Hi guys,
I have a problem about how to use TTL info in RED code segment.Like
this:
//modify file: red.c
...
/*
* Make uniform instead of geometric interdrop periods.
*/
double
REDQueue::modify_p(double p, int count, int count_bytes, int bytes,
int mean_pktsize, int wait, int size)
{
double count1 = (double) count;
if (bytes)
count1 = (double) (count_bytes/mean_pktsize);
if (wait) {
if (count1 * p < 1.0)
p = 0.0;
else if (count1 * p < 2.0)
p /= (2 - count1 * p);
else
p = 1.0;
} else {
if (count1 * p < 1.0)
{
//modification!!!
//=========================
p * = (double) ttl() /(double) TTL_START;
//=========================
p /= (1.0 - count1 * p);
}
else
p = 1.0;
}
if (bytes && p < 1.0) {
p = p * size / mean_pktsize;
}
if (p > 1.0)
p = 1.0;
return p;
}
/*
*
*/
...
The modification is failed.How to solve this problem?
Thanks!
