Bandwidth on demand is a data communication technique for providing additional capacity on a link as necessary to accommodate bursts in data traffic, a videoconference, or other special requirements. The technique is commonly used on dial-up lines and wide area networks (WANs) to temporarily boost the capacity of a link. Some call it "rubber bandwidth" because the capacity can be increased or decreased as needed. It is also called dynamic bandwidth allocation or load balancing. A similar technique is bandwidth on time of day, which refers to providing additional capacity at specific times of the day. |
