Key Capabilities

Flexible Packaging—Easy Routine Upgrades and Maintenance

Flexible packaging is an enhancement that modularizes and delivers the Cisco IOS XR operating system as RPM packages.

The base software is becoming leaner that contains only required mandatory packages. Other optional packages are separated out and made available as individually installable RPM packages. Users have the flexibility to select and install the services they want by choosing relevant RPMs. Redhat Package Manager (RPM) based delivery of packages enable easier and faster system updates.

Flexible packaging also supports automatic dependency management whereby, while the user is updating an RPM, the system identifies all relevant dependent packages and updates them. The system uses standard LINUX tools to manage dependency during upgrades.

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 Programmability Configuration Guide for the NCS 5000 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 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.

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 Build 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 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 10 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.
