The Cisco ASR 9000 Series represents an exciting new paradigm in the world of

Carrier Ethernet transport with exceptional scalability, carrier-class reliability,

environmentally conscious design, incredible flexibility, and an enticing new price-

to-performance benchmark.

The Cisco ASR 9000 Series has four form factors: the Cisco ASR 9010 Router, the

Cisco ASR 9006 Router, the Cisco ASR 9922 Router, and the Cisco ASR 9000v

Router. Cisco ASR 9000 Series Routers are designed to provide true carrier-class

reliability using the Cisco IOS XR operating system, comprehensive system

redundancy, and a full complement of network resiliency schemes.

The Cisco ASR 9000 Series also offers service and application-level intelligence

focused on optimized video delivery and mobile aggregation. Finally, the Cisco

ASR 9000 Series is designed to simplify and enhance the operational and

deployment aspects of service-delivery networks.

Key Features and Benefits

• Cisco IOS XR modular operating system—The Cisco ASR 9000 Series leverages the Cisco IOS XR

operating system made famous by the highly successful Cisco CRS Carrier Routing System platform in core

deployments. The Cisco IOS XR operating system is purpose-built for distributed systems such as the

Cisco ASR 9000 Series, and uses a microkernel architecture to achieve true modularity. This modularity

provides the path to nonstop operations during software image upgrades or module changes, without

affecting normal platform operations.

• Fully distributed system—The Cisco ASR 9000 Series operates in a fully distributed fashion; that is, all

packet-forwarding decisions and actions take place on the individual line cards. These high-density Ethernet

line cards are equipped with a specialized network processor that provides a flexible programming

infrastructure with high-density hierarchical quality-of-service (H-QoS) services, security, and integrated

synchronous Ethernet. The distributed nature of the Cisco ASR 9000 Series improves resiliency by adding a

new dimension in scale for features such as bidirectional forwarding detection (BFD) and Ethernet

operations, administration, and maintenance (E-OAM).

• Operationally efficient and redundant hardware—The Cisco ASR 9000 Series provides an infrastructure

where all common components, route switch processors (RSPs), switching fabric, fans, and power supplies,

are completely redundant. In addition, the platform is designed such that power is used on an as-needed

basis depending on system requirements. Power has been modularized for a true pay-as-you-grow

approach, reducing capital expenditures (CapEx) and again providing an operationally efficient deployment.

The Cisco ASR 9000 also provides a space-optimized small-platform option that uses the Series' common

components and retains a central office deployment-ready capability using a patent-pending side-to-back

airflow design.

• Environmentally conscious design—In today's world of increasing awareness of the human impact on the

environment and the resultant fiscal implications, Cisco ASR 9000 Series Routers bring a fresh new

“conscious” approach to product development. From optimal thermal design to the architecture of the power

infrastructure, from the placement of line card components to the pitch of each slot, every design aspect had

one goal in mind: reduced environmental impact through lowered power consumption and decreased

cooling requirements. Even the product packaging process was evaluated to minimize the use of packaging

material and thereby reduce waste at customer locations. The Cisco ASR 9000 Series is an example of the

continued Cisco commitment to efficient and future-friendly product design.

• Network virtualization—Leveraging Cisco's “network virtualization” or nV technology, the Cisco ASR 9000

System offers exceptional pay as you grow scale, carrier-class reliability, and simplified service provisioning.

The ASR 9000v sets the industry benchmark as a virtualized compact carrier-class converged access and

aggregation platform.

• Integrated services capability—The Cisco ASR 9000 Series delivers flexible and highly scalable service

integration through the Integrated Service Module (ISM) allowing operational efficiency and faster time to

market. A Cisco ASR 9000 system populated with ISMs becomes a platform upon which new services and

applications can be layered over time and deployed much more quickly.
