Design and Implementation of a Scalable and Secure Network Infrastructure for a Medium-Sized Enterprise

This report presents the detailed design and realization of the training of a network infrastructure for a medium-sized business. The aim is to provide versatile, secure, and efficient networking for the operational requirements of nearly 30 employees, plus dedicated rooms for server, printing, conference, and surveillance purposes. The network employs a ring topology for efficient data transfer and utilizes a combination of static routing, IP addressing, and subnetting so as to perform optimally and leave space for possible expansion as required. Some of the salient features include secured entry through keycard systems, wireless and wired connectivity, departmental segmentation via subnets, and redundancy offered by multiple routers and switches. This design of the enterprise architecture is aimed at preventing downtimes, supporting growth, and safeguarding secure and uniform access for all users.
