Every Internet Service Provider on the face of the Earth needs to use a Quality of Experience middle-box on their network. A middle-box gives you visibility into your network: latency, jitter and bufferbloat only become apparent when you look. Spot congestion and latency spikes at every level of the network. A middle-box gives you proactive monitoring: identify the customers who are having problems before they call you. And most importantly, a middle-box gets rid of support calls. By actively managing bufferbloat, enhancing perceived latency and proactively pacing packets you can immediately improve your customers’ quality of experience. In our experience, this massively reduces the volume of support calls-and costs to service them. A Quality of Experience middle-box allows also for more aggressive but safer over-subscription rate. PS: Bandwidth is a lie.
