Abstract
A gigabit passive optical network or other type of optical communication network comprises an optical line terminator that transmits data in a downstream direction to multiple optical network units. The optical network units transmit data in an upstream direction to the optical line terminator. In one aspect of the invention, the optical line terminator is operative to allocate upstream bandwidth among the optical network units, to measure usage of the allocated upstream bandwidth by the optical network units, to process the measured usage to determine a predicted variation in usage of upstream bandwidth by the optical network units, and to alter the allocation of the upstream bandwidth based on the predicted variation.
