Abstract

This document describes the design and implementation process of an automatic failure recovery system on a tactical data link, with the purpose of increasing its reliability during the execution of command and control naval operations. is effort is part of a project that seeks to create a Command and Control System at an operational level. The design of the recovery mechanism begins with the state analysis of the data link system under study, it then, continues with the identification of possible “dead states” and finally, turns to the development of software solutions for each identified failure. is solution considers the communication infrastructure capabilities currently available in the Navy units, so its implementation costs are reduced. is paper also presents the results obtained from the tests carried out in the system, which show that the average failure recovery time was reduced by 50%, increasing the reliability of the analyzed data link.

Highlights

When the units of some military components operate in groups/task forces, tactical information transfer among them is crucial, in order to provide a common tactical view that enables real time coordination of operations.This information exchange must be executed through a system that ensures privacy, that is reliable, user friendly and that, because of bandwidth constraints in the available means of communication (HF - V/UHF), does not overly increase message size.failures that reduce system reliability may occur during the operation
Este documento también presenta los resultados obtenidos a partir de las pruebas efectuadas al sistema, con las cuales se evidencia que el tiempo promedio de recuperación ante una falla se redujo en un 50%, lo que incrementa la fiabilidad del data link analizado
The controlling unit sends the token to the Participating Unit (PU) and since no ACK is received, it repeats the attempt; the design of the system considered only the possibility of the PU reconnecting during that second opportunity, ruling out the option of voluntary or accidental disconnection of the PU; upon reaching this point, the system fails and it cannot find a state in which to operate, completely disconfiguring the network
