Bit rate reservation is effected with the aid of a reservation cell containing a requested bit rate transmitted from a calling terminal to a called terminal via switching nodes of an asynchronous network. At each node, a bit rate increase request is at least partially satisfied even if the difference...http://www.google.de/patents/US5600645?utm_source=gb-gplus-sharePatent US5600645 - Bit rate reservation at switching nodes of an asynchronous network
