Kosm Case Study 1: Enterprise SDWAN Migration

Problem Statement

An enterprise customer chose Cicso’s Viptela SDWAN solution to help leverage more DIA (Direct Internet Access) for their branch and data center locations. Due to their unfamiliarity with the product and the complexity of the migration, there were major concerns around downtime for extended change windows as well as the ramifications of migrating existing circuits into a more dynamic routing environment.


Leveraging Kosm’s native automated discovery tool we were able to quickly model the existing routing paths and then fully replicate the environment down to the specifics of the routing protocols and critical traffic patterns. In an iterative process we then began introducing the new WAN devices and uncovered several potential design issues in the virtual environment.


Successful deployment and migration! The exact configuration and time of application were worked out and fully validated in advance on the Kosm virtual testbed. The migration was smoothly executed and the network operations team was off and running as they already had hands-on experience with management of the new Viptela environment.
