CDV TOLERANCE FOR MAPPING CELLS BETWEEN ATM AND PHYSICAL LAYERS

For a customer premise node with multiple terminal equipment, a multic onnection shaper is required to regulate cells toward the customer loo p such that they will be treated as conforming by the enforcer at the public user network interface. However, when setting the arguments of the enforcing algorithm (e.g. generic cell rate algorithm), the cell d elay variation (CDV) between shaper and enforcer must be taken into co nsideration. The authors calculate the CDVs for mapping cells between the ATM layer and the physical layer at the shaper and enforcer.
