How to Connect 4 Venues With Communication Services Through a Secure Network.

The following article gives a global perspective of a design process of a private network, which offers data services (file transfer), voice (calls) and video (videoconferences), as well as providing quality of service (QoS). This Project has been developed for a research center such as the National Directorate of Research, Science and Technology “DNICYT” part of the Military School of Engineering, operating in four academic units.

To achieve its objective, this project aims to isolate the entire network of the National Directorate of Research, Science and Technology “DNICYT”, being independent of the main network of the Military School of Engineering “EMI”, beyond being housed inside of this, implementing perimeter security with an intrusion prevention system “IPS” and the implementation of a virtual private network for the connection with the different academic units.

This article presents the design steps of the services, implementing a PBX software that is basically a telephone exchange, which has the virtue of also providing the videoconferencing service; including, the implementation of an FTP server for file transfers.

In terms of quality of service, the project proposes the calculation of necessary bandwidth, the CODEC that best adapts to our needs and the quality of service technique that will be used to provide the best experience to the end users, (administrative personnel, teachers and students) of this research center.

Based on the first idea presented below, which shows a completely isolated red in the form of an individual block with the ability to connect to external networks, without compromising its security.

In this way the following high-level design is made, which shows in broad strokes the components of this network, giving an idea of ​​how the interconnection of these sub-sites could be.

Finally we have the emulation of the network in the GNS3 software, which shows the operation of this red.
