Abstract: This paper outlines the theoretical and practical issues of the algo rithms at first, then it analyses this solution from the general rules for the c ost of space and time. The above all points out that the solution can resolve th e VP's clock management problems. The outstanding characters of this solution ar e as following: merging the physical clock algorithm and logical clock algor ithm perfectly and improving the availability of clock management of through ad optin g the HOT-STANDBY methods.
