  • Cisco IOS Xrv 9000 Router Data Sheet
    Data Sheet Cisco IOS XRv 9000 Router Product Overview The Cisco IOS® XRv 9000 Router implements the feature set of Cisco IOS XR Software. Running on virtualized general x86 compute platforms, it complements existing physical Cisco® router platforms that rely on Cisco IOS XR Software, such as Cisco Network Convergence System routers, Cisco ASR 9000 Series Routers, and Cisco Carrier Routing System (CRS) platforms. Now, service providers can enhance their operational excellence and offerings based on physical routers - and move them easily to a virtual form factor. The Cisco IOS XRv 9000 Router (Figure 1) offers greater agility, improved network efficiency, lower capital and operational expenditures, and the ability to efficiently scale network capacity up and down, based on demand. Main Features of the Cisco IOS XRv 9000 Router ● End-to-end solution with network functions virtualization (NFV) infrastructure, virtual network functions, and service orchestration and management ● Based on the extremely resilient, stable, and feature-rich Cisco IOS-XR Software, with the same northbound and management features as Cisco IOS XR Software, which helps ensure smooth integration with existing OSS and business support systems (BSS) ● High-performance data plane with service provider edge features, such as Quality of Service, access control list, and NetFlow ● Architecture that separates the control plane and data plane, which allows for scaling up and down with multicore, multisocket, and multiserver systems The Cisco IOS XRv 9000 Router can be deployed in the following two ways: ● For control plane functionality, such as a virtual route reflector ● As a high-performance data plane, based on an X86-optimized code base, developed specifically for Cisco nPower network processor units (NPUs), and the Intel® Data Plane Development Kit (DPDK) Figure 1.
