摘要
为解决分布式系统中时钟同步问题,提出了时钟服务器被动应答式的同步结构、基于连续时间戳统计平均值的误差、时延计算方法和基于设定时钟精度的时钟保持技术。在软件同步的情况下,提高了同步精度,减少了因时钟同步而产生的网络通信量、各分布式系统的CPU开销。
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.
