Abstract
A guaranteed frame rate (GFR) service providing apparatus and method for an ATM switch is provided. A cell conformance portion applies a test to each cell in an input frame with respect to generic cell rate algorithm (GCRA), cell loss priority (CLP) bit, and maximum frame size (MFS), sets the conforming bit (CB) of each cell in the frame to a conforming value if all cells of the frame pass the test, and sets the CB of each cell in the frame to a non-conforming value if at least one cell of the frame does not pass the test. A buffer management portion allocates cells with CBs set to a conforming value to a high priority queue, allocates cells with CBs set to a non-conforming value to a low priority queue, transmits the cells allocated to the high priority queue with a minimum cell rate (MCR) guaranteed, and transmits the cells allocated to the low priority queue at a cell rate allowed by a bandwidth available in a network.
