Abstract
Communication system bandwidth reservation management techniques are disclosed. If actual usage of a reserved amount of bandwidth in a communication system reflects a reduced usage state, a determination is made as to whether the reserved amount of bandwidth is to be adjusted. A portion of the bandwidth that has been reserved for a Video-on-Demand session, for example, may be released when playback of a video is paused. A time-based series of reduced usage states may be defined such that reserved bandwidth is gradually released if the reserved bandwidth is not actually used for a period of time. Embodiments of the invention may be implemented in various forms of apparatus, methods, data structures, and Graphical User Interfaces (GUIs).
