A system for recovering from ground bounce during a boundary scan test is disclosed that includes operationally transitioning a Test Access Port controller from any of at least three undetermined controller states induced by the ground bounce to a determined controller state. In the erasewrite operation, first, a low-frequency clock signal as a selection clock signal is input by a low-frequency clock control signal to a charge pump. The services manger then oversees the admission of the flow to appropriate traffic classes in each determined network and the obtaining of a DSCP value for each network. The management server refers to a configuration reservation table to confirm whether free time is available in the same period about all target network devices. The light passes through the lower layer, LC layer and upper layer.
