922, ASR 9912, ASR 9910 and ASR 9906 systems are designed to the same high standards of performance and reliability, and they feature the same power and thermal innovations.
