Case Studies

When most companies consider SD-WAN, they often think about reducing costs and making their network more resilient. Limited SD-WAN knowledge has been one of the biggest challenges in adopting new technologies. Criterion Networks hosted services like Criterion Learning Labs and Criterion designer helped the customer validate interoperability. Partner teams use Criterion SDCloud to demonstrate solutions to customer before physical roll-out.

Enterprise challenge was to connect sites in different countries and a mix of telecom operators. High-availability at various network layer (L3, L2 and Security devices) caused design challenges in failover scenarios. Criterion team was engaged after installation was already completed but there were several design and configuration issues in the production network. It took less than 4 weeks for Criterion Networks to identify design gaps, provide solution and validate.

Partner’s limited capabilities in SD-WAN domain was key issue.  Root-certificates, TLOC extension and control connection configurations were key troubleshooting areas. Criterion’s advanced learning labs focused on each use-case, was immensely useful for partner enablement. It took less than 3 weeks to configure, design and deploy the use-cases in customer network.

Partners inadequate expertise for complex network designs and unavailability of PoC environment for use case validation were major issues. Criterion provided expert SD-WAN Design Consulting, recommendation for best deployment options. Criterion Designer was used for customized network topology and use-cases.
