Abstract
A method and apparatus for finding a better path through an integrated services digital network (ISDN) involves collecting a first data set about the current path and a second data set about a proposed replacement path. Each gateway or tandem public or private telephone network through which the path travels updates the respective data set with information about its link. The data sets are compared according to preselected criteria. The preferable connection is retained and the less preferable connection is released.
