Hi Jonathan,

Thanks!

First, we noticed that cobalt_cache_init method was not implemented in ns-3 COBALT, so we implemented it (but this wasn't the main reason for the wrong behaviour).

Later, we found that the data types used in the implementation of COBALT in ns-3 were different from those used in Linux.

e.g., uint32_t was used instead of int64_t for the variables with datatype ktime_t in Linux.

Results improved considerably after these changes.

We will update the wiki with latest results.

Regards,

Shefali Gupta

That does look considerably improved. What was the problem in the end?

Now would be a good time to regenerate all the test graphs, and make sure there are results for each test for each qdisc tested. Ideally all graphs should be generated from the same run(s), to ensure their data is mutually consistent.
