摘　　要：针对联合采用超时机制和通配符匹配机制的规则放置问题,提出了基于时空联合的规则放置算法TSRPM,综合考虑了规则在流表中的逗留时间和规则的匹配空间,以确定规则的放置方案.实验结果表明,所提算法产生的规则放置方案能够有效提高规则命中率,降低分组拒绝率.Time-space based rules placement method（TSRPM） is proposed for solving the problem of rules placement utilizing both timeout and wildcard match schemes. The sojourn time and space of a rule are both considered to decide rules placement approach in TSRPM. The results of simulation show that TSRPM can improve the match rate and reduce the packet refused rate.
