Constructing capable and scalable parallel computers or connecting contemporary networks efficiently makes multistage switching networks essential and significant devices. This is why they remain an interesting field of research and are being continually improved. This paper introduces a new idea-a new architecture-to ameliorate the behaviour of the networks' connection points.The proposed novel construction accommodates multiple internal paths and a fan-out at the end. Via this study, basic features of this introduced fabric (such as cost, reliability, and performance measures) are presented in a quantitative manner. Moreover, some comparisons-especially in terms of complexity, cost, and reliability-with other similar modern constructions that also enclose multiple internal routes are shown. This study reveals that the proposed multistage system improves performance metrics, fault tolerance, and reliability and indicates that due to its properties, this innovative device can be used in the commercial sector.
