Abstract: A system providing efficient cataloging and storage of data-storage devices. The system comprises a plurality of removable holders adapted to hold at least one of the data-medium-containing articles. Each holder is adjustably mounted within a support comprising three cylindrically shaped members. While engaged within the support, the holders are free to move independently along the cylindrically shaped members to permit holders to be added or removed from any position within the indexed plurality of stored holders. The system is modular and may be expanded in size and capacity. The system may be integrated within furnishings.

Abstract: Method and apparatus for monitoring data traffic through a cable data network in order to guarantee a minimum and maximum bandwidth and burst length. Traffic statistics are kept as credits that are only updated as needed. Each cable modem in the network is assigned a limit on the maximum amount of traffic that it may transmit and receive depending on the service level that the subscriber has purchased. When that limit is exceeded, traffic for that modem will no longer allowed to pass through the system.
