“基于组播组的联邦时间推进策略”一文的商榷

Discussion about “A Multicast Group-Based Strategy of Advancing Time of Federation”

2003年3月第3期15卷中“基于组播组的联邦时间推进策略”一文中,针对计算LBTS过程中“过于保守”的缺陷,将时间管理与数据分发管理相结合,提出了基于组播组的时间推进策略。但其在基于组播组计算LBTS时,并没有充分考虑组播组的定义从而导致错误的结论。鉴于此,指出其不妥之处,并对其错误之处进行了论证。

Proposed in the paper of 2003, 3（15） “A Multicast Group-Based Strategy of Advancing Time of Federation”： Connecting time management with data distribution management of Run Time Infrastructure（RTI）, a time-advancing strategy based on the multicast group is proposed to avoid current “too conservative”strategy for computing Lower Bound on Time Stamp （LBTS）. When computing LBTS, not considering LBTS globally leads to the wrong conclusion, which is the argument.
