The ASR 9900 RP2 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 Cisco ASR 9900 RP2 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:
- 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 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 and 100-Mbps Ethernet port
- Bidirectional time of day (ToD) with 10-MHz and 1-pps interface
