数据是这个样子

现在想这么做
1、把时间和Flags中间的数据一样的行(即这些数据192.168.90.120.3711 158.158.158.120.81 放到一起 顺序不要打乱，还是按照时间从小到大的顺序
2、对于归类到一起的行，以最后一位是[S]的为分割，取中间的时间差  但注意不是两个[S]对应的时间直接做差
而是前一个[S]的下一行的时间和后一个[S]的上一行的时间做差，注意数据可能会被多个[S]分割  需要每个[S]之间的都按照这样做差     
另外如果数据的第一行或最后一行不是[S]   也要跟下一个[S]或上一个[S]的时间 按照上面规则做差
3、这样会得到srcip > dstip [这里是2中得到所有时间差]  然后对时间差进行计数 ，一共有多少个   再求时间差的总和
4、最后结果应该是
srcip1 > dstip1 时间个数 时间和
srcip2 > dstip2 时间个数 时间和

搞了好久没搞出来  关键是不知道怎么取值做差

求指点啊

表达能力有限，可能没说清楚  有疑问请qq问小弟
