Analysis and Simulation of the NTP On-Wire Protocols

 · Let p be the probability that a packet is correctly received, then P = p 2 and Q = 1 - p 2.Substituting in (2) we see that the limit approaches 1, which confirms the liveness assertion. In the on-wire protocol there are no retransmission's; every packet carries at least one state variable which changes for every packet sent.
