Abstract:

In view of the clock synchronization in distributed system,three technologies are brought forward,namely the clock synchronization architecture based on passiveresponse server,clock error statistics based on continuous timedstamp,and algorithm for delay computation and clock retaining based on given clock precision.With software clock synchronization,these technologies improve the clock synchronization precision and reduce the network communication flow and expense of CPU in distributed system greatly to synchronize clock.

Key words: clock synchronization;clock retaining;continuous timedstamp;distributed system
