Cisco Crosswork Change Automation and Health Insights provide a programmable remediation system that supports closed-loop operations based on configurable KPIs and feedback-driven workflows.

Product Overview

Cisco Crosswork Network Automation enables service providers to proactively manage their end-to-end networks, with a suite of machine-learning, intent-based and closed-loop solutions to ensure faster innovation, extraordinary customer experiences, and operational excellence.

On-premise solutions provide actionable insights with automated network orchestration, accelerating mean-time-to-value by monetizing agile new services, as well as minimizing mean-time-to-remediation to avoid network degradation and customer issues. Cisco Crosswork Cloud provides multiple SaaS solutions that provide operational insights and validation of network health and security with the agility and scale of the cloud.

Cisco Crosswork Change Automation: The Cisco Crosswork Change Automation application automates the process of deploying changes to the network. The user defines the orchestration via an embedded Ansible Playbook; then configuration changes get pushed to Cisco Network Services Orchestrator (NSO) to be deployed to the network.

Cisco Crosswork Health Insights: Cisco Crosswork Health Insights is a network health application that performs real-time Key Performance Indicator (KPI) monitoring, alerting, and troubleshooting. The Cisco Crosswork Health Insights application enables programmable monitoring and analytics. Cisco Crosswork Health Insights provides a platform to address changes to the network infrastructure dynamically. Cisco Crosswork Health Insights builds dynamic detection and analytics modules that allow operators to monitor and alert on network events based on user-defined logic.

Closed Loop Remediation

The ability to identify and remediate problems in the network before customers notice is critical for network operators. With the Crosswork Change Automation and Health Insights closed loop function, service providers can automate the process of discovering and remediating problems in the network by allowing an operator to match an alarm to pre-defined remediation tasks. These tasks will automatically be performed once a defined Key Performance Indicator (KPI) threshold has been breached.

Remediation can be implemented with or without the network operator approval, depending on the setting and preferences of the operator.

Using closed loop remediation reduces the time it takes to discover and repair a problem while minimizing the risk of making a mistake and creating an additional error through high-stakes manual network operator intervention.

Platform Support Information

Each Health Insights instance can support a single interface KPI streaming at a 60s cadence across 300K simultaneous interfaces. The realized scale can vary significantly (higher or lower) depending on the type and number of KPIs, desired cadence and relative distribution of interfaces across devices. The system is less sensitive to the number of devices compared with the total number of interfaces. In addition, adding more compute resources beyond the recommended VM profile can provide a boost in performance.

Cisco Crosswork supports Model-Driven Telemetry (MDT) on the following platforms.

This information is provided with the assumption that you plan to stream telemetry in band with other data traffic. If you want to stream telemetry via a separate management VRF, you must use Cisco IOS XR version 6.2.2 or later.
