These days, there's more and more talk about the Internet signal problem in various sectors, and the IT resources needed to overcome it. At present, the use of a single internet signal in large companies prevents them from producing good results in a short space of time in the event of breakdowns. When there's a torrential downpour, the Internet connection poses a problem, and especially when a signal-receiving antenna is offset from the satellite orbit, there's signal distortion or loss. This work enables us to provide an effective solution to this problem, using several Internet Service Providers without incurring the expense of buying a router for each provider. We therefore propose to set up a routing strategy based on line separation, and a relay system in the event of a signal interruption from one of the ISPs. We have configured a single corporate router with two ISPs: MICROCOM for the one-stop shop, and VODANET for staff or user Internet use.
