摘要
针对NTP技术中对网络时间延时测量的不足,提出了在网络支持下的高精度时间同步方法。该方法采用数据包丢失技术,通过比较传送的数据报文中的特殊队列值和所经过的路由器中数据包的排队队列长度值来决定是否对当前数据报文丢弃。仿真实验表明,该方法具有很好的可行性。
In order to improve measured precision of time delay in Network Time Protocol （NTP）, a highly precise time synchronization method was proposed in network. The method adopted the self-discarding packet technique that was a means of determining transfer by comparing the queue length of the transiting router with a specified queue value on the packet. Simulation results show that this method has a very good feasibility.
