Hello all!
We are working on implementing Adaptive RED over existing RED code that
can be found in /sys/net/altq/altq_red.c and /sys/net/altq/altq.h. We
have added the following fields and functions to the source:
1. In /sys/net/altq/altq_red.h
Added to struct red_t:
struct callout adaptive_callout;
int target_min;
int target_max;
2. In /sys/net/altq/altq_red.c
Functions added:
void red_adaptive_timer(): function that is responsible
for scheduling a callout for red_adaptive_algo() every 500ms
void red_adaptive_algo(): function that adjusts the drop
probability.
The most important part of the algorithm is the fact that it is called
every 500ms. We are unable to make that happen. We found resources
online pointing us to use callout_init(), callout_reset() and
callout_schedule(). However, we couldn't find documentation on how to
use them correctly and in what order.
Would really appreciate it if someone could point us to useful
resources, or could give us an example of using those functions.
Thanks for your time.
Warm regards,
