The propagation delay diameter refers to the maximum time required to transmit a data packet from the sender to the receiver in a network. This assumption helps the PHANTOM protocol consider the uncertainty of network delay during its design, thereby optimizing the algorithm and improving system performance.\nFirstly, assuming the network's propagation delay diameter helps to model the uncertainty in network  transmission processes with certainty. In practical applications, network delay may be affected by various factors (such as network congestion, router failures, etc.) that cause unpredictable fluctuations."}]}],"pr":"c0f68e671df63e597be4d12dbbccfb306d8a50cf9d22a5b14ca7a116c67062f0"}
