2.2 Infraestructura <strong>de</strong> Red: Los brazos <strong>de</strong> la AUI<br />

<strong>La</strong> Autopista <strong>de</strong> la Información proporciona conectividad<br />

a todas las localida<strong>de</strong>s <strong>de</strong> la Provincia <strong>de</strong> San<br />

Luis, con más <strong>de</strong> veinte habitantes. Para ello utiliza<br />

una red IP, que es la más gran<strong>de</strong> red gubernamental<br />

<strong>de</strong> la República Argentina.<br />

<strong>La</strong> red IP <strong>de</strong> banda ancha, <strong>de</strong> la AUI, es <strong>de</strong> tecnología<br />

híbrida ya que utiliza enlaces <strong>de</strong> fibra óptica, radio<br />

enlaces y enlaces satelitales. Esta red está compuesta<br />

por un po<strong>de</strong>roso backbone principal en forma <strong>de</strong><br />

anillo y una capa <strong>de</strong> agregación, y última milla, con<br />

topología estrella. También, se dispone en la ciudad<br />

capital y Villa Merce<strong>de</strong>s <strong>de</strong> una infraestructura <strong>de</strong> red<br />

metropolitana <strong>de</strong> fibra óptica que se conectan al backbone<br />

principal.<br />

Figura 5: esquema Backbone IP / Figure 5: Backbone IP diagram<br />

The Information Highway provi<strong>de</strong>s connectivity to all localities that<br />

have more than twenty inhabitants in the whole Province of San Luis.<br />

To achieve this, an IP net is used, the largest governmental net in Argentina.<br />

The AUI’s broadband IP net uses hybrid technology since it uses fiber<br />

optic links, radio links and satellite links. This network is composed by<br />

a powerful main backbone, shaped as a ring and an aggregation layer,<br />

last mile with star topology. There is also, in the capital city and in<br />

the city of Villa Merce<strong>de</strong>s, a metropolitan fiber optic net infrastructure<br />

that connects to the main backbone.
