Bias-Free Language
The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Assure high-performance network services with confidence
Imagine being able to execute intent-based, proactive service assurance across your entire multivendor, multidomain network. With Cisco Crosswork® Network Automation’s automated assurance capabilities, you are empowered to optimize service performance, enabling you to deliver and monetize differentiated services that not only meet but surpass customer expectations.
Traffic continues to grow exponentially, and modern networks, with their multivendor, multidomain, and multilayer attributes, are becoming vastly more complex to manage. Yet despite this, customers still expect flawless network services.
Proactive, automated assurance is the key for Communications Service Providers (CSPs) who manage high-performance networks to deliver consistently exceptional experiences and adhere to the rigorous performance demands of the critical network services required by large enterprises.
Crosswork’s automated assurance approach pairs advanced network automation with high-resolution performance monitoring for proactive, intent-based service assurance. See how your network performs end-to-end and monitor service health in real time with the ability to find and fix issues before customers are impacted, even as you rein in capital and operational expense.
● Expedite troubleshooting: Identify and resolve problems before they affect service by leveraging end-to-end topology-based visualization and multilayer correlation to pinpoint the root cause of existing and potential problems.
● Optimize Quality of Experience (QoE): Monitor Key Performance Indicators (KPIs) in real time and make changes instantly with software-defined network control.
● Unlock new revenue: Deliver high quality services consistently and offer robust Service-Level Agreements (SLAs) to differentiate your services in competitive markets.
● Simplify service lifecycle management: Provision, assure, and optimize your network seamlessly with automated transport slicing, real-time monitoring, machine learning-powered analytics, and advanced traffic engineering.
● Reduce costs: Simplify assurance operations and increase efficiencies across multivendor, multilayer, and multidomain transport networks.
Assurance is a key part of enabling superior digital experience. Yet the complexity of current assurance operations makes it challenging to deliver high-quality services consistently. Traditional assurance tools are simply not equipped to handle today’s dynamic networking environment as the number of users, devices, and demands for services continue to skyrocket.
● Processes are mostly manual, which delays time to resolution and creates inefficiency.
● Troubleshooting is reactive and typically takes place after issues are identified.
● Context on performance issues is limited, with noise from alarms and alerts preventing a quick response to customer-impacting issues.
Complex assurance operations are time-consuming and slow, leading to poor service quality, high operating costs, and, ultimately, customer churn.
Drive a unified, and simpler, top-down approach
Crosswork’s approach to intent-based service assurance is multilayered yet simplified, unifying domains as part of a top-down, service-centric approach.
The primary goal of the Service Operations Center (SOC) is to ensure that SLAs meet customer requirements. Operators view performance metrics on a single dashboard within Crosswork Network Controller and receive alerts in real time if a service is degrading or SLAs are being violated. Cisco Provider Connectivity Assurance (formerly Accedian Skylight), actively monitors end-to-end service performance using embedded assurance sensors or probes, sending data and KPIs to the network controller dynamically to proactively identify service issues.
Provider Connectivity Assurance sends granular reporting on network service performance to Crosswork Network Controller for deeper investigation when a degradation has been detected and flagged. Provider Connectivity Assurance also enhances the customer experience with a personalized end-user portal designed with user-specific features to cater to different groups. This approach not only improves engagement but also opens up avenues for CSPs to offer additional capacity proactively when the portal detects potential issues.
Crosswork Network Controller + Provider Connectivity Assurance Integrated Solution
At the second layer, the Network Operation Center (NOC), operators use active topology maps enabled by Crosswork Hierarchical Controller (HCO) to drill down and find the root cause of issues. HCO is a multidomain controller with visibility that enables the NOC team to determine if issues are confined to a single domain or span multiple domains.
Equipped with these insights, domain-specific Subject Matter Experts (SMEs) can pinpoint and isolate components that impede network performance and service quality, taking corrective action to fix them.
The Crosswork platform seamlessly integrates and facilitates closed-loop, automated assurance operations, enabling a streamlined flow of information that is accessible and actionable for various teams. Whether it’s the SOC, NOC, or domain SMEs, a clear and comprehensible view ensures quick understanding and fast remediation.
Deliver outstanding experience
An intent-based approach to service assurance helps you quickly understand if, where, and why services are degrading to accelerate issue resolution. You’ll know when changing traffic conditions impact SLAs, and you’ll be able to automatically optimize the network. You can also leverage ML-assisted predictive analytics to mitigate anomalies before service is disrupted and customers are impacted.
Crosswork’s advanced automation solutions work together to provide end-to-end visibility into network performance and service health. Continuous, data-driven insights make it easy to optimize dynamically and take swift action to resolve anomalies for consistent service quality, performance, and end-user experience. Intent-based automated assurance is how you deliver the outstanding experiences and differentiated services your customers expect.
Provider Connectivity Assurance orchestrates and fully automates monitoring and assurance capabilities through the Crosswork Network Automation platform. Crosswork Network Controller and Crosswork Network Services Orchestrator drive automation decisions based on real-time network performance information and proactive alerting. Here’s how it works:
● Assurance Sensors are deployed using Crosswork NSO as part of the automated workflow when new transport layers or VPNs are defined using service intent. Activation testing templates and other automated test sequences are used to activate service assurance.
● NSO triggers these templates using the NETCONF and YANG API to achieve closed-loop automation. This actively verifies that services work after being provisioned by NSO and continue to perform over the service lifecycle.
● Performance data and events can be further analyzed in Provider Connectivity Assurance or can be sent back to Crosswork Network Controller to correlate KPIs with other events coming from the infrastructure. This process supports SLA management, AI/analytics, databus, and end-customer SLA reporting portals.
