分布式时间戳同步(DTS,distributed timestamp synchronization)技术能够较好地满足端信息跳变的同步需求,但仍存在一定程度的同步失败。对DTS技术进行了改进(IDTS,improved DTS):额外开启一个前置和一个后置端信息用于接收同步失败的数据分组。首先构建了端信息跳变系统的服务模型并给出了IDTS技术的通信协议,在此基础上分析说明了IDTS技术的有效性和安全性,最后通过实验验证了IDTS技术的实践价值。
Distributed timestamp synchronization (DTS) could satisfy the requirement of synchronization for end hop- ping, but still had some degree failure of synchronization. An improved scheme of DTS (say IDTS) was proposed by pro- viding two additional endpoints to receive the unsynchronized packets. It established models and definitions for end hop- ping system at first, then provided protocol for IDTS, analyzed the effectiveness and security of IDTS. Finally, the em- pirical results show the practical value of IDTS.
