The Cisco® ASR 9000 Series Route Switch Processor (RSP) is a scalable, low-power, next-generation Carrier Ethernet platform with a system architecture specifically designed to accommodate service providers' unique convergence requirements of Layer 2 Ethernet transport plus Layer 3 services (Figure 1).
Figure 1. Cisco ASR 9000 Series Route Switch Processor
Cisco ASR 9000 Series Aggregation Services Routers offer one of the industry's highest-capacity Carrier Ethernet platforms. These routers are optimized for aggregation of dense 10 Gigabit Ethernet and 100 Gigabit Ethernet connections.
In addition to a higher capacity and scale, the Cisco ASR 9000 Series offers:
• Distributed forwarding and control planes for higher performance
• Modularized system components in both hardware and software, isolating failure and faults to subsystem and component
• Hardware-based signaling for the fabric: support for zero packet loss on switchover
• Built-in redundancy in hardware components such as the route switch processor, switch fabric, control-plane chassis control bus, and power supplies, thereby avoiding a single point of failure
The Cisco ASR 9000 Series operates in a fully distributed fashion, meaning that all packet-forwarding decisions and actions take place on each individual line card. The Cisco ASR 9000 Series Line Cards provide flexible programming infrastructure with high-density hierarchical quality-of-service (HQoS) services, security, and integrated Synchronous Ethernet (SyncE). The distributed nature of the Cisco ASR 9000 Series also presents itself in the control plane. The distributed control plane facilitates scale in features such as Bidirectional Forwarding Detection (BFD) and Ethernet operations, administration, and management (EOAM), which improve resilience and provide comprehensive instrumentation.
Cisco ASR 9000 Series routers bring the time-tested and comprehensive carrier-class capabilities of Cisco IOS® XR Software to the Carrier Ethernet edge. The operating system supports true software process modularity. The capabilities of Cisco IOS XR Software allow each process to run in separate protected memory, including each routing protocol along with multiple instances of control, data, and management planes supported.The software also supports distributed route processing.

The Cisco ASR 9000 Series 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 while scaling system capacity up into the Tbps.
Cisco ASR 9000 Series Carrier Ethernet applications include business services such as Layer 2 VPN (L2VPN) and L3VPN, IPTV, Content Delivey 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, EOAM and Multiprotocol Label Switching (MPLS) OAM, Layer 2 and Layer 3 access control lists (ACLs), H-QoS, MPLS Traffic Engineering Fast Reroute (MPLS TE-FRR), Multichassis Link Aggregation (MC-LAG), Integrated Routing and Bridging (IRB) and Cisco Nonstop Forwarding (NSF) and Nonstop Routing (NSR).
Cisco IOS XR Software Releases 4.0.0 and 4.0.1 introduce the support for a comprehensive portfolio of shared port adaptors (SPAs) to facilitate the multiservice edge (MSE) and Ethernet MSE (E-MSE) capability on the Cisco ASR 9000 Series. The Cisco ASR 9000 Series MSE and E-MSE capabilities allow enterprises to offer powerful business VPN services with strong SLA (service-level agreement) 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) NSR interfaces, and so on. A Cisco ASR 9000 Series system configuration requiring high multiple dimensional scale requires an RSP with 8G memory to support the increased system scale.

Both systems are designed to the same high standards of performance and reliability, feature the same power and thermal innovations, and can share RSPs, line cards, power entry modules (PEMs), and power supplies, for maximum flexibility in your network planning.
