1. Throughput - Rate at which ATM cells depart from the ATM switch.
2.Connection Blocking Probability - Defines the probability of Non-availability of enough resources for generating physical
connections between inlet and outlet .
3. Cell Loss Probability - Defines a no. of data cell that can be handled by a switch queue.
4. Switching Delay - Time required for cell to pass through the ATM switch.
5. Cell Delay Variation - Probability that the switching delay of the ATM switch exceeds the certain value .
