Cisco ASR9K FABRIC CONTROLLER 4G MEMORY network switch module

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.

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 IOSXR 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.
