What is our primary use case?
I use Cisco Crosswork Network Automation for closed-loop network automation, mass configuration deployment, and real-time telemetry to manage traffic optimization during large-scale network consolidations. This is from one of the major post-merger integrations that I was involved with, where I used Cisco Crosswork Network Automation's optimization engine and telemetry to dynamically steer traffic from congested links before decommissioning duplicated sites. By automating segment routing policies based on real-time latency and bandwidth thresholds, I was able to cut over maintenance windows by roughly half, with zero packet loss or subscriber disruption.
How has it helped my organization?
Cisco Crosswork Network Automation has structurally lowered my organization's OPEX by basically eliminating manual traffic re-routing tasks, and has reduced maintenance windows roughly by half. It has also preserved enterprise SLAs and protected revenue during complex network migrations because it can handle traffic congestion automatically.
I saw an estimated 25% reduction in recurring network operations OPEX by automating routine traffic tasks. Change windows that used to take four to six hours per maintenance event were compressed to 90 minutes roughly, with zero manual intervention or rollbacks.
What is most valuable?
I think the standout capability of Cisco Crosswork Network Automation is the closed-loop remediation that it offers, which shifts operations from reactive firefighting mode to proactive traffic management. The only initial learning curve is the initial multi-vendor API connection, but once established, I think it scales effortlessly as you add more operations to the product.
The best features Cisco Crosswork Network Automation offers are the optimization engine for dynamic segment routing and the real-time path calculations, which stand out the most for me. If you combine it with model-driven telemetry, it provides you granular visibility that basically helps you prevent congestion before it impacts service and customer experience.
Cisco Crosswork Network Automation replaces manual routing adjustments by automatically recalculating and re-routing segment paths the moment latency spikes or link saturations occur. In my daily workflow, this reduces routine traffic engineering tickets by roughly 60 to 70%, frees up my operations team from firefighting, and allows them to focus purely on strategic capacity planning, customer retention, acquisition, and churn reduction tasks.
My final thoughts on the features would be the zero-touch provisioning and change management automation, which are quite critical for my organization as they let you push mass configuration updates across thousands of nodes within minutes. You can also add automated pre- and post-validation checks, which basically eliminates human error during change windows, and that can be very costly.
What needs improvement?
I think the biggest improvement needed for Cisco Crosswork Network Automation is its multi-vendor support, which needs to be more robust. Ingesting telemetry and deploying policies across third-party gear still requires heavy custom API development, so lowering the initial cluster deployment complexity and flattening the learning curve for non-Cisco gear would significantly accelerate time to value.
I think the technical documentation for Cisco Crosswork Network Automation is pretty solid, especially for greenfield Cisco environments. However, troubleshooting multi-vendor API issues requires senior Cisco TAC involvement, so if they provide more plug-and-play SDK templates and clear integration patterns for non-Cisco equipment, that would make third-party deployments much smoother.
For how long have I used the solution?
I have been using Cisco Crosswork Network Automation for three to four years across large-scale service provider transformations and network consolidation programs.
What do I think about the stability of the solution?
The accuracy is very high for the traffic anomaly detection and path computation parts because it grounds its response and reasoning in real-time telemetry and deterministic versus probabilistic network topologies. I would say reliability is rock solid since the recommendations need to be validated against defined policy thresholds before any action can be taken, which eliminates any false positives in production routing.
What do I think about the scalability of the solution?
I think the scalability of Cisco Crosswork Network Automation is rock solid. You can push out configuration changes and pre- and post-health checks to thousands of nodes within minutes, and I have used it in live deployments in excess of 50,000 sites many times.
How are customer service and support?
I think the TAC solution support for Cisco Crosswork Network Automation is quite responsive and highly knowledgeable on the core feature. However, solving complex custom integrations and third-party APIs can require escalations as it usually becomes a blame game between different parties and takes time to resolve at whose end the problem actually lies. Overall, the support is quite dependable.
Which solution did I use previously and why did I switch?
I relied on legacy Cisco Network Services Orchestrator combined with custom Python and Ansible scripts before using Cisco Crosswork Network Automation. I switched because NSO alone lacked real-time closed-loop remediation, and the switch made proactive traffic steering possible, which simply would not have been feasible during those rapid network consolidations.
How was the initial setup?
I evaluated Juniper's Paragon Automation product, Nokia Network Services Platform, and Ericsson's Cloud Automation Platform before choosing Cisco Crosswork Network Automation, which I selected primarily due to its superior integration with my existing routing architecture and its end-to-end telemetry pipeline.
What was our ROI?
I have already mentioned that it has delivered real ROI in terms of man-hours saved and OPEX reduction, and helped me strategize better in some of those complex network consolidation projects that I do. However, I would deduct two points because most of my clients have multi-vendor environments, and if that integration with third-party vendors were smoother, I would happily add the two points that I took out.
What other advice do I have?
I would say that when looking into using Cisco Crosswork Network Automation, start with focused use cases like telemetry and visibility before turning on closed-loop automation. Additionally, audit your multi-vendor environment early so you can budget time for custom API integration.
Cisco Crosswork Network Automation is a dependable and high-performing platform for large-scale transport network automation, and when paired with the right operation discipline, you do see the ROI on that. My overall review rating for this product is 8 out of 10.
