This book will serve as a reference tool for any researcher in the field of networking and telecommunications to familiarise themselves with information and communication techniques and to encourage those who wish to enter this field. This work is a demonstration of our knowledge acquired during our training in computer science, specifically in networking and telecommunications, but also a practice of scientific research. This work will also enable the improvement of the information and communication system, both technical and administrative, by means of the media, so that the INSS can exchange information internally on its inter-network. The book is divided into three chapters: The first is on Generalities and Scope; the second is on Analysis and Design of the New System and the final chapter which is the third will focus on Discussions and Recommendations.
