The Cisco® ASR 9910 and ASR 9906 Route Switch Processor (A99-RSP) is the next-generation system processor for the Cisco ASR 9910 and ASR 9906 Routers (Figure 1). 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 9910 and ASR 9906 RSP 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 9910 and ASR 9906 RSP 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.
The ASR 9910 and ASR 9906 RSP 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. Some examples include:
● Hybrid switch fabric architecture along with Cisco ASR 9910 and ASR 9906 Fabric Cards:
◦ Distributed switch fabric architecture
◦ Uses the integrated switch fabrics located on the RSPs
◦ Also uses the switch fabrics located on dedicated switch fabric cards
◦ Control of up to seven switch fabrics (two located on the RSP and five on dedicated switch fabric cards) to provide same scalability and high availability as on the Cisco ASR 9922 Router and ASR 9912 Router chassis
◦ Multistage, low-latency, non-blocking 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 a 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 9910 and ASR 9906 RSP 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.

Software
The Cisco ASR 9900 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 9900 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); Multi-Chassis 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 9900 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 Series system configuration requiring high multiple-dimensional scale requires the service-edge optimized route switch processor model to support the increased system scale.
Timing synchronization is an integral part of traditional circuit-based networks, so the availability of equivalent functions in next-generation Ethernet-based architectures has quickly become a critical requirement. Cisco ASR 9900 Series chassis have standards-compliant Precision Time Protocol Version 2 (PTPv2), GPS, DTI, and BITS connections on the route switch processor, along with SyncE support natively on the line cards, which gives mobile providers ample options for time and frequency synchronization. Additionally, the Cisco ASR 9900 Route Switch Processor supplies centralized clocking functions throughout the system, providing consolidated timing distribution and recovery to and from the line cards.
