Different circumstances may require a bandwith limitation on a data transmission link. Furthermore, the bandwith limitation may well be voluntary in order to avoid end equipment monopolization. On the other hand, Response Time is an important characteristic of the link (high speed link) that needs to be preserved for a certain type of traffic, for example, interactive traffic. The pacing mechanism described hereunder provides pacing at the physical layer, implemented on the transmit side. This hardware pacing mechanism is based on the concept of average link use over a certain time interval, under control of the transmitter side. When link use remains under a defined limit, Response Time is preserved (full instantaneous bandwith).
