A cell flow rate control method for an ATM switch can cope with various UPC forms while using the same hardware arrangement. The cell flow rate control method includes the steps of preparing a conformance condition table in which are stored conformance conditions for each connection determined for each cell loss priority in an ATM cell; and employing, for each cell loss priority, a plurality of conformance test components in accordance with the conformance condition stored in the conformance condition table.

FIG. 1 is a diagram illustrating a first embodiment of the present invention with no tagging;
FIG. 2 is a diagram illustrating a second embodiment of the present invention with tagging;
FIG. 3 is a diagram illustrating a third embodiment to effectively operate the first and the second embodiments;
The preferred embodiments of the present invention will now be described while referring to the accompanying drawings. The same reference numerals are used throughout to denote corresponding or identical components in the drawings.
FIG. 1 is a diagram showing a first embodiment of the present invention, which corresponds to FIGS. 11 and 12. In the examples in FIGS. 11 and 12, test components C.sub.0 and C.sub.0+1 are processed for a cell for which CLP=0, and only test component C.sub.0+1 is processed for a cell for which CLP=1.
On the other hand, in the first embodiment in FIG. 1, for each connection, provided as a data table T.sub.a are a test component that should be processed for a cell for which CLP=0, and a test component that should be processed for a cell for which CLP=1 or that should be processed for a cell when tagging is performed. More specifically, in the table T.sub.a are stored routing information (steps S01 through S04) for each connection relative to cells for which CLP=1 and CLP=0.
