This is Amogh here, a Masters student at Stanford = University. As a first step towards exploring CoDel, we're trying to re= produce the results on EC2 using OpenFlow + Mininet and then take it from t= here.

So far, I have CoDel with kernel 3.3 (Thanks for the deb packages! More= on kernel 3.4 later), with the codel specific iproute2 patch installed.
With htb qdisc at root, and CoDel children I have an output as follows= :

---------
tc -s qdisc show dev eth0

qdisc htb 1: root refcnt = 2 r2q 10 default 12 direct_packets_stat 770

I was wondering why I get an Unknown qdisc= , optlen=3D32 error, even after using the codel-specific iproute2 from Git.= I noticed that the Git package has fq_codel specific code (I am using base= Codel in kernel 3.3), is it not configured to handle this?

Thanks for your help, excited about CoDel !! Let us know if you have an= y suggestions.
