3 Revised: April 14, 2016, Network Convergence System 5001 and 5002 Series Routers Opening the Architecture The Network Convergence System 5000 Series offers a high-density, small-form-factor MPLS aggregation router for metro aggregation. It is designed to economically scale large enterprise, over-the-top (OTT), and service provider Data Center networking architectures. The Cisco NCS 5000 Series is an extension to Cisco s routing platform portfolio enabling Service Providers and MPLS enabled data center architectures to offer elastic networks with improved business agility and simplified operations to deliver high-bandwidth mobile, video, and cloud services. It can also operate as an extension shelf of Cisco ASR 9000 Series Aggregation Services Routers using Network Virtualization (nv) technology, consolidating multiple layers in the network and dramatically reducing operational costs. The Cisco NCS 5001 and NCS 5002 are small form factor dense GE/10GE aggregation systems. Powered by industry leading routing operation system, IOS-XR, the system also offers rich functions such as third party application hosting, machine-to-machine interface, telemetry and flexible package delivery. This latest release of Cisco IOS XR operating system opens up the architecture of Cisco IOS XR using a 64-bit Linux-based operating system to deliver greater agility, automation and simplicity, while reducing the cost of operating the networks. The new innovations in this release enable incremental builds, agile workflows, and modular delivery of software, while also offering the capability to host third-party applications on Cisco routers. These innovations deliver these benefits by enabling traditional and web service providers to converge their data centers and wide area network (WAN) architectures, by making networks more programmable, and by facilitating tighter integration with popular IT configuration and management tools. Key Enhancements Data Models Faster Programmatic and Standards-based Configuration Data models are a programmatic and standards-based way of configuring and collecting operational data of a network device, replacing the process of manual configuration. Using Data models, Cisco IOS XR operating system supports the automating of configurations that belong to multiple routers across the network. Data models are written in a standard, industry-defined language, which can define a new configuration and state an existing configuration on a network. Traditional CLI-based configurations, are proprietary, cumbersome, and highly text-based. Managing automated operations on a large network using CLIs is a challenge. Cisco IOS XR supports the YANG data modeling language. YANG can be used with the Network Configuration Protocol (Netconf) or with grpc (google-defined Remote Procedure Calls) to automate programmable network operations. Data models allow administrators to customize settings easily and automatically, without wasting time on manual configuration. To get started with using data models, see the Obtain Data Models section in Cisco IOS XR Data Model Configuration Guide for the NCS 5001 and 5002 Series Router. Application Hosting Efficient Leverage of Third-Party Tools Application hosting gives administrators a platform for leveraging their own tools and utilities. Cisco IOS XR 6.0 supports third-party off-the-shelf applications built using Linux tool chains. Users can run custom applications cross-compiled with the software development kit that Cisco provides. Application hosting is offered in two variants: Native and Container.

4 Integrating applications, configuring management tools, and auto provisioning was a challenge with traditional 32-bit QNX OS. With networking rapidly moving to virtual environments, the need for a network operating system that supports operational agility and efficiency through seamless integration with existing tool chains became a key requirement for our customers. Cisco IOS XR uses a 64-bit Linux-based operating system that simplifies the integration of applications, configuration management tools, and industry-standard zero touch provisioning mechanisms to meet the DevOps style workflows for service providers. To access the SDK to build packages that use the Linux distribution offered by Cisco, and to host applications natively, see Building RPMs for Native Application Hosting section in the Cisco IOS XR Application Hosting Configuration Guide. Telemetry Push Towards Smarter Visibility Streaming telemetry lets users direct data to a configured receiver for analysis and troubleshooting purposes in order to maintain the health of the network. This is achieved by leveraging the capabilities of machine-to-machine communication. Traditionally, organizations used the pull model to collect data, where a client pulls data from network elements. This pull model, however, does not scale when there is more than one network management station in the network. These traditional techniques do not cater to all the underlying information of the router, and they require manual intervention. Tuning a network based on real-time data is crucial for seamless operation of the network. Instead of a pull model, using a push model to continuously stream data out of the network in the order of few seconds enhances the operational performance and reduces the troubleshooting time. Data can be pushed out at intervals determined by the administrator, at a cadence as low as 30 seconds. Using sophisticated algorithms, a back-end server can then analyze data received from the Cisco IOS XR operating system. The data can be encoded in JavaScript Object Notation (JSON) or Google Protocol Buffers (GPB). This analysis enables back-end management systems to measure and even predict control-plane and data-plane trends. A telemetry policy file is used to define the data to be generated and the cadence at which the data is to be streamed. To create a policy file and get started with streaming telemetry data, see the Create Policy File section in Cisco IOS XR Telemetry Configuration Guide.
