A9K RSP880 TR
The Cisco ASR 9000 Route Switch Processor 880 (RSP 880) is the system processor for the Cisco ASR 9010 Router, ASR 9006 Router, and ASR 9904 Router. It supports high-density 100 Gigabit Ethernet line cards and provides backward compatibility with the Cisco ASR 9000 Series second family of line cards. The Cisco ASR 9000 RSP 880 system architecture 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 9000 RSP 880 brings the time-tested and robust carrier-class capabilities of Cisco IOS XR Software to the Carrier Ethernet edge. The operating system supports true software process modularity. And it allows 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.
Cisco ASR 9000 Route Switch Processor 880 The ASR 9000 RSP 880 is designed to deliver the high scalability, performance, and fast convergence required for today’s and tomorrow’s demanding video, cloud, and mobile services. These features provide exceptional scale, service flexibility, and high availability:
Integrated switch fabric architecture: Distributed switch fabric architecture Multistage low-latency nonblocking architecture Service intelligence and traffic prioritization Superior network-timing capabilities with support for: Centralized Building Integrated Timing Supply (BITS) Precision Time Protocol (PTP), or IEEE 1588-2008, through dedicated 10-Mbps or 100-Mbps Ethernet port Bidirectional time of day (ToD) with 10-MHz and 1-pps interfaces Route-Switch-Processor Types
The ASR 9000 RSP 880 is available in service-edge-optimized and packet-transport-optimized models. The service-edge-optimized version offers the higher amount of memory that is essential for large-scale, comprehensive service deployment. Both versions of the route switch processor support service-optimized, as well as transport-optimized, line cards. Different line cards can be mixed on the same chassis, providing maximum design flexibility.
Highly scalable fabric Designed to support high 1-, 10-, and 100-Gbps port densities Provides built-in scalability for investment protection Fabric capacity 880 GB nonredundant 440 GB redundant Distributed forwarding-plane architecture Allows line cards to support independent forwarding for enhanced performance and scale Memoryless switch fabric Provides transparent nonblocking, low-latency packet forwarding Virtual output queuing and arbitration Offers service intelligence with prioritization of traffic (unicast and multicast) Provides efficient congestion-management mechanism and avoids problems related to head-of-line blocking Two 32-GB solid-state drives (SSDs) Allows storing of core dumps and helps reduce the system mean time to repair (MTTR) Processor Has 8 cores, 1.9 GHz
