Apparatus and method for dynamically allocating channels for transmission of data

摘要

In a data communication system having a two or more channels of varying bandwidth and cost it is desirable to select a channel that meets data transfer needs and minimizes cost. In basic rate ISDN a D channel is typically used to provide low bandwidth service. When a user needs more bandwidth, the user switches to a B channel or two B channels. The automatic channel selection method and apparatus described provides a user with adjustable parameters to customize performance of a ISDN service unit. An anti-thrashing algorithm is provided to minimize frequent call setups and disconnects.
