ASR 9000 Series Routers
ASR 9000 Series Routers
Product Overview
The Cisco
®
ASR 9000 Series Aggregation Services Routers deliver unprecedented 10-Gb and 100-Gb port
density, scale, service flexibility, and high availability into Carrier Ethernet, Broadband Network Gateway (BNG),
Data Center Interconnect (DCI), Data Center WAN, mobile backhaul transport, video on demand (VoD) and
business VPN services transport networks. The routers are powered by Cisco IOS
®
XR Software, an innovative,
self-healing, distributed operating system designed for always-on operation.
Cisco IOS XR Software Release 4.2.0 provides new software and hardware feature support for Cisco ASR 9000
Series routers. This release further enhances the role of the Cisco ASR 9000 Series in the IP Next-Generation
Network (NGN). The Cisco IP NGN delivers a Carrier Ethernet design for converged, resilient, intelligent, and
scalable transport of consumer, business, wholesale, and mobile services. Applications supported within this
framework include residential broadband services with high-scale Ethernet subscriber and session awareness,
Internet Protocol Television (IPTV) and VoD, Layer 2 (L2) and Layer 3 (L3) business-VPN services, DCI, and next-
generation mobile backhaul transport.
New Hardware Features
Cisco IOS XR Software Release 4.2.0 introduces support for the following new hardware.
●
Route Switch Processor (RSP) 440: The Cisco ASR 9000 Series RSP 440 is designed to deliver the high
scalability, performance, and fast convergence required for today’s and tomorrow’s video, cloud, and mobile
services. The Cisco RSP 440 provides a superior set of features that deliver unprecedented scale, service
flexibility, and high availability. The RSP includes an active-active, low latency, nonblocking switch fabric
architecture that provides service intelligence, traffic prioritization, scalability, and high availability. Cisco RSP
440 also provides superior network timing capabilities with support for centralized Building Integrated Timing
Supply (BITS), DOCSIS
®
Timing Interface (DTI) timing reference systems, Precision Time Protocol (PTP) or
IEEE 1588-2008, and bidirectional time of day (ToD) with 10-MHz and 1-pps interfaces. The RSP is available
in Service Edge Optimized and Packet Transport Optimized models. The Service Edge Optimized version
offers the higher amount of memory essential for large-scale comprehensive service deployments.
