Cisco ASR-9900-RP-TR Network Switch Module Networking

The Cisco® ASR 9900 Route Processor - is the first generation of system processors available for the Cisco ASR 9912 Router and ASR 9922 Router chassis. The Cisco ASR 9900 Route Processor is designed with a system architecture to accommodate convergence of Layer 2 and Layer 3 services as required by today’s service providers in wireline, data center interconnect (DCI), and Radio Access Network (RAN) aggregation applications.

The Cisco ASR 9900 Route Processor 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. 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 9900 Route Processor 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 unprecedented scale, service flexibility, and high availability:

Switch fabric architecture along with Cisco ASR 9900 Fabric Cards:
- Distributed switch fabric architecture
- Control of up to seven Cisco ASR 9900 Switch Fabric Cards to provide scalability and high availability on 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) and DOCSIS® Timing Interface (DTI) timing reference systems
- Precision Time Protocol (PTP), or IEEE 1588-2008, through dedicated 10/100-Mbps Ethernet port
- Bidirectional time of day (ToD) with 10MHz and 1-pps interfaces
