Check whether your internet uplink comfortably covers your subscribers at their busiest, and get a warning before you run into congestion. If you do not know your oversubscription ratio, the tool can work it out from your real usage.
Your customers almost never all use their full speed at the same moment, so it is normal to sell more total speed than your internet uplink (your backhaul) could carry if everyone maxed out at once. The oversubscription ratio is how far you stretch that. This tool checks whether your backhaul comfortably covers realistic busy-hour demand, and warns you before congestion starts slowing people down.
Not sure what any of this means for your ISP? That is exactly what we do. Network Design and Optimization covers backhaul sizing, aggregation design, and the monitoring that tells you when to upgrade before customers notice.
