In the system it is required to synchronize a file server’s clock to within ±1 millisecond. Discuss this in relation to Cristian’s algorithm.
What will be an ideal response?
To synchronize a clock within ± 1 ms it is necessary to obtain a round-trip time of no more than 18 ms, given the minimum message transmission time of 8 ms. In principle it is of course possible to obtain such a round- trip time, but it may be improbable that such a time could be found. The file server risks failing to synchronize over a long period, when it could synchronize with a lower accuracy.
