The bandwidth of a virtual circuit is changed when the aggregate bandwidth available on path(s) to an adjacent ATM device (through which the VC is provided) changes. The change of bandwidth may be implemented by changing the QoS parameters associated with the virtual circuits. Thus, for example, when...http://www.google.de/patents/US7697431?utm_source=gb-gplus-sharePatent US7697431 - Managing the bandwidths of virtual circuits when the aggregate bandwidth to an adjacent device changes
