Alarmas comunitarias basadas en arquitecturas SDN e IOT

Abstract

EXECUTIVE SUMMARY Citizen security systems of today more than ever represent a tool of high impact and vital importance for the Society of the 21th Century. Its technological maturity has allowed it to be included in several geographical areas as part of government policies and has even managed to be constitutionally catalogued as a right of all citizens. With the growth of the demand for citizen security systems and the continuous technological advances linked to it. The data that transits over the computational networks that support such systems, constantly suffer from saturation problems and bottlenecks caused by the lack of traffic management policies and quality of service. In traditional network topologies, data is considered equally without distinguishing protocol or priority; because central routers contain policies preloaded and preconfigured by hardware manufacturers. However, in network segments where traffic management is required to be optimized; it is necessary to create custom policies for each of the devices that make up that network. In terms of network control, this represents another major obstacle during the expansion, migration or upgrade of large networks such as those intended for monitoring community alarms that include critical video, audio and data traffic. The research proposes a restructuring of traditional data networks, using two emerging technologies designed for decongestion. In the first instance, a software-defined network architecture (SDN) is used to separate the control plane from the data plane on the network switches and thereby solve the problems of expansion, migration or upgrade of large networks. Second, the infrastructure of community alarms activated by radio frequency devices is replaced by an IoT network architecture with MQTT communications protocol. Finally, we present the results of a bandwidth analysis of a traditional network without control policies over which digital audio services (VoIP), video surveillance (CCTV), data and IoT control packets pass; demonstrating that critical traffic services tend to capture 80% of the total bandwidth of the network. And in addition, the advantages and results of a software-defined network topology designed to work synergistically with IoT protocols are evaluated. In addition to providing simplicity and simplicity during the implementation of traffic and quality of service policies configured through a web environment that can be implemented and replicated in high-demand network environments.
