This treatment makes utilities in the Industrial Estate full and difficult to maintain. As a result of the full utility, it results in a slow process of handling disturbances. So that 56% of tenants in industrial estates are dissatisfied with ICT services because the SLA delivered is not more than 90%. Therefore, it is necessary to study the interconnection method and the selection of devices that can meet the demands of customers and service providers. This study presents a step-by-step design and implementation of the network construction used as a Sharing Infrastructure. Researchers use the PPDIOO framework in designing the network to be implemented. This research is used to design a reliable, scalable and can be monitored. Furthermore, especially to meet the expectations of Industrial Estate Management, Service Providers and tenants.
