Abstract

The multiplexing of shaped on-off sources on an asynchronous transfer mode (ATM) link is addressed. In particular, an N-level shaper is analyzed. It modulates the source output bit rate on the basis of the buffer occupancy level. A very accurate analytical model describing its behavior is provided. Such a model allows an accurate description of the shaper output flow characteristics. A simple analytical model is also proposed for an ATM multiplexer in order to evaluate the advantages arising from the source shaping. The accuracy of the analytical results comes out from the comparison with the simulation ones. Numerical results show the effectiveness of the proposed shaping mechanism. They demonstrate that a substantial increase of the number of multiplexable sources is possible, for a given value of cell loss probability
