One of the topics that concerns the way computer networks are designed, is the single-vendor and multi-vendor solutions. Where the performance and operation of your network depends on which model you choose for your enterprise, and the future risks aligned with such models. This study outlines the strengths and average price ranges of multiple vendors in the past 2 years (2018 and 2019), practical cases in which each model works, a case study done by Gartner, and finally, recommendations that can help push the design practices when it comes to network design.
