| 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. |
