Many clock synchronization protocols based on message passing, e.g., the Network Time Protocol (NTP), assume symmetric network delays to estimate the one-way packet transmission time as half of the round-trip time. As a result, asymmetric network delays caused by either %natural one-way network congestion or malicious packet delays can cause significant(More)
Time synchronization is crucial to many distributed applications. Network Time Protocol (NTP) is a widely adopted time synchronization protocol. To synchronize a master and slave accurately, NTP measures the round-trip time (RTT) of a synchronization packet between them. It assumes that the two one-way transmission delays are equal. Thus, by measuring the(More)
