In order to support the IT service over an ATM network, IP datagram should first be segmented into the number of ATM cells before transmitting them over the ATM network. As ATM does not give the cell loss recovery, loss of any of these cells will result in loss of the entire IP packet. For these reasons, consider the information given below:
a) PC = Cell loss rate in the ATM network
b) n = number of cells required to transmit a single IP datagram
c) PP - IP-packet loss rate
Utilizing the information above, deduce an expression for the PP, and provide comment on resulting expression. Also, what the ATM services would you utilize in order to obtain the best possible performance?
