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.

Abstract: 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.

Key words: software-defined network, OpenFlow protocol, rules placement
